Connecting a pumping station to a well with your own hands. Diagram of the correct connection of the pumping station to the well, drawings and tips

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. 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, automatic control system or 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.

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. With its help, adjustments are made.
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 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 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

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. Loud station noise and comfortable stay- the concepts are incompatible, so for installing a pumping station at the dacha it is better to prepare separate room.

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 that is below the freezing level of the soil. 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 - mineral wool on a basalt basis.

Exterior works

From the outside polypropylene pipe We attach a metal mesh that 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 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 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 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.

It is not always possible to use a centralized water supply, especially if the housing is somewhat remote from the city. But sometimes you have to connect special equipment, such as a pumping station for a home, the connection diagram of which depends on the operating conditions and parameters of the water source (well, well), and in conditions of insufficient water pressure from the central pipeline.

The most important, main components are the pump unit itself and the storage tank. Depending on the design, the mechanism is controlled by an automation unit or a float element. The result is that each of the active nodes occurs in different versions. For example, the drive exists in the form of a hydraulic accumulator and a tank. The pumping unit itself may or may not be equipped with an ejector. Moreover, the first of these options can be made with a built-in or external ejector.

Devices with a storage tank have a long list of disadvantages, including the main ones: large dimensions, and therefore difficulties during installation, as well as the lack of forced action on water, which does not contribute to an increase in pressure in the system.

The most common versions today are those with a hydraulic accumulator.. The principle of their operation is based on the features of the main unit, which is divided inside the cavity into two compartments. Both of them are responsible for different functions: pumping air or water.

The pressure level is monitored by a relay, which turns off the device when the pressure reaches a certain level. If the value of this parameter drops to the minimum limit, the relay is activated and the device is put into operation. Despite its popularity, this type of equipment also has its drawbacks, in particular, the tank is not very spacious.

with hydraulic accumulator

Basic criteria for choosing a device

Installation of a pumping station in a private house is preceded by careful selection of the most suitable model. Among all the functions, including the least important ones, you should first of all pay attention to the following:

suction depth of the device, which must correspond to the parameters of the well itself, because if these parameters correspond, as well as with sufficient power, you can get highest level productivity;
water supply speed, also known as productivity;
power of the device, but you should not choose a model with the largest margin for this parameter, as this will lead to unnecessarily high energy consumption;
device control type: manual drive or automation;
the number of people who will use such a water supply system in the future;
tank volume, which will allow you to use the device for a long time without connecting to the mains.

If we talk about the performance of the device itself, then this parameter never should not exceed the natural productivity of the water source(wells, wells). If these characteristics do not match, the liquid will be pumped with impurities.

A do-it-yourself pumping station for a dacha is connected based on some information about the composition of the family. So, if the power of the device is not sufficient to provide the required speed of pumping water, then there will not be enough water in the system to supply a large number of people living in the house, which will lead to a weakening of the pressure and uninterrupted operation of the device.

For example, in order for a family of 4 to be able to use a local water supply system, a device performance level of approximately 3 cubic meters is required. m/h, however, this figure may vary depending on the level of intensity of water use.

The principle of choosing a site for installation

The main disadvantage of pumping stations is the impossibility of using them during the cold season in unheated rooms or in open areas. It happens that users organize additional heating for devices standing on the surface of the earth, protected only by primitive construction. In this case, of course, there will be some effect from such actions, but in reality the result will only be excessive fuel consumption (if an liquid fuel heater is used, for example).

For more efficient and economical use of such units, before connecting a pumping station in a country house or in a private house, it is recommended to adhere to a number of rules:

the location for installing pumping equipment should be chosen taking into account the possibility of installing a centralized heating system, and the presence of energy sources in the room is not desirable;
It is recommended to organize free access to the device, which will simplify maintenance even in the event of equipment failure;
professionals advise install such equipment as close to the water source as possible(well, well).

As you can see, if you plan to purchase such equipment, the connection diagram for a pumping station for a home or cottage from a well or should cover all possible features, up to the organization of a special room for these needs.

Choosing a system: one-pipe or two-pipe?

In total, there are two options for connecting equipment of this kind, each of which requires the need to take into account several parameters: the installation depth of the equipment, the configuration of the water supply. Thus, a distinction is made between one-pipe and two-pipe systems for connecting pumping equipment. In the first case we're talking about about shallow depths, while the second option is usually used to increase the depth of water suction by a pump from a well.

More specifically, some boundaries can be noted for both cases. For a one-pipe system, a threshold of up to 8 m depth is sufficient, for a two-pipe system – from 8 m or more. Moreover, the second option assumes use of pumping equipment with an external ejector.

How to connect to a water source (well, borehole)

Usually the location of the well is in close proximity to the home, which greatly simplifies the extraction of water and its supply to the house for the general needs of the family. Accordingly, you will not have to dig an endless trench to lay a pipeline, which is one of the main links in the chain of organizing local water supply using a pumping unit. Main works:

Preparation of trenches, which are made at a depth below the soil freezing level and with a slight slope towards the water source to increase the efficiency of equipment operation and water supply to the site.
Preparation of a polyethylene pipe with a diameter of 32 mm from a well (well) for connection with pumping equipment. At this stage, a check valve and a mesh are mounted on its end part. Moreover, installing a pumping station in a dacha with your own hands does not necessarily have to imply independent fastening of these elements, since it is quite possible to purchase a ready-made pipe with a check valve connected to it and a coarse filter (also known as a mesh).
The connection to the pump unit is made using a coupling, metal corner threaded.
Next, the pipe leading to the water supply is connected to the pumping equipment according to the principle described above, using a combined coupling with an angle of 90 degrees and an “American” one.
Before the first start, water is first poured into the pump unit through a special hole.

A detailed connection diagram of the pumping station is shown in the photo.

When installing a pumping station at a dacha, an important nuance is at what level the pipeline is located. If the trench has a depth below the soil freezing level, then you can do without special thermal insulation of the pipes, otherwise you should use mineral basalt fiber, polystyrene foam or electrical cable. site. Comfort of operation and reliability of pumping equipment depend on proper configuration of this device.

Organization of connection to the water supply

When connecting a pumping station to a central water supply, connecting elements (fittings) are also used. A connecting element is attached to each of the holes (inlet and outlet), providing a hermetically sealed fastening of the pipeline. The pipeline from the pumping station is connected to the water supply using a special insert or tee.

For better water purification It is recommended to install two filter elements: coarse and deep cleaning . Moreover, there are some nuances when installing such parts. Before connecting to the internal water supply, a deep cleaning filter is installed, and a coarse filter element is mounted at the inlet of the pumping station. After fastening all the elements, the equipment is started.

Thus, in total, not much work needs to be done at the stage of connecting a pumping station for a summer house and home, but it is the preparation that takes more time, for example, digging trenches for laying a pipeline.

For greater convenience, some tricks are often used to smooth out the operation of such equipment, in particular, installing the pump on a concrete or brick base, on top of which a rubber mat is placed. In this case, the equipment is fixed to the base using anchors. This will somewhat smooth out the effect of vibration during operation of the device.

Additional information on how to install a pumping station at your dacha with your own hands is presented in the video.

When installing a well water supply system, the master has to solve a number of rather complex problems. And one of them is to connect the pumping station to the well with your own hands - after all, only when correct installation and setting up this unit, we will receive water without interruptions and in the required volume.

Below we will talk about what such systems are and also describe in detail the process of their installation.

Device layout

To lift water from wells and shallow wells up to 20 meters located in private households, either submersible pumps, or automatic pumping stations. And it is the second option in Lately is becoming more popular, since such a station includes a whole complex of equipment that ensures uninterrupted operation of the entire system.

As a rule, the pump unit is equipped with the following parts:

The pump itself, most often centrifugal type. The device is responsible for lifting water and transporting it through pipelines.

Note! Sometimes such a pump is installed in addition to a submersible pump, especially if there is a need to raise water from a deep well to the upper floors.

A hydraulic storage tank, which is a tank divided by a membrane into several sections. Thanks to this design, the pressure in the system changes more smoothly, and the automation responsible for starting the pump part turns on less often. Also, using a battery softens water hammer, which has a positive effect on the condition of all connections.

Pressure switch that responds to changes in the system. As soon as the pressure level in the pipelines and/or accumulator drops, the relay starts the pump motor and water begins to flow into the pipes from the source.
Pressure gauge for recording changes.

To deliver water from a well or well, a water intake system is used, which is an intake hose equipped with a check valve. A central pipeline is installed at the outlet, which connects the automatic station to the house and all points of consumption.

Choosing a place

Before starting work on installing the pumping unit, you must select a suitable location.

The requirements for it are as follows:

Firstly, the system should be located in close proximity to a water source. This will allow us to ensure the most efficient water intake without loss of power.
Secondly, the device must be protected from exposure to precipitation. Of course, most pumping stations are produced in sealed housings, but permanent job They are clearly not designed for rain and snow.
Third, the installation location must provide access to the system for adjustment and maintenance work.
Also, do not forget that the pump’s electric motor makes quite a lot of noise, so they should not be installed in residential areas.

From this point of view ideal place for installation there will be a basement of the house (if the well is located in close proximity to the foundation), a pit or a caisson. You can also place the control station in the well itself, securing it on a special shelf under the neck.

Laying pipes

After the installation location has been chosen, we need to lay a pipe from the house to the water source.

The instructions for performing the work in this case are quite simple:

We dig a trench with a slope towards the well. The depth of the trench should be slightly greater than the depth of soil freezing - this will protect the pipe from the formation of ice plugs.
We fill the bottom of the trench with a sand cushion up to 20 cm thick.
We lay the pipe, having previously wrapped it with heat-insulating materials.

Note! As an alternative to insulation, you can use a self-regulating heating cable.

We make a hole in the foundation through which we insert the pipe into the basement or subfloor.
We connect the pipeline to internal wiring, carefully thermally insulating all areas in unheated rooms.
We connect the other end of the pipe to the pumping station through a special fitting with a check valve and a mesh to remove suspended particles. The price of such a part is low, but its use significantly increases the stability of the system.

Connecting the unit

The connection diagram for a pumping station for a well is quite simple, and it can be implemented with even minimal skills:

First, we prepare the base on which the station itself will be mounted. Best suited for this small podium, made of brick or cast from a monolithic reinforced concrete. Minimum height such a podium is about 20 cm.
A rubber mat about 10 mm thick should be placed directly under the legs of the unit. The elastic material will effectively compensate for vibrations, reducing equipment wear and noise levels.
We install the pump feet on a rubber gasket and fix them using anchor bolts with wide washers.

To connect we use:

Inch coupling with external thread.
Steel or bronze corner with external thread.
A check valve of suitable diameter ensures uniform flow of water into the system.
American connection.

We connect all the details into unified system, connecting the water intake pipe to the pumping part. In this case, it is necessary to ensure the tightness of all joints.

Using the same method, we connect the outlet pipe. As noted earlier, a coarse metal mesh filter can be installed here.

Our system can be optimized by installing a pre-filter in front of the pump part. The use of this inexpensive device allows you to extend the life of the pump, since particles of clay and sand entering the flow section are the main factor in wear of parts.

Note! Centrifugal models suffer from poor quality water somewhat less than vibration ones, however, even for them, installing a filter can be considered very desirable.

Absence central water supply is no longer an insurmountable barrier to providing water to private houses and summer cottages in the countryside. This issue is easily solved by installing wells or boreholes of varying depths on the plot of land, depending on the location of the aquifer. To create a pressure in the water supply network sufficient for the connection and constant operation of plumbing equipment, pumping stations for wells are used.

These compact units ensure the lifting of water from a depth of up to 20 meters and its uniform distribution under good pressure to all water consumption points in the house. Thus, a person does not experience any discomfort due to lack of water or its absence, unless there are interruptions in the supply of electricity. However, this problem can now be solved through the use of generators and mini-power plants.

Selecting the appropriate pumping station model

Operating principle of one-pipe and two-pipe stations

Depending on the type of suction pipeline device, all pumping stations can be divided into two groups:

single-pipe;
two-pipe (ejector).

For single-pipe stations, the water intake design is very simple, since water flows through one line into the pump housing. For two-pipe stations, the design structure is much more complex. But this equipment, having less power, is capable of lifting water from greater depths. This is achieved due to the fact that the water rises due to the vacuum created by the pump impeller, which increases due to the inertia of the water, which circulates in a circle during operation of the station.

Choosing a location for a pumping station

If possible, it is better to connect the pumping station to the well not in the basement of the house, but in a separate building on an area located away from the house. This will relieve people living on site from the noise that occurs when the equipment is operating. The room must be dry, since only in this case is the proper and safe operation of pumping equipment that depends on electricity possible.

In the technical room, the station is installed on a solid concrete floor or on a pedestal made of bricks or wooden blocks. Before installing the unit, it is advisable to place a rubber mat under it, which will partially absorb vibrations. The pumping station is attached to the base using anchors, which are driven into the holes provided in the legs of the unit.

It is better to install a pumping station that makes noise during operation in a separate room, located on a plot of land near the well.

If the water supply to your home is not from a well, but from a well, then the following material about connecting equipment may be useful to you:.

Self-installation and connection

The two outputs available at the pumping station are designed to connect it to the well and to plumbing system Houses. First, start connecting the unit to the well. To do this, take a polyethylene pipe, the diameter of which should be 32 mm. The pipe, of course, must be solid, which will eliminate the possibility of leaks. Therefore, it is better to buy a pipe with a small margin; if necessary, the excess can be cut off. One end of the pipe is lowered into the well, and the second is connected to a pump built directly into the station. If necessary, the polyethylene pipe is insulated using materials produced by Termoflex as insulation.

A metal mesh is attached to the end of the pipe, lowered into the well, which serves as a coarse filter. A check valve is also installed there, which is necessary to ensure that the pipe is constantly filled with water. Only in this case will the pump be able to pump water from the well. To secure check valve and the filter use a coupling with an external thread.

The second end of the polyethylene pipe is attached to the pump using the same coupling. First, an American tap is connected to the outlet of the station, then a coupling with an external thread is connected to it, and then a polyethylene pipe using

The pumping station is connected to the pipeline using the second outlet, which is usually located in the upper part of the unit. At the same time, an American tap is also connected to the station threaded connection. Then a polypropylene combined coupling is screwed into the tap, the diameter of which is 32 mm, and the angle is 90 degrees, the length external thread- 1 inch. Durable polypropylene connection water pipe with the coupling is ensured by soldering these elements.

You may find this material with instructions for troubleshooting the most common problems useful:.

As you can see, you can carry out the work of installing and connecting the pumping station to the well yourself. If you do not want to delve into the intricacies of conducting installation work, then hire specialists.

A pumping station is necessary to provide cold water supply in the absence of a central network or interruptions in its operation. The source of water can be a well or an equipped borehole. In the first case, a stationary or temporary technique can be used. The connection diagram of a pumping station to a well or well depends on several factors.

The optimal location of the pumping station depends on its parameters. The maximum suction depth, lift height, pressure value and rated power are taken into account. They are selected according to the characteristics of the well. These include its distance from the house, the minimum water level relative to the ground horizon.

Additional factors influencing the drawing up of a diagram for connecting a pumping station to a well:

Temperature environment. Affects the method of laying the pipeline - underground or on the surface.
Labor-intensive maintenance. If the station is located outside the house, repair and maintenance work can be carried out without difficulty.
Electrical network parameters - maximum load power and the ability to connect power to the pumping station.

The optimal scheme is drawn up based on the manufacturer's recommendations. IN technical passport the maximum and minimum temperature effects, the permitted degree of ambient humidity and the characteristics of the electrical network are indicated.

Well connection diagram

General concept for developing an organization method autonomous water supply includes a pumping station connected by a pipeline to a well and mains in the house. An important point is a choice Supplies and components. It is best to carry out work in the summer.

Design stages:

Selecting a station location.
Drawing up a pipeline laying diagram.
Supply line complete set.
System protection measures.

Details depend on how the pumping station is connected. For each specific case, the optimal components are selected.

Mobile option

It is relevant for seasonal organization of water supply in the country. The advantage is the possibility of using a low-power pumping station. Its location is as close as possible to the well. The installation is mounted on a flat surface, protected from rain by an awning.

In this case, pipelines are installed with a coupling threaded connection - a collet coupling. Manufacturing material – cross-linked polyethylene. They have sufficient flexibility; with the help of couplings you can create a branched watering system personal plots and water supply to the dacha.

Components of the scheme for temporarily connecting a pumping station to a well:

supply line - strainer for coarse cleaning and check valve;
distribution pipeline - tap to shut off the water supply, fine filter;
safety devices - pressure switch connected to the comb, pressure gauge.

When drawing up the diagram, you need to minimize the number of turns of the pipeline. Maximum slope distribution line should not exceed the permissible limit.

Fixed connection

For this option, water supply organizations set up a separate room. Most often this is a basement or basement room. It must be insulated, since the impact negative temperatures into the station or water in the pipeline can lead to system failure. Additionally provided.

The list of connection diagram components is the same as described above, with the addition of the following elements:

the distribution main has a drain pipe to remove water from the pipes in the house;
it is recommended to install storage tank, located at the highest point of the system;
if there is a possibility of a power outage, the pumping station is connected to a UPS or an autonomous electricity generator.

In addition to correct installation, it is necessary to timely check the operation of the system. Work is being done to clean the pipes and check the integrity of the membrane expansion tank, the condition of the pump is monitored. The water level in the well should not be lower than the end of the supply pipe.
