There is no equipment that never breaks, and pumping stations - even if they are from the most famous manufacturers, are no exception. What is very pleasing is that the causes of malfunctions often do not lie in the pump itself, and the problems are eliminated quite easily. What are they expressed in, and for what reasons?

This will tell our small instruction. And after watching the video in this article, you will find the answer to the question: “What if the pumping station for water supply does not work?”.

Correct connection is the key to success

Before you start talking about repair, it should be noted that with proper maintenance  water supply system, which is carried out in the home with their own hands, it may not be needed.

So:

• Initially, it all depends on the correct installation - and not only the station itself, but also the pipeline. Therefore, we will give a few useful tips for arranging a home water supply network.

Such important details

After all, what is it? This unit consists of a surface centrifugal pump with a built-in ejector and an induction motor, a membrane tank and several control devices. The power of the station depends on the number of stages in the pump, that is, the impellers.

By the way, all this can be put together and independently, individually selecting each element. The essence of the water supply system does not change from this.

• Another name for the membrane tank: accumulator. This is a tank of a certain volume with a nipple for air injection and a membrane, which, in case of damage, is not difficult to replace. The membrane tank is equipped with two pressure sensors - for monitoring the lower and upper values. It is at their command that the pump turns on or stops.

• A pumping station is traditionally connected to the mains supply via an electric cable (see). If the wire length provided by the manufacturer is not enough, you have to decide to purchase it yourself. It should be noted that the correct selection of cable for the normal functioning of the pump plays an important role.
• They do this with the help of existing tables, according to which, knowing the motor power, rated current and wire length, its cross section is determined. And since we are talking about the cable, we also recall the need to ensure its tight connection to the unit. It turns out to be of the highest quality when using inlet and shrink sleeves with mandatory grounding. One of the connection options is in the photo above.

• In addition to the cable, you also have to purchase elements for the suction pipe device yourself - these are either hoses (see) or pipes. Both of them should be reinforced, but this also has its own catch, as some of them are focused on rarefaction, and others on pressure. Their price depends not only on the length, but also on the option of reinforcing the product.
• When connecting the hoses, it is extremely important not to confuse their purpose, otherwise, vacuum may occur during suction. Typically, the hose is already equipped with a non-return valve at the factory, and when connected it remains only to tightly seal the place of its connection with the suction part of the pump.

• The pumping station itself must be firmly installed and fixed, and in winter it must be provided with the proper temperature conditions. The diameter of the pressure pipe should be related to its length: the further the feed is made, the larger the pipe size should be. And the fewer turns and taps on the water main, the more stable the water pressure in the system will be.

Problems typical for centrifugal pumps

First of all, before the initial commissioning of the station, the pump is filled with water. It is also necessary to bleed air through the plunger - a special device in the upper part of the body. When part of the air remains inside, the supply will either not be at all, or the pressure will be very weak.

At the same time, the operation of the station is usually accompanied by unpleasant noise:

• A decrease in pressure less than the nominal value also occurs due to clogging at any point on the suction system: the pump wheel blades, the filter screen or the supply pipe. Usually setting a filter rough cleaning  on the suction hose helps to cope with this problem.

• In general, if we argue from the point of view of geometry, the pressure can be considered the height of the rise of water, which is carried out due to the energy generated by the pump. And if this distance exceeds the capabilities of the unit, then even the correct filling will not help him achieve rated performance.
• Simply put, if the station is designed to supply water from a depth of seven meters, then putting it on a well a ten-meter well does not make sense. Moreover, in such a situation, the phenomenon of cavitation (vaporization) can occur - and this has a detrimental effect on all the working parts of the pump, especially on the impeller.

Here, the temperature of the pumped liquid is also of great importance. With its increase, the suction height, due to friction losses, is significantly reduced.

How to protect the station from damage

Station pressure indicators are monitored by means of pressure gauges installed on both the suction and the supply pipelines. Deviations of their values \u200b\u200bin one direction or another, indicate problems, the cause of which should be ascertained as soon as possible.

• For the operation of the pump, it is very important that the shaft always maintains a given direction of movement. To prevent it from unwinding in the opposite direction, a check valve is placed on the discharge pipe.

• When installing the pipeline, it is imperative to make a bias towards the supply. This will prevent air from entering the water stream. Also, in order to avoid this problem, the suction pipe must be immersed in the liquid at least 50-80 cm.
• Longevity of operation to a large extent depends on the smooth rotation of the shaft. If appropriate measures are not taken when a run-out occurs, all seals begin to wear out intensively.
• The condition of bearings and seals depends mainly on the alignment accuracy. But when it comes to pumping station, you can not worry about this, since its elements are centered by the manufacturer during the assembly process of the unit.

The main task of the station owner is to correctly calculate the diameter of the supply pipe. Then it will not create excessive voltage, which as a result is transmitted to the pump.

If you have problems

So, if the problems nevertheless appeared, we are looking for the cause of their occurrence, and take measures to eliminate it. For example: your pumping station runs jerkyly.

Here, most likely, the problem is in the accumulator. After all, what is he like? This is a sealed metal container, divided inside the membrane into two compartments - in one there is air pumped through a nipple, and in the other there is water.

• Moreover, the water does not come in contact with the walls of the container body, but is located inside the membrane chamber. This part is the most vulnerable part of this design. As a result of regular stretching and contraction, rubber loses its elasticity over time, or even breaks.
• If you see that the station spits out water, as it were, that is, it delivers it with high pressure, but in small portions, after which the pressure gauge drops sharply to zero, it is necessary to check the integrity of the membrane chamber.

• When, when you press the nipple of the air injection, water flows out of its hole, it means that the rubber part has broken through and needs to be replaced. There are no special difficulties here: the bolts are unscrewed, the old one is removed and a new membrane is installed. After reassembling, air is pumped into the chamber - and that's all.
• Sometimes the unstable operation of the station depends not on the integrity of the membrane, but on the pressure regulating device. It is expressed in the fact that the start-stop of the pump occurs too often. Often the pressure switch is clogged with dirt and scale, and it is worth cleaning it, as the problem of the pump can be solved.

• To understand the essence of the problems, you need to know how the pumping station works in principle. And the essence of its work is as follows: when the hydraulic tank is filled to the upper level, the pump is turned off. Its launch should not occur at the time of opening the crane or, for example, launch washing machine, and then, when the water level in the chamber reaches the minimum value. This process is controlled by level sensors.
• And suddenly, the pumping station turns on at night, when no one uses water, and all the taps are closed. The conclusion suggests itself: somewhere there is a leak. Hence, an urgent need to revise the entire system. If there is no breakthrough in the pipeline, you need to inspect all connections for depressurization.

• Even a small leak is enough for the pressure to drop, and the station begins to run into operation uncontrollably. How to eliminate it, you need to be guided by the circumstances - it may be necessary to replace the flange, or perhaps you should rewind the thread and tighten the nut well.
• And here is another quite common problem: the water pressure has already reached the norm, and the station does not want to turn off. In this case, the cause may be an undervoltage in the network at which the pump motor is not able to reach the rated power. Check the voltage with a tester, and if everything is okay with this, most likely, the pressure switch settings were lost, or it failed.

• So that voltage drops in the network do not affect the operation of the station, it must be connected via a transformer. After all, not only a decrease, but also an increase in voltage can disable the pump motor. As for the reconfiguration of the pressure sensor, it is carried out by turning in one direction or another the regulator nuts located under the cover of the device.
• In conclusion, we will discuss the situation when water is not flowing from the tap when the station is started up. The problem, most likely, is that the pump performance clearly exceeds the well flow rate. Simply put, water consumption is higher than its natural inflow into the water intake.

In this case, all the taps must be closed and wait until the well is filled again. This, of course, is no way out of the situation. But if there are a lot of water distribution points in the house, as well as powerful plumbing fixtures like a jacuzzi or shower, it makes sense to think about deepening the old water intake or building a new one. Otherwise, you will have to reduce water consumption.

The main element of any autonomous water supply system is a pumping station, which, like any other technical device, can periodically fail. In order to return the pumping equipment to working condition, you can use the services of specialized companies or do the repair of the pumping station with your own hands. However, before proceeding with the repair of such equipment, which is quite complicated in technical terms, it is necessary to identify the reasons why the water pumping station does not function.

There are many causes of malfunctions in the pump station. They can be associated with a lack of power supply, improper water supply from the water supply source, breakdown of the pump itself, failure of the accumulator or elements that provide automatic control of the equipment. Many of these reasons that lead to the fact that the water supply stations do not work or function incorrectly can be identified and eliminated at home, and professional skills and sophisticated equipment will not be required for repairs.

The device of pumping stations

Pumping stations, which are often called hydrophores, are now actively used to organize autonomous water supply systems for country houses and cottages, so the question of how to repair such equipment on your own, if necessary, is quite relevant. Before you understand how to do the repair of the pump station with your own hands, you need to understand what such stations consist of and by what principle they work.

A pumping station for equipping a domestic water supply system, which pumps liquid into the piping system, is installed on the surface of the earth, as close to the well as possible (as far as possible), and works from an electric power supply network. The main structural elements of pumping stations that ensure efficient and uninterrupted operation of such equipment in automatic mode are:

• the water pump itself, which pumps water from the well or well and pushes it under pressure to the outlet pipe (to equip the pumping stations, it is mainly a submersible pump, but a surface pump);
• water intake hose, which is immersed in water at the highest possible level;
• non-return valve that prevents water from the suction pipe from falling back into the well or well;
• a mesh filter installed in front of the non-return valve and cleaning the water injected from the source of particles of dirt and sand, the ingress of which into the inside of the pump may become one of the reasons for its failure;
• the pressure sensor installed after the pump is located on the pressure line (the main task of such a sensor operating in automatic mode is to turn on the pump if the water pressure in the water supply system drops to a critical value and turn it off when it reaches the required parameters);
• a water flow sensor, which is installed before the pump and does not allow it to idle (when water stops flowing from a well or a well, such a sensor automatically turns off the device, preventing it from overheating);
• a manometer that allows you to measure the water pressure in the pipeline created by the pumping station.

Failures of the pumping station, as mentioned above, can be determined by a number of reasons, the exact clarification of which will allow you to quickly and efficiently perform repairs, returning the equipment to working condition. When diagnosing to determine the cause of a pumping station breakdown, it is not necessary to use sophisticated equipment and have professional skills. It is possible to identify most typical malfunctions of pumping stations both by external signs and by using devices that such equipment and a water supply system were originally equipped with.

Among the malfunctions of the pumping stations, several of the most characteristic can be distinguished, which each user is able to identify and fix independently, using the advice of specialists during the repair.

The pump is running but no water is entering the system.

When starting up the pumping station, it may happen that the pump with which it is equipped works and liquid does not enter the water supply. To determine why the pumping station does not pump water, it is necessary to analyze the individual parameters and operating conditions of the elements included in the equipment.

• First you need to evaluate the technical condition and the correct operation of the check valve, which is located on the suction pipe in the inner part of the well or well. Very often, the pumping station does not pump precisely because this valve is clogged with sand and dirt: without opening, it simply does not allow water from the well to flow to the pump.
• Check whether there is water in that part of the pressure pipe that is located between the pump and the well. If there is no liquid there, then, accordingly, the device has nothing to pump. Often this situation occurs when a power outage occurs and the pump station stops working. In order for the pumping station to start working normally again, it is enough to fill this part of the pipeline with water, for which a special hole is provided in it.
• It is necessary to check (with a disassembled pump) how large the output is between the inner walls of its housing and the impeller. The most intensive such production is formed in those cases when water is pumped, which contains a large amount of insoluble impurities (a kind of abrasive). If this is precisely the reason for the lack of water in the water supply system when the pumping station is running, it is necessary to repair the pump, which consists in replacing the impeller and the casing of the device, or its complete replacement. In the event that you find accessories suitable for the model of your equipment, you can repair the water pump yourself.
• It is also necessary to determine whether there is water (and at what depth, if any) in the well or well itself. If there is water in the source of water supply, then the problem is solved simply: just lower the supply hose or pipe to a deeper level of injection. In this case, it is necessary to comply with the operating instructions of the pumping equipment in order to subsequently avoid its repair.

The pump station runs jerkily

The pumping station, which operates in automatic mode, can often turn off and on, which indicates a malfunction. This nature of the operation of the pumping station, in which it is constantly turned off and on, is called jerking. This should be a signal to check (and, if necessary, repair) individual elements of the system.

If the pumping station operates jerkyly (it turns off, then turns on), the pressure in the air chamber of the hydraulic tank should be measured. To perform this procedure, you can use a car compressor equipped with a manometer. If this parameter is below the norm in the air chamber or pear for the pumping station, it must be raised using the same autocompressor. A repeated pressure drop in the air chamber of the device indicates that there was a depressurization of the system, the location of which must be identified. In the event that the joints have lost their tightness, then the accumulator repair is not required, just replace the sealing tape in such places.

The case of the hydraulic accumulator can also lose its tightness if a crack or hole has formed in it. It is not difficult to repair the accumulator with your own hands in this situation: for this it is enough to close the crack or hole that has been created using the “cold welding” composition.

Why is the pumping station often turned on and off during operation? The answer to this question may also lie in damage to the accumulator membrane. In such cases, the solution to the problem is to replace the accumulator bag or such a membrane.

Replacing the diaphragm in the accumulator

Unscrew the flange. Remove the membrane and clean the tank. The new membrane should fit the flange.
   We insert and straighten the membrane, install the flange. Check the nipple and pump up the pressure. Check the pressure after some time.

Repair specialists often ask why the pump station often turns on or why the pump station does not turn off at a time when the pressure of the liquid in the water supply system exceeds the norm. This is usually due to a breakdown or malfunction of the pressure switch. Such malfunctions can also cause the pump station to not hold the water pressure in the pipeline. Repairing a pressure switch is a rather complicated procedure that can not always be done with your own hands. That is why in many cases they do not repair the pressure switches of the pumping station, simply replacing such a sensor with a new one.

Unstable pressure of the flow of water coming from the pumping station

One of the fairly common situations during the operation of pumping stations is the supply of water from taps with pulsating shocks, which indicates that the water supply system draws in air from the outside. To identify the place where air enters the pipeline, it is necessary to carefully check for leaks of all the connecting elements present in the area located between the well or the well and the pump station.

If the pumping station does not build up pressure or delivers water to the pipeline in a pulsating mode, this may also indicate that the water level in the source has decreased or that a hose or pipe of the wrong diameter is used to pump out the water.

When choosing a hose or pipe for placement in a well or well, it should always be borne in mind that their diameter should be the smaller, the lower the height of water intake from the source.

Pump station auto shut-off system does not work

The question of why the pumping station does not turn off automatically is quite common. A pump station operating in such a mode, which is considered emergency, cannot be operated; it should be immediately disconnected from the power supply. Otherwise, you may encounter a quick failure of the equipment, which means that you will need a more complex and expensive repair of hydrophore.

Why the pumping station does not turn off for a long time? The reason is incorrect operation or failure of the pressure sensor. A malfunction of this device, which operates in automatic mode, can cause the pump station to not turn on at the moment when the pressure of the fluid flowing through it decreases in the pipeline. In most cases, this problem is solved quite simply - by adjusting the sensor to the required pressure on and off the pump.

The pressure switch may not work properly for the reason that the elements of its internal structure are covered with salt deposits. In such cases, it is enough to disassemble the sensor and clean its internal parts from such deposits.

Pump station does not turn on

In most situations, the station does not turn on (and, accordingly, the pump-pump does not work) due to an open circuit, oxidation of the contact group elements and malfunctions in the pressure sensor. In addition, the causes of malfunctions can lie in the burnt winding of the drive motor, as well as in the failure of the starting capacitor.

With repair procedures such as repairing breaks in the power supply circuit of the station, stripping the contacts of the starting device and replacing the capacitor, as a rule, there are no problems. However, in order to rewind the electric motor, it is necessary to know how to disassemble it and how to replace the burned winding in it. That is why many users of pumping stations, when the drive motor burns out, simply replace it with a new one, avoiding repair.

Often when you start a pumping station, which has not been used for a long time, a characteristic hum occurs, but the equipment does not start to work. The reason for the occurrence of this situation is that the impeller of the pump of the pumping station simply “stuck” to the body of the device and cannot budge. In this case, it is necessary to partially disassemble the pump of the pump station and manually move its impeller from the dead center.

How to correctly install the pumping station

To less often ask why the pump does not pump water from the well or does not feed it correctly into the system, serious attention should be paid to the installation of the elements of the pumping station. The correct installation of water supply systems with submersible pumps is of no less importance, since repair of a submersible pump or its replacement is also an expensive procedure.

So, when performing the installation of pumping stations, one must strictly follow the following recommendations:

• prevent bending and deformation of pipes used for installation;
• ensure absolute tightness of all connections to prevent air leaks into the system;
• be sure to place a check valve and filter element on the feed pipe;
• immerse the lower end of the inlet pipe into the water in the well or well for at least thirty centimeters (the distance of the end of the pipe to the bottom of the water supply source must be at least twenty centimeters);

Residents of private houses, cottages, country houses are often urgently in need of installing a pump structure for pumping water from a well, well. For some, this is the only way to have water in the room. Therefore, when, one day, the pump stops buzzing, it is urgent to understand the origin of the breakdown.

If the pumping station stops pumping water, it is urgent to find the cause of the breakdown.

Often the stumbling block is air that enters the pump along with the fluid. Everything can be prevented, only initially you need to find out from which elements the pump structure is assembled.

Key components of the pump unit

There are many types of stations, but the basic components are inherent in everyone.

1. Self priming pump. The principle of operation: the pump independently draws fluid from the recess using a tube, one end of which is in the well, the other is connected to the equipment. The pump is located a short distance from the water tank. The depth of the tube is also adjustable.
2. All units are equipped with a hydraulic accumulator. The vessel, using the energy of a compressed gas or spring, transfers liquid under pressure to the hydraulic system. It accumulates hydraulic fluid and releases it at the right time, thereby avoiding jerks of water in the system. Outside it is metal, inside there is a membrane of rubber, a gas cavity filled with nitrogen is placed above it, and a sub-hydraulic cavity. Water is filled until the pressure in both cavities is equalized.
3. Electrical engine. By means of the coupling, it is connected to the pump, and to the relay - by means of an electrical circuit. Due to the fact that the pump does not turn on for short fluid intakes, the motor does not wear out.
4. Air outlet pipe.
5. Collector element.
6. Pressure gauge. It allows you to monitor the level of pressure.
7. Relay. By changing the pressure, by the method of opening / closing contacts, it supports the independent operation of the equipment.

The main purpose of pumping stations is to support continuous pressure in the water supply structure. In order for all components to function like a clock, it is important to choose the right amount of accumulator and control the connection between the regulator and the pump itself.

Unit operation

When turned on, the first electric motor enters the business, it starts the pump, and it pumps the gradually incoming liquid into the accumulator. When the battery is full to the limit, excess pressure will build up and the pump will shut off. During the loosening of the tap in the house, the pressure decreases and the pump starts again.

When the pump structure is installed, it is connected to the pipeline, and the suction elements with a water intake device are placed in a recess with liquid.

The house has a battery connected to the water supply. The pipes are filled with water when the pump starts. When the pressure in the station reaches the desired peak, the pump shuts off.

The pump unit will solve the difficulty of supplying water to houses, baths, summer kitchens, outbuildings and other premises on the territory of your site. Having familiarized with the details of the station, it is necessary to study the possible causes of the failure of the device and methods for their elimination.

Failures that are most often encountered

In the process of using any equipment, a moment comes when it either wears out or breaks. So in the second case, it would be important for the owner to understand the causes of damage. Here is a short list of reasons that disrupt the operation of the pumping station:

• no electricity - commonplace, but also not excluded, since the operation of the unit directly depends on the electric current;
• the pipeline is not filled with liquid;
• pump malfunction;
• the hydraulic accumulator is broken;
• damaged automation;
• cracks in the housing.

Popular issues and how to fix them

The pump turns, but does not pump water

What to do when the station does not pump water? A frequent cause of failure is a lack of fluid in the pipes or in the pump itself. It happens that the unit is functioning, but does not pump water. Then the tightness of the entire water supply should be inspected for places where the pipes are poorly connected.

Check that the pump is not empty. The non-return valve is not working properly. Bandwidth should be one-way. This is one of the most important parts of the station, because, after turning off the pump, it prevents water from draining back into the well.

Diagram of a pump station valve that may become clogged

It happens that the valve is clogged and does not physically close; debris, salt, grains of sand can get into it.  Accordingly, the liquid does not reach the pump. We solve the problem.

Before untwisting the unit, we recommend checking the voltage of the electric current. It happens that it is below normal, and the pump is simply unable to turn on. We check the presence of fluid in the water supply system and in the pump. In case of its absence, it is only necessary to add it to the pump through the prepared holes or to immerse the end deeper into the well for suction. Keep the gap between the water source and the pump within normal limits. If the pumping station does not shake, it is worth solving the difficulty of depressurizing the water supply system or replacing the check valve.

When, after all the manipulations, the equipment buzzes, but does not pump water, foreign particles get into it. To find out - unwind the pump and change its impeller or body. Sometimes only installing a new one will help.

Frequent Inclusions

Why did the pumping station turn on much more often? It turns out that it does not fully set the desired pressure and turns off. Therefore, it works in fits and starts.

There is a solution. When you notice that this happens, first check the hydraulic tank for serviceability. On the back of the tank there is a connecting tube, when it works correctly, when you press it, air comes out. If water flows instead of air, it indicates that a membrane has torn inside. Replacing it will work.

Another culprit in the lack of necessary pressure in the hydraulic accumulator may be a crack in the shell at the seam. Fix the hole in any way known to you.

Having checked, as it should, the tank, sometimes, it is enough only to independently pump the air in the required amount through the nozzle. Due to the fact that the joints of the suction pipe have openings, water will be supplied intermittently. It is important to examine it in detail and patch the holes.

The pump simply does not start

The primary actions are checking the current and normal voltage in the network. Next, examine the relay contacts. Burnt parts must be replaced. The winding should be whole. If you feel a special smell of burnt substances - the motor burned out.

Pump is buzzing but not spinning

When the pump starts, but does not rotate during power-up, the capacitor is broken, or the impeller could adhere to the shell. This is usually found in pumps that have been left unattended for a long time. In this situation, when the capacitor becomes unusable, it is changed. With the impeller is easier. It should be brought into action by mechanical action. Scroll hands several times.

The unit runs without stopping

We noticed that your pumping station is operating continuously, without stopping - here lies the violation of the pressure switch. Examine the device inlets. They can be blocked by pumped debris in the liquid. It is necessary to adjust its action, set the recommended pressure in the battery. First turn off the power and drain all liquid from the tank. Record the pressure level on the pressure gauge when turning the pump on and off. Remove the cover.

There will be two screws: the top is the larger one, the bottom is the smaller one. Large - adjusts the shutdown pressure. It must be turned in the required direction: either reduce the “-” pressure when turning off, or vice versa “+”. We turn on the power again and record the shutdown result. We perform this manipulation until we achieve the desired result.

A smaller screw adjusts the difference between on and off pressure. Its setting is similar to the setting of the top screw. It remains to find out her norm. The pressure difference is 1.0-1.5 bar. After adjusting the pressure, close the lid, draw water into the structure and connect to the network. Be extremely careful when configuring the relay.

Pressure switch circuit, improper operation of which can provoke a breakdown of the entire station

Incorrectly adjusted pressure can cause a breakdown of the entire system.

By aligning the pressure in the hydraulic accumulator, the user calms down and forgets to continue to monitor him. But the correct level of pressure will ensure the life of the membrane in the battery and, in direct proportion to the life of the entire structure.

In order to keep the pressure at the required level, it is necessary to measure the air pressure in the air cavity when the hydraulic tank is turned off. Turn off the voltage, open the tap next to the pump, and drain the liquid. Also, this procedure can be done when the unit has not yet been used in operation and has not been connected to the network.

We measure the pressure with a manometer. The main thing is that in the battery it was 10% lower than when starting the pump. Factory settings are usually 1.4-1.5 bar. So, if you have changed the level of the pressure switch, then by all means change it in the hydraulic vessel.

Provided that you did not interfere anywhere, it is still worth checking this level once a year. The main thing is to keep the pressure at the set mark. If it falls, it is easy to fix it with an ordinary tire pump, pumping air into the tank cavity.

It is recommended to monitor the excellent battery service. The liquid contains a small percentage of dissolved oxygen, which contributes to the progressive decrease in the volume of the rubber membrane in the battery. Inside, special valves are mounted through which excess air flows out. Therefore, it is required to remove fluid from the membranes once every 60 days. Before this, do not forget to turn off the electricity, drain the water from the tank (up to three times).

Prevention

In order to protect the pump from empty work, when no liquid enters it, so that the motor does not burn out, manufacturers came up with some ways.

1. Float. The float cable is connected to the rupture of one of the phases supplying the pump. When the water in the well drops below the required line, the contacts in the middle of the float open and stop the equipment.
2. Pressure switch with dry run protection function. When the water pressure drops below 0.4-0.6 bar, the connections diverge and the pump decays.
3. Relays with flow sensor. When the actual flow of water is not carried out, the relay stops the platform.
4. Level switch - an electronic board with three sensors, it is placed in a dry place, the house. One beacon remains on the board, the other two are lowered into the well. When the water level drops below the control beacon, it signals the relay and it turns off the power to the station.

It will cost less than replacing or repairing the entire station.  Without delay, the preventive measures taken, the check of the pressure switch in the water supply structure contribute to the excellent functioning of the unit.

We hope you were able to figure out in what situations the pumping station does not pump water, the reasons and repair options.

Main malfunctions of the pumping station

Your pumping station has stopped working. What actions should you take?

If the pump does not work, first check if there is voltage in the mains. If there is voltage, then your next step should be to check the reliability of the electrical connections. If the pumping station is connected for the first time, then it is necessary to check the correctness of the connections. If these actions do not give results, then one of the possible reasons may be a blocked impeller. Before inspecting the pumping station, be sure to turn off the electrical power. After that, try turning the motor shaft. If the impeller is blocked, you can carefully eliminate this malfunction of the pumping station yourself. Sometimes the pump may not work if the starting capacitor fails. Such a malfunction is eliminated by replacing the starting capacitor.

Consider a malfunction when a running pump does not pump water. It can be in such cases:

1. The pump does not pump water because there is air in the suction line and housing. To eliminate the breakdown that has arisen for this reason, you must first check the tightness of the suction pump, then, after turning off the pump, unscrew the plug from the filler hole so that the air there is released. Then you need to add water and start the pump.

2. The same malfunction can also occur if the water level in the water source is too low, and sometimes the suction pipe is simply not installed correctly. To eliminate the malfunctions that arose for the above reasons, it is necessary to check the water level in the source of water intake, and also to check whether the installation of the suction pipe that you installed matches the installation scheme given by the manufacturer in the technical documentation for the product.

3. Very often the above problem occurs in cases where the check valve on the suction pipe is either clogged with dirt or is not working properly. Clogging of the ejector or nozzle of the ejector also leads to the same result. These problems are eliminated by cleaning the valve and ejector from obstructions.

A common problem is a decrease in the pressure of the water supply. This can happen in the same cases that are listed when the pump station breaks down, when the pump does not pump water (described above). Remedies are the same. But also this failure can occur for other reasons. This problem may be due to incorrectly set pressure. The pressure can be adjusted by raising the level. The same problem occurs when voltage drops in the mains. This problem is solved by connecting a voltage regulator.

The pump may turn on and off too often. If this occurs due to damage to the membrane, the membrane must be replaced. The same problem can occur if the pressure accumulator is low in the accumulator. It is possible to raise the pressure if air is pumped into the hydraulic accumulator. The required pressure level should be 1.5 atm.

Why does the pump not turn off?

If the pump does not turn off, check whether the pressure switch is set correctly. If the pressure is set too high, the level must be adjusted. The pump may also not turn off due to a drop in water level, which leads to air entering the suction line. In this case, remove the air (described above). Also, the pump may not turn off due to the fact that the pyatnik is clogged, this is due to the hardness of the water. Therefore, it is necessary to remove the pressure switch and clean the passage. (see photo). There is another case where the pump may not turn off: this may be due to the fact that there is somewhere a gap in the line between the valve and the pump station, as a result of which there is a leak and the pump cannot pump the necessary pressure. To eliminate, inspect the piping, remove the valve from the well and check the tightness of the connection. Also, the cause of the malfunction can be quite commonplace - this is the failure of the valve itself.

Sometimes, during operation, the engine stops. This is due to engine overheating. In this case, it is necessary to disconnect the pump from the power supply, eliminate the cause of overheating.

To summarize, it must be said that the correct installation of pumping equipment, strict observance of the operating rules and respect are the key to the long life of your pumping station.

1. The check valve must be with a brass stem.
2. Water leakage may be in the pipeline. The pump station must be installed horizontally to the water inlet in the well or in the pit near the well or in the basement of the house, but a prerequisite for horizontal entry of the pipe into the well, any deviation is undesirable.
   3. Water must be added to the pumping station from the top, until the station works

• #2

  all the same, I will put a new valve due to the fact that during the night I poured 3 times into the system and the water all the time left without connecting the source.

• #3

  good afternoon, tell me please, I had to disconnect the station (pedrolo) from the well pipe for repair. The non-return valve, as it turned out, is directly at the station, but probably it is not on the pipe. Since the water has left the pipe. It is impossible to pull out the pipe, and the station cannot pump water. What do you advise?

• #4

  The most proven way is to put a check valve in the well, and pour water directly into the pyatnik. But since you say that there is no way to raise the pipe from the well, then you can try, put a crane with an American in front of the valve. After installation, it is necessary to disconnect the tap from the valve, open the tap and pour water there. It’s best to put some kind of water tank and supply water through the hose to the pipe, you must take into account that the water will immediately go into the well, so when you are sure that the pipe is filled with water, you must immediately turn off the tap to create a vacuum in the pipe, which makes it impossible for water to drain into the well. After that, it is necessary to attach a tap to the valve and pour water directly into the station. After we turn on the station and open the crane, the station should start.

• #5

  thanks for the advice, but not everything is clear. What is an American?

• #6

  This is a connection that allows you to quickly disconnect the joint http://cdn.gollos.com/files/920/amerikanka.jpg

• #7

  Thanks! I will try.

• #8

  Good day! Everywhere where it was possible to suck in air, they eliminated. They cleaned them. There is no necessary supply and strong vibration on the discharge line. It should be 12.4 m3 / h, and then 9 m3 / h. The three-plunger pump 1-3T. What do you advise? And other pumps work fine

• #9

  It is not clear what kind of pump? Which company?

• #10

  I buy a pedrollo station from hand. Tell me how in the field to check whether everything is working properly. Thanks in advance for the informative answer

• #11

  You can put a bucket and pour water, then connect the station and run a hose or pipe into the bucket for suction and send the raised water back to the bucket. It turns out a vicious circle and the station can work for a long time to check.

• #12

  Please tell me what to do. When I operate the pumping station, the pressure gauge is "O", but the pump does not turn off the water, a small blow to the relay turns off.

• #13

  It is not clear or is pumping pressure into the system? Most likely you have a gap in the pipeline or a limit switch in the well has clogged.

• #14

  So it’s not clear with all this, water with good pressure flows from the tap.
     "" I have when operating the pump station on the pressure gauge "O", but the pump pumps water while it does not turn off, a small blow to the relay turns off. ""

• #15

  Most likely you have a clogged relay or pyaternik see article above. Or maybe the pressure gauge just doesn’t work. Be sure to check the pressure in the receiver, it should be 1.5 atm. You can try to reduce the pressure in the relay to turn off the station, for this you need to slightly loosen the small spring. If this does not help, replace the pressure switch.

• #16

  thanks for the advice, I'll try.

• #17

  
     (Tuesday, March 31, 2015 18:22). It turned out to pump water but the hemorrhoid got out - with an empty tank, the station pumps water, but when the pressure drops and the station starts, it does not pump water and does not turn off until all water comes out of the tank. That is, I opened the water tap, the station turned on , the crane shuts the station, threshes it, opens the tap again, wait until the water runs out, then air is smoked and water goes again, you close the tap, the tank is pumped and the station turns off) these are the tricks. about 8 meters to the water in the pipe. there’s only one pipe 32. I’m tired of this already, as it’s a summer residence — they went without me — I arrive at the station threshing (it turned out already the second day) everyone smiles and don’t know what to do. called specialists, so they’re generally entertaining, they came, had a smoke, offered to hammer another well ... well, we sent them to hammer in another place. I will be very grateful for the good advice!)

• #18

  Good afternoon, PLEASE TELL me for 5 days I can’t identify the cause of the pump malfunction, the problem is this: not long before the breakdown the pump pumped up weak pressure and then refused to work at all, I cleaned it, changed the ceramic stuffing box, checked all the pipes and connections everything is in order, it turns on and gives a weak pressure, in general the engine runs, but the water does not run, what should I do? pump 3 years omnigena with impellers. By the way, today I discovered that it does not hold the check valve, could it be the fault of all this? I almost forgot, I removed the pump from the pipes and dipped it into the pool, it pumps water well, it is gaining pressure, the automation is working. But when I connect it to the place, it does not work AS SO ???

• #19

  Roman, the valve must be replaced, it is desirable that the stem in the valve be brass. Most likely you have a gap in the pipeline.

• #20

  Today I bought and installed a new valve, the water in the system doesn’t drain, I just conducted one more experiment, removed the pump and connected the wrong pipe to it and a 15 meter long hose so as not to sin on the pipes again and he tried to pump but pressure it’s very small and after a minute of work it completely turned off (so now I definitely think that this is wear of a snail or impeller, but I don’t understand how it happened in such a short period of time and it seems like everything was okay with visual contact. I’m completely confused.

• #21

  It is difficult, you can advise something remotely without seeing the pump. Judging by your description, the impeller is clogged. In general, a woman’s stocking should be worn on the pump. If the pump still buzzes, but does not spin, then the impeller is most likely clogged with debris, it is necessary to untwist and clean it. If the pump is no longer buzzing, then mudflowing, only the new pump will help you, because repairing the old one will cost you like new.

• #22

  Good afternoon. The pump station for some time (five minutes) delivers water from the river, then "sneezes" and stops working. What can be tell me please.

• #23

  But the fact is that the pump works and the impeller spins, and even pumps water without pipes and hoses but with little pressure, and as soon as I put it on the pipes or put on a hose it either gives out a small trickle or does not pump water at all, but the impeller spins and the pump itself works good.

• #24

  Dmitry, most likely your system is airing, you need to fill the station with water. The pipe entry into the station should be horizontal.
     Roman, it’s obvious that there is a problem with the pump, I recommend showing the pump to the repairman.

• #25

  If the pump rotates, it doesn’t turn on. If you turn the impeller, it starts to work. I cleaned the contacts, replaced the capacitor with a new one, the station didn’t stand idle the whole winter. 224v. find the reason. Thank you.

• #26

  They removed the pumping station to tint, set it up, now it pumps water with air, sneezes, especially in the morning after a night break. Tell me how to fix it?

• #27

  Most likely your system is airy! It is necessary to add water to the station itself, and thus displace air. It is also necessary to check the check valve for serviceability and you will be happy and kind. Successes.

• #28

  Thank you so much !!! I will tell my husband that I would check.

     If the station does not build up the necessary pressure, there can be only 3 reasons:
  1. There is a leak or leak in the pipe in the pipe or does not hold the check valve.
     2. The mesh for water suction in the well clogged.
     3. malfunctioning us. the station helped

• #30

  when my engine starts, it first 10-30 seconds just buzzes and can not spin up. and then just starts to download. and during work, his sound changed, he began to hum more and louder. please tell me what is the problem

• #31

  The pumping station stopped turning off (upper pressure was 3). When they started picking at it, it turned out that the rubber bulb was torn. Replaced. Cleaned the pressure switch. Nothing helped. Lowered the pressure to 2.2. Now she quickly pumps up to 2 and for a long time, as if with difficulty, to 2.2. This is not normal and this pressure does not suit at all. What can you advise?

• #32

  Stavr pump does not shut off, new

• #33

  Mila, most likely you have a clogged mesh in the suction line, which is located in the well. Also check the check valve. Check the pressure in the tank, between the bulb and the tank itself, should be 1.5 atm

• #34

  Connected pump station (new). Filled water, Turned on. There is no water.
     He blew air, added water. He started again, there is no water. The air is pumped, checked the pressure - 2 atm. Tell me, there may be a reason because the last 30 cm of the suction pipe are connected to the station with a small counterclone, somewhere around 5-7 mm.

• #35

  It's not about bias! You do not have a check valve, exchange for a valve with a brass stem (core)

• #36

  Tell me, is it necessary to put a check valve on the output of the NS?

• #37

  The check valve must be installed necessarily, if it is not installed, after turning off the station, water will drain back into the well so the system and the station itself will be constantly aired.

• #38

  Ivan)), as I understand it, one valve must be put in the direction of the NS and at the exit that goes to the house ... just most of the pictures on the Internet do not show this, and the seller who sold the station to me said that it is not necessary to put a check valve on the outlet) .

• #39

  Tell me, I have such a problem. After the valve opens, a normal pressure is applied, then the pressure begins to drop. When the pump is turned on, the pressure normalizes, after turning off the pump, for some time the pressure is normal and starts to drop again., Before turning on the pump. I checked the pressure in the barrel, the norm is 1.5 atm

• #40

  And how did you want the pressure to be without jumping? Then put a larger receiver on 300 liters and you will be happy.

• #41

  There is another problem, after rains in the water appears fine sand. I checked the check valve in the well, the whole mesh, there is still a mesh (filter) in front of the pump. Advise how to get rid of the squeak?

• #42

  Yes, but for three years the station worked and there were no visible leaps, but now it has begun to appear.

• #43

  Perhaps you have a very low dive end of the pipe, try to raise it higher. At the end of the pipe you can wear a female stocking, in some cases it helps a lot from the penetration of sand. At the expense of jumps, try replacing the bulb in the receiver. You can also reduce the difference between off and on stations in the relay.

  Hello! I purchased a pumping station Elitech САВ 1000Н / 24. Installation made according to the instructions. Checked tank pressure \u003d 2 atm. Well 25m deep. About 7m to the mirror. The feed pipe D \u003d 32mm was lowered into the well by 13m — how many pipes were there and lowered (maybe this is not right?). Mounted the filter and valve 1 "(brass) at the end of the pipe (in the well). The pump is near the well. He blew air. He turned it on. The pump dialed 3 atm. The pump delivers water. Problem: After the tap is opened, the water flows with a very good pressure (slips a little air). But then the pressure drops (us. station turns on), the water barely barely flows - we can say that it does not exist at all (also with a small amount of air). The pump station does not gain the desired pressure. Close the valve - the station collects pressure. If open the tap everything repeats. ko again. What could it be? Help advice, Thank you!

• #46

  hello, please tell me what is the reason I have a well of 15 meters. The pump is released for 12 meters. Why the pump doesn’t turn off. The 50-liter hydraulic tank is gaining up to 8 automatic telephone exchanges. and the pump works further. I don’t have a pressure switch. what is the reason. thanks

• #47

  Dmitry, I have not seen the pumping station so that it lifts water for more than 14 meters and gives excellent pressure. I am surprised that she generally pumps you water. With such a dive of 13 meters, which is generally not permissible by the manufacturer, read the instructions, there should be a dive of no more than 8 meters. I would recommend submerging no more than 4 meters under water. The fact is that pumping stations are very sensitive to the depth of the suction line, the lower the end, the less water pressure you get 0.8 bar (atmospheres, kgf / cm2). From experience, I would recommend you install submersible pump  not a pump station.
     ALEXEI - in your case you need to install a pressure switch.

• #48

  The pump does not pump water because there is air in the suction line and the housing. To eliminate the breakdown caused by this reason, you must first check the tightness of the suction pump, then, after turning off the pump, unscrew the plug from the filler hole so that the air there is released. Then you need to add water to the pump station and start the pump. If the pump does not start the first time, add water again.

• #49

  Good afternoon! Tell me please. I have a watercolor pump, it pumps water from the basement barrel into the house, it works fine, but after a while it stops pumping, after a power reboot, it starts pumping again ... Tired, walk and switch the machine (

• #50

  Vladislav, most likely you have power surges due to this knocking out the station. Or, idle protection may be included. In the first case, you can put a voltage stabilizer. In the second, you need to look, maybe you are pumping water out of the well.

• #51

  I don’t understand where does the well come if I pump water from a storage barrel. Thanks.

• #52

  And how does water enter the tank?

• #53

  Why does the pump baffle constantly break. WHERE WHERE ARE THE SEALERS. Fence diameter 25

• #54

  Victor, contact a pump repair technician. The main breakdowns of pumping stations are discussed here. The device of the deep pump is much more complicated, which requires additional skills.

• #55

  I guess I asked the question incorrectly. I do not have a submersible pump. The pump is the same as at the pumping stations model JS - 60 600W. I use an electronic pressure controller instead of a hydraulic accumulator (since there is a gas column and using a hydraulic accumulator it was impossible to set the column to the desired temperature of hot water, from the on / off range), a well with a depth of 73 meters, an upsetting diameter of 50, and a water intake of 7 meters, set a fence with a dimeter 25, 15 meters in the casing and 7 meters to the mine with a pump. Of course, it was necessary to put a fence 32, but could not find a drill under this pipe. The problem is that a crack constantly appears in the lid that stands behind the impeller (in which the glands are located), the new one is literally enough for a couple of months. Maybe the pump is starving because of 25 intake pipes. He put the exhaust pump (there is nothing to lomat), the pressure on watering is rather weak. Tell me the reason, I will be very grateful.

• #56

  I would recommend submerging no more than 3-4 meters under water. The fact is that pumping stations are very sensitive to the depth of the suction line, the lower the end, the less water pressure you get 0.8 bar (atmospheres, kgf / cm2). Also, pumping stations with a lift depth of more than 9 meters are not able to give normal water pressure, unless they are injection. I can’t say anything about the crack.

• #57

  Thanks for the advice. Right now I'll try, (after I unsubscribe). One more question; when immersed 3-4 meters under water, will there be enough water for irrigation? After all, all the same, the volume of the well is not like that of a well.

  Nikolay, it’s difficult to give recommendations without seeing the station, but judging by the above, your pressure switch is clogged or it does not work. Before changing the pressure switch, you should find out if the check valve or piping is leaking. It is also necessary to check the bulb in the receiver tank.

  Help, since he’s young enough, they put a pump, installed a hydraulic tank, a battery with protection against dry running, turned it on. The pressure where it goes for watering is simply gorgeous.

Checked the pressure gauge. 4 atmospheres it turns off 1.5 turns on. Relay factory, what could be !?

• #67

  Nikolay, Vladimir, if the water leaves the well or well, then this is not a problem with the station. IF air enters the station, then at many stations there is idle protection, if it is not there, the station will not pump water anyway.
     Denis, very little information about your case, which NA? What are the connection conditions?

• #68

  There is a deep pump, everything is submerged as expected, on the advice of the master. In a straight line we tried without a hydraulic accumulator, the 32nd pressure pipe was two meters high.

  Good afternoon!
     You can tell! I have a two-arm Expo bar machine. Today they did not see the water level in the bottle and the car began to draw air from the surface of the bottle, the pipe did not reach the water, then the pressure did not rise. Then we gave the car time to cool i.e. "recover" for several hours. They turned it on again, the machine is working, but (I don’t know what it’s called correctly) the “bar” on the sensor jumps from 0.9 to 1 every 10-15 seconds. Can you advise something, maybe some professional measures will help?

• #84

  Hello! After idle water station there was a problem - leaking pump. When starting in the area where the pump and motor are connected below, first intensively, then water flows in drops. A thin stream runs from the crane. How to disconnect the pump and what is the problem, in the gasket or in the ceramic-graphite seal station "Belamos"?

• #85

  From experience I want to say that 65% of malfunctions arise due to the fact that the client refuses to read the operating instructions for this device. Beck, if the pump doesn’t get air into the station, this article is described in the article. Oleg, it is necessary to show the station to the repairman.

• #86

  Thanks for the answer!
     Our employee did not keep track of when, at the point, I always check everything myself. You are right, you need to read, learn the tools.
     The pump, fortunately, pumps :) Everything works! But ... the "bar" on the sensor jumps from 0.9 to 1 every 10-15 seconds.
     Yesterday they called a techie, said that everything was in order. Why is jumping? So this is due to the fact that your equipment is between two passes, in a draft, that is, that is, and, accordingly, there is a temperature difference.
     We are also thinking of calling a thread, just in case.
     What is your opinion about the jump?
     Thank you Oleg!

• #87

  Hello. Such a misfortune. The pumping station stopped sucking water. The valve was changed to zero. We put water in the hole –– from the 2nd turn on the mains - there is enough water and it works as usual. We close the pump, it is turned off. It turns off. It takes about 10 minutes and the song about the main thing .all on a new one. Even tried another station, the same song.

• #88

  Natalya, you have a water leak. Perhaps through a valve a can rupture in the pipeline.

• #89

  Hello. We bought a new Caliber 770 pumping station with an ejector, the well depth was only 9 meters, the water column in the well was about 1 meter, the suction hose was 2.5 cm. almost completely lowered to the end, at the end of the hose the check valve and after the mesh so as not to clog. The pressure in the receiver is 1.5-2.0. Voltage is about 225 V.
     The problem is that the pump works normally at the first start, but if it stands for a few minutes and it stops collecting water, the pressure drops to zero. Bleed the air from the top nut and add water to it. Water started, but the pressure dropped from 3.2 atm. up to 2.5 it was necessary to adjust the pressure switch so that the station shuts down. It takes 5-10 minutes and again the same story and the pressure drops lower and lower each time. Unscrew the suction hose, the water in it stands - the valve holds water. How much air can be vented from the pump and where does it come from.

• #90

  Judging by your description, you pump water out of the well, so the station has enough air and you have to top up all the time. Observe the water in the well at startup.

• #91

  Hello! Please tell me if the pumping station will work if the length of the suction line is 10 m, i.e. 6 m, the vertical pipe is lowered into the borehole and somewhere 4 m. It goes into the trench with a slight slope up to the stations. ? And tell me how to do the first run correctly! I tried to start something but didn’t get it, I poured water through the five-hole outlet, I like I got water completely, turned on the water a little bit, and all the stations were buzzing, there weren’t any valves, I disconnected the suction line, the valve seemed to keep water in the pipe, flooded again he turned on the same water, it’s possible that he didn’t let the air out and the system is airy, if so, how to do it right? Thanks in advance!

• #92

  Yuri, in the trench the pipe should be strictly horizontal. Water in the station must not be poured into the pyatnik but into the station itself, through the outlet pipe. To do this, install a crane with an American at the junction of the pipe with the station. See the diagram above in the article!

• #93

  Hello! I have such a problem: under the house there is a cellar (2m depth, normal ventilation does not rust), a station is installed in it. It worked without problems, on the weekend I decided to change the rubber outlet hose from the pyatnik to the tap for plastic universal software diameter 25. I turned off the station, drained the water from the tap, cut the hose, unscrewed the ruff from the pyatnik, soldered the wiring from the house too to 25 PP, connected everything to to cranes. When it came to an American who was screwed to a pyatnik, I saw that there was no water in it, I added it - it walks, then again and again, after another topping and tapping on the non-return valve, the water rose. I screwed an American, I turn on the station, the aon pumps 1.1 and then does not raise the pressure and does not turn off. I opened the faucet in the kitchen, opened the faucet at the exit of the station - I dumped water to 0.5 atm, closed the faucet, turned the station on for 5 seconds, turned it off - procedure was complete, there were no success in downloading. Everything is sealed on tow with paste. I decided that the check valve makes my brain replaced. How now to properly pump water and start the station? I don’t have a casing, a plastic hose 32 comes out of the ground and connects right away to an OK that is screwed to the station. If water is poured into this supply hose, then it naturally leaves and the column of water is not picked up. Please help in solving the problem.

• #94

  Many thanks! For advice, I obediently listen!

  I did not wait for an answer, changed OK, collected the feed and the station pumped water from about 5 times. But it can’t pump up pressure more than 1.8 atm (it’s already gone for the 5th year, probably something has worn out), by adjusting the relay, it has reached this limit, and turning on turned on at 1.5 atm, if you add a little it catches up to 2 atm and works but does not raise higher. What could break (wear out)? I would like to repair it myself at minimum cost to not change the whole motor. Thanks in advance who will respond.

  The pump buzzes, but will not turn on. If you turn the impeller, it starts to work. I cleaned the contacts, replaced the capacitor with a new one, when it needs to be pumped, it will buzz if it starts to work by turning the impeller, please tell me what could be the problem. thanks

  Timur, the impeller may wedge due to:
     1. Capacitor malfunctions
     2. Motor winding malfunctions
     3. Mains voltage too low.

  Dear website visitors! Many of you give very little information in describing the problem! In order to give at least some advice, you need to know:
     1. What pump or station?
     2. The immersion depth of the pump?
     3. Depth to a mirror of water?
     4. The amount of water in the well?
     5. Diameter of the suction line?
     6. Where is the receiver in the house or in the pit?
     7. What is the pressure in the receiver tank?
     8. What is the mains voltage?
     Questions like: "set the station and the water pressure is small, what should I do?" - will be deleted.

  Good afternoon, dear experts) I already wrote to you (
  ) It turned out to pump water but the hemorrhoid got out - with an empty tank, the station pumps water, but when the pressure drops and the station starts, it does not pump water and does not turn off until all water comes out of the tank. That is, I opened the water tap, the station turned on , the crane shuts the station, threshes it, opens the tap again, wait until the water runs out, then air is smoked and water goes again, you close the tap, the tank is pumped and the station turns off) these are the tricks. about 8 meters to the water in the pipe. there’s only one pipe 32. I’m tired of this already, as it’s a summer residence — they went without me — I arrive at the station threshing (it turned out already the second day) everyone smiles and don’t know what to do. called specialists, so they’re generally entertaining, they came, had a smoke, offered to hammer another well ... well, we sent them to hammer in another place. I will be very grateful for the good advice!)

  It looks like you have a bad flow of water into the well.

  when installing the station on the suction pipe, two corners first from the pump, the pipe goes down 30cm and then horizontally 60cm and then goes into the well at an angle of 90 degrees I can’t start the station; this may be the reason or the check valve does not work but keeps the water in the pipe

  the station crashed a couple of times: it worked, but did not pump water. disconnected. After a few minutes they turned it on, everything worked. but the next time she also began to buzz without taking water. After connecting to the network, the station does not turn on at all. sufficient voltage. What could be the reason?

• #103

  if the pumping station has run without water, the pump may deteriorate. does not build up pressure

  For Vova. Shock 101.
     Mav is absolutely analogous to the problem.
     As a rule, when you constantly turn on the cranes, you will have to repeat the operation and the need to operate the station in normal mode;

  Greetings, I have such a problem. The pumping station issued 3 atmospheres. Before replacing the non-return valve, there is now 1 atmosphere, what is the reason?

• #106

  Installed a station with a capacity of 1000. Clogged well pipe 32. only 10 meters. The level to the water is 4.5 meters. I installed a valve in front of the station, checked it was holding. I start the station, periodically release the air and add water; all the water goes; pressure 2 is turned off. Water is collected in a 10l bucket. in 20 seconds. In the morning I open the tap, 4 liters of water are drained, the pressure drops to zero and the station cannot raise water. And all over again, adding air release, already tired of everything, tell me why the malfunction.

  Alexey, everything is clear that the matter is in the check valve. Install valve with brass stem. It is necessary to check for leaks in the joints. Maybe you have a water leak somewhere?
     Eugene, most likely your check valve does not hold well, you need to check it and replace it if necessary.

  Is worth centrifugal pump  for the well. Water is flooded, the engine itself works, but does not pump. The hydraulic tank does not fill up either. What could be the problem?

• #109

  Hello. After replacing the pressure switch, my pump shakes jerkyly, often turns on and off, when the water is turned on, the pump turns off. What could be the problem here?

• #110

  Hello. pump station. I’ve pumped up atmospheres, I can live normally in the house, I can do it normally, but I can’t turn on the station until I’m quiet, I can’t stop it at all? replace relay?

  Hello. NS whirlwind worked for six months then it was turned off for a week and water does not go. I disconnected it, put it in the tank - it pumps ... in the well the level is kept ... pressure 1.5 - is ... but can the water not come from the pressure switch?

• #112

  The pump station switches on by itself every 5 minutes for 3-5 seconds, although all valves are closed. Pressure suddenly drops on the pressure gauge. Where to look for the reason, where to start?

• #113

  the turretless pressure does not turn off, pressure rushing to 6 and the relay does not cut down; the new engine also replaced the campaign today, the old one burned out in the morning for the same reason that maybe

  The Dzhileks water cannon 60/72, worked for about 3 years, stopped pumping, changed the capacitor and the electric motor in the service (supposedly water got into the engine). How to check the engine? It looks like a whole engine.

  I have a 750 watt taifu station. stopped downloading to the house. standing in a well, depth 4 m + to a mirror 9.4 m, pipe 32 lowered 2 m into water i.e. 11.4 from the pump to the well. Before that, she worked only a year and a half. The valve changed, the pipe changed, disassembled, everything inside is whole, put everything on the sealant. It only shakes at the mine itself and then jerks and bulbs slip through. During disassembly and inspection, I did not like the brass impeller; on it, the lateral vortex openings were as if flattened. Maybe because of this, the power fell. I connected only the top without a tank and hoses, but the result is the same. Need advice.

• #116

  Tell me, please. The problem is this: with the tap open, when all the water has flowed out. The water somehow ends, but the pump turns on only after a short time, you have to wait for the pump to connect and start pumping water again.

• #117

  Hello! the engine fires more often than before, changes the membrane, and if the station is disconnected from the network, the water leaves the pipe. and yet, how much do not pump, the pressure does not rise, but the pump works and pumps, only more often, the pressure is normal, what could be the reason?
