Staying outside the city, in a country residence, has additional difficulties, since centralized communications are not available everywhere. Residents of the periphery improve living conditions in a cottage or house so that it does not differ from urban comfortable housing. One of the points comfortable life concerns the constant availability of water in sufficient quantity. In this case, special equipment will help - a do-it-yourself pumping station. Due to self-installation you can save your family budget.
The main number of wells in summer cottages has a depth of up to 20 m - optimal for installing automatic equipment. With these parameters you do not need to purchase deep well pump, system automatic control or an intermediate container: water flows directly from the well (or well) to the collection points. To provide correct connection pumping station, you need to understand what it consists of and how it works.
The main functional units of the station are the following equipment:
- , ensuring the rise of water and its transportation to the house.
- A hydraulic accumulator that softens hydraulic shock. It consists of two parts separated by a membrane.
- Electric motor connected to pressure switch and pump.
- A pressure switch that controls its level in the system. If the pressure drops below a certain parameter, it starts the motor, if there is excess pressure, it turns it off.
- A pressure gauge is a device for determining pressure. It is used to make adjustments.
- A water intake system equipped with a check valve (located in a well or well).
- The main connecting the water intake and the pump.
Using this formula, you can determine the maximum suction depth: the diagram clearly demonstrates what measurements need to be made for this
The most common version of a pumping station is a hydraulic accumulator with a surface pump and a unit including a pressure gauge, pressure switch and dry-running protection
As can be seen from the table, the cost of pumping stations can vary. It depends on the power, maximum pressure, bandwidth, manufacturer
Before installation pumping equipment it is necessary to purchase all functional parts according to the well parameters and plumbing system.
Self-installation of a pumping station
At first glance, there are quite a lot of places for installing equipment - this is any free corner in the house or outside it. In reality, everything turns out to be different. However, only a well-thought-out installation of a pumping station guarantees its full operation, so some conditions must be observed.
Installation conditions:
- proximity to a well or well ensures stable water absorption;
- the room must be warm, dry and ventilated;
- the location should not be cramped, as maintenance and repair work will be required;
- the room must hide the noise produced by the pumping equipment.
One option for installing a pumping station is on a shelf specially attached to the wall. The installation room is a boiler room, boiler room or utility room.
It is difficult to comply with all the conditions, but it is advisable to adhere to at least some. So let's look at a few suitable places for installation.
Option #1 – room inside the house
A well-insulated boiler room on the territory of the cottage is an ideal area for installation in case of permanent residence. The main disadvantage is good audibility with poor sound insulation of the room.
If the pumping station is located in a separate room country house, then it is best to install a well directly under the building
The material on how to make a well water supply system will also be useful:
Option #2 – basement
Underfloor or basement can be equipped for installation of a pumping station, but this should be considered during design. If there is no heating in the room, and the floors and walls are not insulated, you will have to spend a lot of effort to prepare it.
A well-equipped basement is ideal for installing a pumping station. When laying a pipeline, a hole for communications should be made in the foundation of the house.
Option #3 – special well
A possible option that has a couple of pitfalls. The first is the difficulty of maintaining the required level of pressure in the house, the second is the difficulty of carrying out repair work.
When the pumping station is located in a well, on a specially equipped site, the pressure level should be adjusted, which depends on the power of the equipment and the parameters of the pressure pipe
Option #4 – caisson
A special area near the well exit is also suitable for installation, the main thing is to correctly calculate the depth of its location. Required temperature will create warmth of the earth.
Pumping station, located in the well caisson, has two advantages: complete noise insulation and protection from freezing during frosts
In the absence of specially designated places, install the unit in places common use(in the hallway, bathroom, corridor, kitchen), but this is a last resort. Loud station noise and comfortable stay- these are incompatible concepts, so it is better to prepare a separate room for installing a pumping station in a dacha.
Pipeline laying
The well is usually located near the house. In order for the pumping station to operate properly and without interruptions, it is necessary to ensure the unhindered flow of water from the source to the equipment, which is located in a specially designated area. For this purpose, a pipeline is laid.
Low winter temperatures can cause pipes to freeze, so they are buried in the ground, preferably to a depth below the ground freezing level. Otherwise, the line should be insulated. The work boils down to the following:
- digging a trench with a slight slope towards the well;
- making holes in the foundation for pipes optimal height(if necessary);
- pipe laying;
- connecting the pipeline to pumping equipment.
During the construction of the highway, you may encounter such a problem as the presence of high-standing surface waters. Pipes in in this case mounted above a critical level, and used to protect against cold heat insulating material or heating cable.
Advantages polyethylene pipes and fittings over metal analogues: no corrosion, ease of installation and repair, low price (30-40 rubles/linear meter)
This pumping station installation diagram shows an option for insulating pipes above the ground freezing level
The best option for thermal insulation of external water pipes is a solid “shell” of polystyrene foam (8 cm thick) wrapped in foil
For thermal insulation of pipes that are laid above the ground freezing level, inexpensive and environmentally friendly pure material – mineral wool on a basalt basis.
Exterior works
WITH outside polypropylene pipe we attach a metal mesh that will serve as a filter rough cleaning. In addition, you will need a check valve to ensure that the pipe is constantly filled with water.
It is possible to purchase a ready-made hose with a check valve and a coarse filter, but equipped with your own hands will cost much less
Without this part, the pipe will remain empty, therefore, the pump will not be able to pump water. We fix the check valve using a coupling with external thread. The end of the pipe equipped in this way is placed in the well.
The coarse filter for the supply hose is a metal mesh with a fine mesh. Without him correct work pumping station is not possible
After completing these steps, you can start upgrading the well head.
Connecting equipment
So, how should you properly connect your home pumping station so as not to encounter technical inconsistencies in the future? First of all, we install the unit on a specially prepared base. It can be brick, concrete or wood. To ensure stability, we screw the legs of the station using anchor bolts.
For installation of the pumping station, special legs-stands are provided; however, to provide additional stability, the equipment must be fixed with bolts
Placing a rubber mat under the equipment can help dampen unnecessary vibrations.
For more convenient maintenance, the pumping station is installed on a base with a height of regular table made of durable material - concrete, brick
The next step is to connect the pipe coming from the well. Most often this is a polyethylene product with a diameter of 32 mm. For connection you will need a coupling with an external thread (1 inch), metal corner with external thread (1 inch), check valve with the same diameter, straight American tap. We connect all the parts: we secure the pipe with a coupling, and we fix the “American” with a thread.
One of the check valves is located in the well, the second is mounted directly to the pumping station. Both valves serve to protect the system from water hammer and provide right direction water movement
The second output is intended for communication with water supply network. It is usually located at the top of the equipment. The connection pipes are also made of polyethylene, as it is inexpensive, flexible, durable material. Fixing occurs in a similar way - using an “American” and a combined coupling (1 inch, angle 90°) with an external thread. First, we screw the “American” to the outlet of the station, then we install a propylene coupling into the tap, and finally we fix the water pipe in the coupling using the soldering method.
To completely seal the connections, they must be sealed. Traditionally, a winding made of flax is used, and a special sealing paste is applied on top of it.
After you have connected the pumping station to the water intake and plumbing system, you need to check the quality of its operation.
We are conducting a test run
Before starting the station, it must be filled with water. We let water through the filler hole so that it fills the accumulator, lines and pump. Open the valves and turn on the power. The engine starts and water begins to fill the pressure pipe until all the air is removed. The pressure will increase until the set value is reached - 1.5-3 atm, then the equipment will automatically turn off.
In some cases it is necessary to adjust the pressure value. To do this, remove the cover from the relay and tighten the nut
As you can see, installing a home pumping station with your own hands is not at all difficult; the main thing is to follow the installation instructions.
One of the first engineering systems, which are created in private households, is a water supply system. Its use is necessary at the construction stage. Without a plumbing system, it is impossible to fully live in a house around the clock. Modern houses have in their composition utility networks not only ordinary water taps, but also automatic devices that use water. In order to have water pressure in your home around the clock, each owner needs to know how to connect a pumping station.
What is a pumping station?
During construction autonomous system water supply and connecting the water supply of a private house to the main utility networks, every owner wants to receive a constant water pressure in the system. So, to lift water from a well or from a location located on personal plot well, you can use pumping devices. They are various models and power, can be located in different segments of the water supply system. Submersible pumps are lowered directly into a well or well, while surface pumps are placed at ground level, drawing water through an inlet hose.
The pump should not run continuously. Continuous operation leads to rapid wear of the components and mechanisms of this device. At the same time, do you want to use water at any time of the day? There is a solution: to ensure constant pressure in the pipelines of the water supply system, a pumping equipment station is assembled.
Main parts of the pumping station
- N asos. Typically, a set of stations uses surface pumps, which draw water from a well, borehole or main network through an inlet pipe with a filter.
- Pressure accumulator or hydraulic accumulator. It is usually a container certain size, inside of which there is an elastic rubber partition or internal container. When the pressure increases, the system container or partition expands, and when the pressure decreases, it contracts, squeezing water into the system and maintaining constant pressure parameters.
- Control node, which determines when to turn on pumping device, and when should he stop working. The on and off parameters are determined by the pressure in the system, which is measured by a pressure gauge.

Options for installing a pumping equipment station
Pumping equipment stations, regardless of the location of the water source, can be installed in three main places.
Features of choosing a location for a pumping station
Connection options for pumping equipment station
Depending on the configuration of the water supply system, you can choose one-pipe and two-pipe connection schemes for the pumping equipment station. Two-pipe system used to increase the depth from which a pumping station can lift water.
The single-pipe scheme is used for well depths not exceeding 10 meters. If it exceeds 20 meters, then it is preferable to use a two-pipe circuit with an ejector.
Connecting a pumping station (two-pipe scheme)
On initial stage The ejector is assembled, which is a separate unit made of cast iron, with three outlets for connecting the pipeline.
- First, we install a filter mesh on the ejector (in its lower part), which protects the pumping equipment from failure when small stones or sand enter from a well or well.
- A plastic socket is mounted in the upper part of the ejector assembly, to which a squeegee with a cross-section of 3.2 cm is attached. You may have to mount several squeegees at the same time in order to reach the cross-section of the water pipe.
- At the end of the run, we install a coupling that will ensure the transition to a plastic pipeline. Typically such a coupling is made of bronze.
When connecting elements, pay attention Special attention for tightness of connections. Of course, a leak in a well or borehole will not cause you any aesthetic inconvenience, however, air intake in leaky connections can lead to instability in the operation of the system and a significant reduction in its power. Threaded connections sealed with special paste, fum tape, linen winding or rubber gaskets.
Remember! Water supply pipelines must either pass below the soil freezing depth or be properly insulated.
When introducing water supply pipes into a caisson or another location where a pumping equipment station is installed, it is necessary to provide them with some reserve in length. After removing the pipes, we begin to connect the pumping equipment station to the pipelines from the well.
- We install the head on the casing pipe of the drilled well.
- We find out the depth of lowering the pipes into the water well. To do this, lower any solid long object into the drilled shaft. The level of placement of the inlet pipe of the pumping equipment station should be approximately a meter away from the bottom of the well, so as not to suck in sand, silt or stones from the bottom.
- We attach polyethylene pipes to the ejector unit. The length of the pipe should be equal to the sum of the distance from the wellhead to the pump and the depth of the well (minus one meter).
- We mount an elbow at the well head with a 90-degree rotation.
- We push it through the straight knee plastic pipes leading to the ejector unit (after installation is completed, the space between the inside of the elbow and the pipelines can be filled polyurethane foam). In a straight elbow, the pipes can be either bent or connected by adapters with a rotation angle of 90 degrees.
- We lower the ejector device to the required depth. You can check the correct installation depth of the ejector using the mark we previously made on the pipeline.
- We fix a homemade head on the top of the casing, which consists of a pipe bend turned at an angle of 90 degrees. You can secure the “head” to the well casing using specialized tape for plumbing fixtures with reinforcement.
We bring water pipes to the house. You may have to provide turns. The entrance of water pipes through the foundation must be located below the soil freezing line. The removed pipes are connected to the water pipe of the pump as part of the station. The pipelines are connected using a wrench or an adjustable wrench.
There is usually a filler hole on the top of the pump as part of the equipment station. It is necessary so that it does not start “dry”. Filling with water is carried out only during the initial start-up or when starting up after a long period of inactivity.
Before starting the pumping equipment station, check the operating pressure in the hydraulic accumulator. Usually it is 1.2 - 1.5 atmospheres. You can increase the operating pressure using a regular car pump. For pumping up pressure accumulators in water supply systems there is a special nipple.
How to connect a pumping equipment station to the main water supply
Sometimes it is necessary to connect a pumping equipment station not to a well or well, but to the main water supply. This is relevant when connecting to utility networks with low or unstable pressure. You can make such a connection in the following sequence.
We regulate the operation of the pumping equipment station
After installing the connecting elements, the system must be run in test mode to check the tightness and functionality of all its segments. Before starting, water is poured into the filling hole of the pumping equipment station, this prevents the device from running dry.
As a rule, all adjustment parameters are set at the station before it is launched, based on the calculated parameters of the house’s plumbing system. During operation, the working components of the pumping equipment station may wear out, so it is advisable to carry out additional adjustments of the pump operating parameters approximately once a year. Precise adjustment of the pumping equipment system with built-in pressure accumulators is carried out own block automation.
An important nuance. All pumping equipment stations include Electrical engine. He may have more power, therefore we recommend that you provide such a station with its own power supply line. power line The station will operate in a humid environment, so take care to install protected sockets and lay cables in special corrugated tubes.
As you can see, connecting a pumping equipment station is accessible even to a non-professional with minimal technological skills. Its installation will help you ensure uninterrupted water supply to your home and garden.

Most often you can find water towers of the Rozhnovsky system, made according to standard project. Rozhnovsky towers with a capacity of 15, 25, 50 m 3 provide water supply to small settlements, plants and factories, railway stations, livestock and poultry complexes, MTS, etc.
Rozhnovsky’s successful design from the 30s of the last century, which still serves faithfully to this day, includes an overflow pipe as an element of minimal automation that prevents the tower from overflowing. With visual monitoring of overflow, it is still impossible to avoid the loss of artesian water and, accordingly, the energy spent on its rise.
Modern automation tools make it possible to control the water level in the tower and timely turn on and off the pumps, ensuring their safe work, energy saving, etc. But, often, no matter how paradoxical it may be, the user who has equipped water tower modern means automation, continues to rely on the overflow pipe as the ultimate remedy for overflow. Obviously the problem is refusal automated systems, mainly level control devices. The consequences of inactivity of the level control system, including the overflow pipe itself, can sometimes be seen in winter in the form of a huge ice hanging from the water tower.
Having a fairly wide market supply level control devices, the question arises about making the right choice level sensor.
Offered:
- Float sensors (sliding along the rod, inclined, floating suspended);
- Capacitive sensors embedded in the tank wall;
- Capacitive sensors embedded in the tank lid
- Non-contact ultrasonic sensors;
- Conductive sensors;
- Hydrostatic level sensors;
- Hydrostatic pressure sensors.
Perhaps, you can immediately reject sensors installed by inserting into the wall of the tank due to ice that forms in winter on the inner walls of the support and tank, the thickness of which can reach 30 cm and serve as a natural heat insulator in Rozhnovsky’s unheated tower. This capacitive sensors, second on the list.
Next are conductive sensors, fifth on the list. As the temperature drops, the conductivity of water decreases greatly, and when light icing appears on the metal probe of the conductive sensor, its sensitivity is reduced to zero, because ice is a dielectric.
Particular attention should be paid to sensors that are installed on top: on the roof or under the roof of the tower. To install them, it is necessary to run the cable upward, taking measures to prevent breakage due to icing, gusts of wind, mechanical and other influences. If all conditions are met, the fourth non-contact ultrasonic liquid level gauges on the list can function normally, but only those that guarantee stability at temperatures below 0C. Ultrasonic sensors, among others mentioned here, are expensive.
Capacitive sensors embedded in the roof of the tank. To control the upper and lower levels, you will need two sensors in compliance with the rules for laying the cable upward. The sensors have long probes; To monitor the lower level, you will need a probe corresponding to the height of the tank. Price this decision quite high, approaching or even exceeding the cost of the ultrasonic method.
From float sensors The pop-up type works, but it also freezes, especially the sensor top level, when the float is free at low water.
Level gauges of this type are also used for continuous measurement of medium pressure. The main tasks solved with the help of these level meters: Assessment of the level of liquids in large stationary storage tanks.
The current control relay is designed to convert a 4...20mA input signal into a relay output signal.
The device is an intelligent relay for level monitoring and pump control tasks. Using the “teach-in” function, it is possible to “remember” two level values in the current range 4...20 mA, and also assign one of the programmed modes to control the output relay contact. To turn the pump on and off for filling using two-level logic, the Switching Difference mode is provided.
A pumping station is excellent equipment that allows you to automate the process of drawing water from a well. Complex technical devices activates the launch of the system when necessary to replenish supplies and turns off the units at the right time. The level of comfort will increase incredibly. After all, even outside the city it is necessary to enjoy the achievements of civilization, don’t you agree?
However, it is not enough to just buy incredibly useful equipment; you need to know how to install and connect it. We invite you to read the article, which covers all the issues in great detail. This information will be useful to all owners of suburban housing, no matter whether the pumping station is connected with their own hands or hired workers are invited to install it.
In our article you will get acquainted with the types of pumps used in intake systems groundwater. Also here are all possible options equipment location and connection to autonomous water supply. The information is supported by diagrams, photo materials and videos.
The pumping equipment station performs two functions at once - it supplies water to the water supply system of the house and automatically maintains the set pressure in it.
This allows you to lay an extensive water supply network and connect household appliances to it - a shower cabin, a boiler, a dishwasher and a washing machine.
A typical station design includes:
- Pump;
- Hydraulic accumulator;
- Automation block;
- Input strainer– necessary to prevent particles of impurities and possible contaminants from entering the system;
- Pipelines, hoses and necessary fittings.
To prevent the outflow of liquid from the system when the pump stops or the pressure decreases, a check valve is installed in the water intake area. A source of water intake is also required. For this purpose, a well or borehole is constructed.
It is possible to use a reservoir (pool) with imported water and open reservoirs if the characteristics of the unit allow pumping contaminated liquid.

Types of pumps used
In the home water supply system it performs the following functions:
- Protects the pump from wear and increases its service life - thanks to the liquid reserve in the membrane compartment, the number of unit starts is significantly reduced.
- Maintains constant pressure in the water supply and protects against pressure changes.
- Eliminates the occurrence of water hammer in the system, destructively affecting connected devices and pipeline fittings.
- Provides some water supply in case of power failure.
The device is a sealed vessel, the internal volume of which is divided into two containers by an elastic membrane. One of them is filled with air, and the second is intended for pumping water.
The hydraulic tank works as follows. Water is pumped into an elastic container until the upper pressure threshold is reached. The pump then turns off.
The pressure in the system is maintained by air gap in a hydraulic accumulator, compressed air plays the role of a damper. When the volume of water decreases (consumed by consumers) and the pressure reaches the lower set limit, the pump turns on again and fills the hydraulic tank with water.
A hydraulic accumulator is selected based on calculations that take into account the number of residents, the number of water consumption points, the maximum permissible number of pump starts and its power, and the required pressure in the system.
Insufficient working volume of the tank will lead to constant activation of the pump and its wear. A container with a reserve threatens water stagnation and a decrease in its quality, harmful effects on the inner surface of the membrane.

In other cases, the system elements are installed independently. When installing a surface station, a pipeline (or two pipelines, if a remote ejector is used) from the well is connected to the pump.
Next, install the hydraulic accumulator and control unit. For a station with borehole pump these will be all the main surface elements in the circuit. It is most convenient to use a 5-pin fitting for this, which is mounted in the pressure pipeline in convenient location. A pressure switch and pressure gauge are screwed into it.
A hydraulic accumulator is connected to the side entrance of the fitting. For ease of maintenance, it is connected through a ball valve with an American connection and a drain is arranged.
Connect consumers to the pumping station. Most often, the first element is the cold water distribution manifold.
Step #5 – first launch of the station
The electric motor of the pump has more power, so it is better to provide the pumping equipment station with its own power supply line, arrange grounding and install a voltage stabilizer.
Check the pressure of the air chamber of the hydraulic accumulator. It should be 10% less than the pump activation pressure. However, this setting is done in operating mode. First, it is necessary to achieve the following values: for a hydraulic tank with a capacity of 20-30 l - 1.4...1.7 bar, with a capacity of 50-100 l - 1.7...1.9 bar.
Before starting the installation with a surface pump for the first time, the working part of the system is filled with water. To do this, unscrew the plug from the filler hole located in the upper part of the pump.
If the pipeline has a filler funnel, it is better to use it. Pour in liquid until it is completely filled and begins to flow out. Then the hole (valve) is tightly closed.
Startup sequence:
- The pump is connected to the mains.
- The valve of the filling funnel of the pipeline with a surface pump is opened slightly to remove any remaining air that has entered the system.
- Turn on the unit - within 2-3 minutes water should flow from the outlet of the pressure pipeline (or an open water supply tap).
- If the liquid does not flow, the pumping equipment is turned off, water is added to the system and turned on again.
After a successful start, the equipment should be “run in” and, if necessary, the settings of the valve body and pressure switch should be adjusted.
Basic operating rules
After putting the pumping station into operation, periodic maintenance is carried out. It is necessary to clean the coarse filter promptly. Without this, the performance of the installation gradually decreases, the water is flowing jerkily, and a completely clogged filter will lead to “dry” operation and shutdown the system.
The frequency of purification depends on the content of impurities in the pumped water.
You can read information about common pumping station breakdowns and how to fix them in the following article
How to make a pumping station based on a submersible pump:
Correct installation of the pumping station ensures a private house water supply with parameters not inferior to a city apartment - constant pressure and sufficient pressure.
In order for the system to operate as efficiently as possible, before selecting and installing equipment, you should seek advice from a specialist and perform an evaluation calculation.
If you have experience self-assembly and installation of a pumping station, please share your knowledge in the comments to this article. If you have any questions after reading the material, do not hesitate to ask them in the comments below.
Individual water supply for a private house or cottage can be from two sources - or a well. To automate the supply of water to the house, as well as to create stable pressure, it is necessary to install a pumping station. It consists of a pump and a safety group (pressure gauge and drain valve). The advantage of this idea is that with such a water supply scheme any Appliances, another good news is that the connection is not too difficult task, if desired, you can install and connect the pumping station with your own hands.
Choosing an installation location
Pumping stations are installed near a water source - a well or a well - in a specially equipped pit - a caisson. The second option is in utility room in the house. The third is on a shelf in the well (this number will not work with a well), and the fourth is in the underground.
Installing a pumping station in the underground - the noise from its operation may be too audible
How to Determine Suction Depth
When choosing a location, they are primarily guided by the technical characteristics - the maximum suction depth of the pump (from where the pump can lift water). The thing is that the maximum lifting depth of pumping stations is 8-9 meters.
Suction depth - the distance from the water surface to the pump. The supply pipeline can be lowered to any depth; it will pump water from the level of the water surface.
Wells often have a greater depth than 8-9 meters. In this case, you will have to use other equipment - submersible pump or a pumping station with an ejector. In this case, water can be supplied from 20-30 meters, which is usually sufficient. The disadvantage of this solution is expensive equipment.
Suction depth is a characteristic that determines the installation method
If you are just a meter short of being able to install conventional equipment, you can install the station in a well or above a well. In the well, a shelf is attached to the wall; in the case of a well, the pit is deepened.
When making calculations, do not forget that the water level “floats” - in summer it usually drops. If your suction depth is on the verge, there may simply be no water during this period. Later, when the level rises, water supply will be restored.
Security Considerations
Another point that must be taken into account is the safety of the equipment. If the installation of a pumping station is planned near a house with permanent residence, there are fewer problems - you can choose any option, even in a small shed. There is only one condition - it should not freeze in winter.
If this is a dacha where people do not live permanently, the matter is more complicated - you need to arrange a room that does not catch the eye. Most safe way installation of a pumping station - in the house. Although they can take it away in this case too.
The second place where you can install a pumping station is a buried camouflaged caisson.
The third is on a shelf in the well. Only in this case it is not worth doing the traditional one. You need a steel lid that can be locked with a reliable lock (weld hinges to the ring, make slits in the lid on which to hang the locks). Although, a good cover may also be hidden under the house. Only the design needs to be thought out so that it does not interfere.
Convenience and operating conditions
Installing a pumping station in the house is good for everyone, except that the equipment is noisy during operation. If there is a separate room with good sound insulation and technical specifications it's possible - no problem. Often they make a similar room in the basement or in ground floor. If there is no basement, you can make a box in the underground. Access to it is through the hatch. In addition to sound insulation, this box must also have good thermal insulation— operating temperature range starts from +5°C.
To reduce the noise level, the station can be placed on thick rubber to dampen vibration (created by the cooling fan). In this case, it is even possible to install it in the house, but the sound will certainly still be there.
If you choose to install a pumping station in a caisson, it should also be insulated and also waterproof. Usually, ready-made reinforced concrete containers are used for these purposes, but a caisson can be made from concrete rings(type of well). Place the ring with the bottom down, and the ring with the lid on top. Another option is to build it out of brick and fill the floor with concrete. But this method is suitable for dry areas - the groundwater level should be one meter below the depth of the caisson.
The depth of the caisson is such that the equipment is installed below the freezing level. Insulation foam polystyrene. Better - extruded. Then at the same time you also get waterproofing.
For a caisson made of concrete rings, it is convenient to use a shell (if you find a suitable diameter). But it is also possible slab polystyrene foam, cut into strips and glue it. For rectangular pits and structures, slabs are suitable, which can be glued to the walls using bitumen mastic. Coat the wall, apply insulation, you can additionally secure it with a pair of nails/dowels.
Connecting the pumping station
Selecting equipment and installation location is only half the battle. You also need to correctly connect everything into the system - the water source, the station and the consumers. The exact connection diagram of the pumping station depends on the selected location. But in any case there is:
- A suction pipeline that is lowered into a well or well. He goes to the pumping station.
- The station itself.
- Pipeline going to consumers.
All this is true, only the strapping patterns will change depending on the circumstances. Let's look at the most common cases.
Water supply from a well for permanent residence
If the station is installed in a house or in a caisson somewhere on the way to the house, the connection diagram is the same. A filter (most often a regular mesh filter) is installed on the supply pipeline lowered into a well or borehole, a check valve is installed after it, and then the pipe goes. Why a filter is understandable - for protection against mechanical impurities. A check valve is needed so that when the pump is turned off, water does not flow back under its own weight. Then the pump will turn on less often (it will last longer).
The pipe is led out through the wall of the well at a depth just below the freezing level of the soil. Then it goes into a trench at the same depth. When laying a trench, it must be made straight - the fewer turns, the lower the pressure drop, which means that water can be pumped from a greater depth.
To be sure, you can insulate the pipeline (lay polystyrene foam sheets on top, and then cover it with sand, and then with soil).
Option of passage not through the foundation - heating and serious insulation are required
At the entrance to the house, the supply pipe passes through the foundation (the passage place is also insulated); in the house it can already rise to the installation site of the pumping station.
This method of installing a pumping station is good because if everything is done correctly, the system works without problems. The inconvenience is that it is necessary to dig trenches, as well as to remove/introduce the pipeline through the walls, and also that when a leak occurs, it is difficult to localize the damage. To minimize the chances of a leak, take proven quality pipes and lay a whole piece without joints. If there is a connection, it is advisable to make an inspection well.
There is also a way to reduce the volume earthworks: lay the pipeline higher, but insulate it well and use it additionally. This may be the only way out if there is high level groundwater.
There is one more important point- the well cover must be insulated, as well as the outside rings to the freezing depth. It’s just that the section of the pipeline from the water surface to the outlet into the wall should not freeze. This is why insulation measures are required.
Connecting the pumping station to the water supply
Often the pumping station is installed at centralized water supply. In this case, connect to the station input water pipe(also through a filter and check valve), and the output goes to consumers.
It is advisable to install a shut-off valve (ball valve) at the entrance so that, if necessary, you can turn off your system (for repairs, for example). The second shut-off valve - in front of the pumping station - is needed to repair the pipeline or the equipment itself. Then it also makes sense to install a ball valve at the outlet - so that, if necessary, cut off consumers and not drain water from the pipes.
Well connection
If the suction depth of the pumping station for the well is sufficient, the connection is no different. Is it just that the pipeline exits at the place where it ends casing. A caisson pit is usually installed here, and a pumping station can also be installed here.
Installation of a pumping station: connection diagram to a well
As in all previous schemes, a filter and check valve are installed at the end of the pipe. At the inlet you can install a filler valve through a tee. You will need it the first time you start.
The main difference between this installation method is that the pipeline to the house actually runs along the surface or is buried to a shallow depth (not everyone has a pit below the freezing depth). If the pumping station is installed at the dacha, it’s okay; the equipment is usually removed for the winter. But if the water supply is planned to be used in winter, it must be heated (with a heating cable) and insulated. Otherwise it won't work.
Start-up of the pumping station
In order to put the pumping station into operation, it and the supply pipeline must be completely filled with water. For this purpose, there is a special filler hole in the housing. Pour water into it until it comes out. We screw the plug into place, open the tap at the outlet to the consumers and start the station. At first, the water comes with the air - they come out air jams, which were formed when filling the pumping station. When water will flow smooth stream without air, your system has entered operating mode, you can operate it.
If you have added water, but the station still does not start - the water does not pump or flows in jerks - you need to figure it out. There are several possible reasons:
- No check valve on the suction pipeline lowered into the source, or it does not work;
- somewhere on the pipe there is a leaky connection through which air leaks;
- The resistance of the pipeline is too high - a pipe of a larger diameter or with smoother walls is needed (in the case of a metal pipe);
- The water level is too low, there is not enough power.
To prevent damage to the equipment itself, you can start it by lowering a short supply pipeline into some kind of container (water tank). If everything works, check the line, suction depth and check valve.
