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 of a comfortable life concerns the constant availability of water in sufficient quantities. In this case, special equipment will help - a do-it-yourself pumping station. By installing it yourself, 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, there is no need to purchase a deep-well pump, an automatic control system or an intermediate tank: water flows directly from the well (or well) to the collection points. To ensure proper connection pumping station, you need to understand what it consists of and how it works.

Main functional units station is 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 mounted on top and a unit that includes 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 installing pumping equipment, it is necessary to purchase all functional parts according to the parameters of the well and water supply 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 several suitable installation locations.

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 of a country house, then it is best to install the well directly under the building

The material on how to make a well water supply system will also be useful:

Option #2 – basement

An underground or basement room can be equipped for the installation of a pumping station, but this should be considered during the 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. The required temperature will be created by the heat of the earth.

The 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. The loud noise of the station and comfortable rest are incompatible concepts, so it is better to prepare a separate room for installing a pumping station in the country.

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;
installing a hole in the foundation for the pipe at the optimal height (if necessary);
pipe laying;
connecting the pipeline to pumping equipment.

During the construction of the highway, you may encounter a problem such as the presence of high-standing surface water. In this case, the pipes are installed above the critical level, and heat-insulating material or a heating cable are used to protect against cold.

Advantages of polyethylene pipes and fittings over their metal counterparts: lack of 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– basalt-based mineral wool.

Exterior works

We attach a metal mesh to the outside of the polypropylene pipe, which will serve as a coarse filter. 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 an 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 it, proper operation of the pumping station is impossible

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

If you place it under the equipment rubber mat, you can dampen unnecessary vibrations.

For more convenient maintenance, the pumping station is installed on a base the height of a 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. To connect, you will need a coupling with an external thread (1 inch), a metal angle with an external thread (1 inch), a check valve with the same diameter, and a 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 ensure the correct direction of water movement

The second outlet is intended for communication with the water supply network. It is usually located at the top of the equipment. The connection pipes are also made of polyethylene, as it is an 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.

If you are planning to live in a private house or in a comfortable country house, then you should undoubtedly be interested in the issue of an autonomous water supply system. Not in every way cottage village or the private sector, and even more so in the dacha society there is centralized system water supply Public utilities, presented by third-party companies, “bite” strongly.

A full-fledged water supply system on a personal plot must include a pumping station, which can be assembled with your own hands, without the involvement of third-party craftsmen. Self-installation of such equipment will significantly save your family budget.

Why is a pumping station needed in a water supply system?

The autonomous source of water supply in the vast majority of household plots is a well. P , we will look at in our article. It can be of varying depths, depending on the level of the aquifer, but usually a shaft is drilled to a depth of at least 20 meters to avoid contaminated surface groundwater entering the water supply system.

Water is lifted from a well of this depth using a pump. But for a complete autonomous water supply system, one pump and the pipelines connected to it are not enough. The pump cannot and should not work constantly, as its components and mechanisms will become unusable after quite a while. a short time. To ensure an uninterrupted supply of water to all water points in your home, it must have a pumping station - a set of equipment that allows you to use water around the clock and at any time of the year.

Composition of pumping station equipment

In order to raise water from a well you need pumping device. It can be of various designs and placements, for example, surface (taking up water through an inlet pipe lowered into the well) or submersible (located directly in the well, at the level of water occurrence and pushing it to the surface), working using the centrifugal or vibration method. Almost all pumping devices for autonomous water supply are powered from the electrical network.

The next element of the pumping station is pressure accumulator or hydraulic accumulator. It ensures constant water pressure in water supply pipelines. The classic version of a pressure accumulator is a steel tank divided into two parts by an elastic rubber partition. When the pumping device operates, water fills part of the tank, tensioning the membrane. When the pumping device is turned off, the membrane, trying to return to its original position, pushes water into the water supply. In addition to ensuring constant water pressure in the system, the pressure accumulator protects it from water hammer - a sudden change in pressure parameters in pipelines.

The moments of turning on or off the pumping device are determined automation unit - control relay, which is triggered depending on the pressure in the pipelines. When the pressure in the water supply pipeline system drops below a certain value, the unit turns on and water fills the pressure accumulator, tensioning the membrane. When the set pressure parameters are reached, the relay is activated and the pump is turned off.

All components of the pumping station are interconnected pipelines, with which the equipment is connected to the input circuit of the home water supply.

The most common configuration of a pumping station in a private home is a combination of a surface pumping device with a pressure accumulator and control equipment.

The price of ready-made pumping stations can vary within quite a wide range. By purchasing all the components separately and installing them yourself, you can save a lot of money.

How to install a pumping station yourself?

On initial stage it is necessary to correctly calculate all the parameters of the future water supply system. The starting point for this calculation will be three values.

Well production- the amount of water that a pumping device is capable of pumping out of it in a certain period of time.
Water consumption parameters– the number of people permanently living in the house, the number of appliances and equipment that consume water (for example, an automatic washing machine or dishwasher). Naturally, this parameter cannot in any way be greater than the first one, but there are situations when a well has an excess flow rate that is simply not needed for use in a particular house. When calculating water consumption parameters, do not forget to seasonal work, for example, summer watering of crops or engineering works, for example, washing your car regularly.
In addition, when choosing equipment for a pumping station, such a characteristic as and house configuration. The purchased and installed equipment must have power and pressure sufficient to lift water from the lowest point of the well to the highest point of water intake in the house.

Thus, having calculated all the parameters of water intake and water consumption, you purchase all the main components of the pumping station and begin their independent installation.

Prices for a pumping station

Where should the pumping station be located?

In order for your pumping station to ensure constant delivery of water with specified pressure parameters to any point in the house, its location must meet the following requirements:

be located sufficiently close to the source of water supply so that the pumping device can operate reliably at all times;
have comfortable temperature conditions, so that work at subzero temperatures does not damage equipment components;
the place where the pumping station is located must be accessible for preventive maintenance and repair work.

The most suitable place for installing a pumping station in a private house, based on such requirements, is either a specially built caisson, or a special room or part of it in the basement of the house, or in outbuildings.

Let's consider all the pros and cons of installing pumping stations in various places.K , you can read in our article.

When the pumping station is located indoors inside a private house you get ideal access to the equipment, but if the noise insulation is poor, the operation of the equipment will cause you discomfort. But if the well is located directly under the house, then best option can not found. When choosing such a location, you should take into account that the room should be warm, or better yet, heated. In principle, a separate room in the insulated basement of a private house is one of the ideal options.

An option for location in the house is to install a pumping station in a separately located outbuilding. In this case, you will not be able to quickly access the equipment, but you will be spared noise problems. When separating the production segment from the consumption segment, it is necessary to pay special attention to the laying of the water supply pipeline. It must be located below the freezing level of the soil, or sufficiently insulated to prevent freezing of water in the pipes in winter.

One of the traditional locations for a pumping station is a caisson - a special container located directly on a personal plot above the location of the well head. Caisson It can be either a permanent structure made of monolithic concrete or brickwork, buried in the ground, or a steel or plastic container, also buried in the ground with its lower part below the freezing level of the soil. However, this method of placement is fraught with difficult access to equipment. Also in this case, it is necessary to insulate or sufficiently deepen the water pipeline leading to the house or to other points of consumption.

How to install a pumping station yourself?

So, we have figured out the composition and location of the pumping station, now it’s time to start installing it.

Step 1

To ensure that the station does not experience unnecessary vibrations during operation, it must be secured to a solid base. One of the options for constructing such a base is a solid concrete slab. You can choose a ready-made option, or you can fill the base for the pumping station yourself. The technology for pouring the foundation generally coincides with the algorithm for pouring slab foundations. A thickness of 10-15 centimeters will be quite enough for such a base.

A sand cushion is poured into the prepared shallow pit. Then a reinforcing frame is made of metal rods, which are tied together. On the sides, the area of the future base is limited by boards or chipboard scraps. After pouring, the concrete will mature for several weeks.

Also, the base for the pumping station can be laid out of bricks. Two layers placed on a compacted sand bed will be sufficient.

The pumping station can also be placed on a strong wooden panel made from beams, but in this case it is necessary to provide for the placement of shock-absorbing rubber pads. The thickness of the bars must be at least 10 centimeters. The base of the pumping station should extend approximately 10 centimeters beyond the perimeter of the equipment.

Step 2

We place the pumping station equipment on the prepared site. When installing a station from ready-made units, you should not have any special problems. It is worth paying attention to the cross-section of the pipelines connecting the elements of the pumping station and their correct fastening.

Simply place the pumping device, pressure accumulator and control unit on the prepared site and connect them with pipelines. If you are using a concrete base, especially if the pumping station is located in a residential building, be sure to place and secure rubber pads under the equipment supports. In addition to reducing noise from devices, such gaskets will protect your equipment from excessive wear.

Step 3

We connect the pumping station to the well head and the input circuit of the home water supply. At the connection between the pumping station and the water intake well, it is necessary to provide for the placement of a check valve and a shut-off valve. In addition, a check valve is also installed at the outlet of the pumping station complex (on the inlet water supply pipeline).

Important! Do not forget that “water will find its way everywhere,” so insulate especially carefully the connecting sections of pipelines and equipment components.

Step 4

We are conducting a test run of the equipment. We fill all the equipment with water; to do this, using the filler neck, we run water into the pumping device, the pressure accumulator and into all the lines. Opening everything shut-off valves and start the electric motor of the pumping device.

The pumping station operates as follows:: the impeller of the pumping device pumps water into the system until the pressure parameters set by the automation are reached. Typically, the pressure in the water supply system is 1.5 - 3 atmospheres. The indicator at which the pump stops can be adjusted using an automation unit.

Video - DIY pumping station

For a private home it will save the situation. The distribution of pipes to plumbing fixtures in the house and the raising of water from the depths are combined into one system. This ensures constant pressure in the system. If the pump simply pumps water from a well into a container, then the pumping station is a system in which the operation of the mechanism is controlled by automation, maintaining the flow and pressure in the water supply.

Pumping station equipment and operating principle

The photo shows the equipment and connection diagram of a pumping station for a private house. The kit includes:

pump:
storage tank or pressure tank;
pressure gauge;
pressure switch;
control automation.

The equipment is selected taking into account the maximum disassembly of all cranes and peak load. You need to know that the parameters, pressure and performance of the pump are interdependent. The presence of automation simplifies the maintenance of the water supply system. A pumping station for a private house is installed in a utility room or pit next to it. The circuit wiring is also done there.

Foreign-made pumping stations, depending on performance, cost $400-500.

The included pump is selected not only by power and pole lifting height, but also by design:

A pump with a built-in ejector will lift water from 45 meters. Water is pushed into the battery due to the vacuum in the pipe. The pump operates noisily; it can be installed in a caisson or in a utility room.
The pump with a remote ejector operates silently, since the unit is located on the suction line below. But such a pump can pump clean water, without suspension.
A pump without an ejector is used to lift water from a depth of up to 10 meters. The devices operate silently and are inexpensive.

A water tank complete with a pump can be either a separate storage tank or a hydraulic accumulator. The storage tank is installed at a height to ensure stable pressure in the system. The level is adjusted by a float. Such a storage device is inexpensive, but the risk of flooding the room if the float malfunctions is high.

The hydraulic accumulator has a small volume and is controlled by a pressure sensor. The compact container does not require a special location.

A pumping station for a private house with a hydraulic accumulator is the best solution.

The operation of the station is controlled automatically. After the system starts, the pump turns on, water enters the accumulator and fills the system. When the required pressure in the pipelines is reached, the automation turns off the pump. The pressure in the water supply is maintained by an accumulator tank. The pressure in the tank is adjusted by the manufacturer in the range of 2-3 bar. The pressure in the line is controlled by a pressure gauge. This is the operating principle of the pumping station.

Selecting a pumping station

Manufacturers offer a wide range of equipment. Users do not always choose a station. So, for summer residents with seasonal residence, the pump is more suitable. Create comfortable conditions It is impossible to live in a rural house without a well-thought-out water supply system. How to choose a pumping station for a private home? It is necessary to determine the need for water and the depth of the aquifer, the distance from the well to the pumping station. You will need data from the well passport:

depth of the mine well;
mirror statistical level;
dynamic water level.

Water flow from taps is determined at the rate of 4 l/min from the tap and 12 l/min for the shower. the productivity should not be much higher than the requirement. Greater productivity increases cost and energy consumption. In this case, there is a possibility of draining the well.

Statistics show that a family of 4 people requires a station with a capacity of up to 4 cubic meters. m per hour, with a pressure of 50 m. A 20 liter hydraulic accumulator will cope with the task. Household pumping systems have a power of 0.6 - 1.5 kW.

The installation of a pumping station in a private house must meet the following requirements:

provide a capacity of 2-6 cubic meters. m/hour;
the volume of the storage tank should provide a reserve in case of a power outage;
protection against dry running is provided;
have a convenient control method - automatic, manual or remote.

Manufacturers of pumping stations

All foreign pumping stations should be connected to network electricity only through a voltage stabilizer. Electrical equipment from European manufacturers is designed for power supply of 230 volts and stable parameters.

Users choose equipment from well-known manufacturers. The following installations are considered the best pumping stations for a private home:

Italian Marina stations lift water from a depth of 25 m. They have a cast iron body and a reliable automatic control system. Installation power 1.1 kW, productivity 2.4 cubic meters. m/hour.
Pedrollo stations are produced to suit various requests. Water lifting depth 9 - 30 m, productivity 2.4 - 9.6 cubic meters. m/hour. Batteries included with a capacity of 24-60 liters.
Karcher pumping stations are the most popular and are considered the best for a private home. Steel hydraulic accumulators with a capacity of 18 -40 liters, automatic regulation, capacity 3.8 cubic meters. m/hour – all parameters are designed for a family of 4 people.
The German company Wilo is the oldest manufacturer of pumping equipment. The equipment has a high degree of protection and reliability. The power of the stations is 0.55 - 1.6 kW, it is possible to choose a suitable model in a plastic or steel case.
The Russian company "GILEX" produces pumping stations, but they are inferior in quality to foreign models. Their advantage is the ability to pump muddy water and adaptability to the specific conditions electrical networks. Assembling the station is difficult, spare parts are not always available.

When choosing a pumping station, you need to take into account that a metal body and a metal tank will last longer.

It is imperative to choose a manufacturer that supplies products from the brand’s homeland. Products manufactured in third countries do not have a manufacturer's warranty.

Correct installation of the station

How to install a pumping station in a private house? Further work without vibration and unnecessary noise depends on correct installation.

The installation is delivered to the market ready for connection. All systems are debugged. It remains to determine the installation location and equip it. A monolithic foundation is being created for the station. Communications are brought to the connection point. It is necessary to install a check valve at the pump suction so that the system is flooded. A filter is installed on the pipe to prevent pebbles from entering the impeller. The equipment must be installed using anchor bolts using vibration dampers.

The assembled installation is grounded. The suction pipeline is filled with water through a funnel. After turning on the station, check the tightness of all connections. It is better to install the system with the assistance of an experienced specialist. It is necessary to provide space heating in winter. If the equipment is installed in a pit or caisson, the temperature there will not drop below 0 degrees, but the lid should be insulated from above.

Choosing a pumping station for your home - video

Believe me a private house can be furnished with such a high level of comfort that living in it will be much more convenient than in a city apartment. In any case, the water supply can be used with no less convenience. In the same way, to get water you will only need to open the tap, which is not yet very compatible with suburban infrastructure, do you agree?

But this is not a “rosy” dream at all. To implement the idea, it is enough to include a pumping station in the water supply scheme. She will do a colossal amount of difficult physical work for her owners. True, to properly connect and operate it, you need to know the equipment design well.

We offer you valuable information about the specifics of using this technology. Our article will help you understand the operating principle of the pumping station and introduce you to the installation rules. The information we provide is supplemented with extremely clear diagrams, photo collections and video tutorials.

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 connecting is not too difficult a task; if you wish, 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 a 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 whole point is that maximum depth lifting pumping stations - 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 - a 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. The safest way to install a pumping station is 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 a similar room is made in the basement or on the 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 - the 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 (like a 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 you can also slab polystyrene foam, cut into strips and glue it. For rectangular pits and structures, slabs are suitable that 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 chosen 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 of excavation work: lay the pipeline higher, but insulate it well and use it additionally. This may be the only way out if the groundwater level is high on the site.

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 a pumping station is installed with a centralized water supply. In this case, a water pipe is connected to the station input (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 comes out at the place where the casing ends. 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 tap 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 air - air pockets that formed when filling the pumping station come out. When water flows in a smooth stream without air, your system has entered operating mode and 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:

there is 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.
