Correct installation of the pumping station. Installation of a water pumping station in a private house. How to connect the station to the water supply

It is impossible to imagine the home of a modern person without the usual benefits of civilization. Water in the bathroom, water in the kitchen - for cooking and washing dishes, water for cleaning and washing, for watering the lawn - we are used to getting all this by opening the tap.

And if apartments have this opportunity, thanks to a centralized water supply system, then residents of private cottages need to buy a pumping station, install and connect it - that is, create their own water supply system themselves.

Naturally, owners of private houses have a logical question: how to properly install a pumping station? We will answer it and figure out how to connect the pumping station, even if you have no experience in such matters.

Where to place it?

Methods of water supply can be either permanent (when the installation is used to perform a certain job for a long time, for example, it provides water to a residential building), or installed temporarily - devices used in dachas, for irrigation, for draining a swimming pool (for example) .

Initially, you should decide where it is better to install the pumping station:

In a specially equipped room (ideally) - this is important if the device will operate all year round. The room must maintain a positive temperature.
In a caisson (protected well).
In a well (of course, if it is a well pump).
On the surface, above the water source (well, pool, tank) - if the pump is surface, and inside the source - if it is submersible.

The nuances of choosing a location for a pumping station:

Pumping equipment is installed and secured on a solid, reliable foundation— it must be level, stable, non-slippery, able to withstand the weight of the station (if it is a suspended support and the station is heavy), and must be located away from aggressive chemical compounds and fire-explosive materials.
The room in which the device will be located must allow easy access to the station- for control, maintenance and repair - if necessary. As mentioned above, the room must maintain a positive temperature.
The room where the station is installed must be soundproofed— the operation of these devices is accompanied by noise and vibration. Of course, there are also less noisy models, but if you have chosen a powerful device and plan to place it in a residential building, it is better to pay attention to this point.
Low indoor humidity levels are another requirement.

Connection nuances

Connection options for the pumping station depend on the water supply system. The methods for installing a pumping station are as follows:

Single-pipe - the usual and most common method.
Double-pipe - used to increase the depth from which it is necessary to raise water.

The model of the pumping station directly depends on the depth of the water. If the water supply source lies at a depth of no more than 10 m, then it is best to use a single-pipe connection method.

And if it is more than 10 meters, then a two-pipe option, and two-pipe type pumping equipment must be installed with an ejector.

Before starting work, it is advisable to draw a plan of what the installation diagram of the pumping station will look like - to make it easier for you to understand the connection sequence. In fact, there is nothing complicated about it, and all the work does not require any specific skills.

The pumping station installation diagram reflects all the constituent elements of the base pumping station down to the smallest detail:

Storage tank;
Pump;
Pressure switch;
Check valve;
Filter.

Correct installation ensures stable operation of the pump and the entire system as a whole. You should remember the following nuances:

Installation of a pumping station in a caisson has its own characteristics. It must be installed much lower than the freezing level of the ground cover - from 1.2 to 1.6 meters (depending on the region).
The structure where the water supply station is installed must be heated.
When connecting the pumping station with your own hands, remember that each connection must be as tight as possible. This applies to connecting hoses to the pump - this requires either the use of seals or the use of clamps.
The use of reliable filters is strongly recommended - this part will protect the devices from the entry of solid particles. It goes without saying that sand and any small debris (silt, crumbling stones from the walls, etc.) will not benefit the pump - over time, this can cause a problem. So a filter must be present, and it should be cleaned periodically and, if necessary, changed.

Step-by-step installation instructions

The connection diagram for water supply pumping stations has been drawn up, the equipment has been purchased, now it’s time to become familiar with exactly how to install a pumping station with your own hands.

First, you need to carefully familiarize yourself with what the electrical diagram for connecting the pumping station looks like. The electrical connection is made via a cable through a circuit breaker - everything is simple and clear: one cable running from the pump to the outlet.

The design of pumping stations is conventionally divided into two groups: these are surface ones - pumping water through a hose lowered into the water, and standing on the surface; and submersible - when the pump itself is lowered into the water.

Installing a pumping station with your own hands looks like this (meaning a surface-type device):

A system plan is drawn up: the place where the installation will be located is selected, how the lines will approach it and where they will got leave.
The station is installed at the selected location.
A hose is connected to the suction pipe, the other end of which is lowered into the water to a depth of at least 20 cm.
The station is filled with water through the discharge pipe.
A hose is placed on the discharge pipe through which water will flow into the system (it does not matter where exactly - for irrigation or into the house).
The device connects to the network.
The device starts working.

As you can see, installing a pumping station in a country house or cottage is not too difficult.

Before installing a pumping station in a well, it is necessary to install a check valve on the supply pipe. It ensures a continuous supply of water to the house and prevents it from backflowing from the system.

The submersible device is installed in essentially the same way, only starting from point 5. The pump itself is lowered into the well using a tied cable. In this case, it is recommended to tie the cable, hose and power cable in several places with electrical tape.

It is also possible to connect the pumping station to the water supply - in case you want to power another line from it (for example, for irrigation). In fact, everything is done according to the scheme described above, with the only difference that the hose will not be lowered into the well, but will be connected to the water supply.

The same is true when you need to connect the pumping station to the tank - the hose is lowered (or connected) into the desired container, and the further steps look exactly the same.

Installing a pumping station in a well has its own nuances. This task is already many times more difficult, and it will not be so easy for an inexperienced person to cope with it without the help of specialists.

By the way, connecting a hydraulic accumulator to a pumping station is a responsible task. After all, it is this container that will provide your home with water if the power supply suddenly goes out, or if the pump breaks down.

During installation, a submersible pump is attached to a cable in the thickness of the water column, closer to the bottom. A protective mesh (the same filter) is installed, which prevents the entry of solid particles.

Connecting the pumping station to the well is carried out as follows:

A reliable cable is attached to the pump - it will be used to both immerse and lift the pump from the well. If it breaks, the device will have to be pulled either by the power cable or by the hose through which water flows. It is not a fact that they will withstand - the weight of the devices is considerable, so there is a high risk of getting into a difficult situation when the pump remains lying at the bottom of the well, at a depth of several tens of meters.
A hose is connected to the pump through which water will flow. The hose, cable and power cable are tied with electrical tape in increments of 50-100 cm.
The device is immersed in the well.
The well is pumped until clean water comes out of it. At first (from several to several tens of hours) muddy and dirty water will come out of it, naturally unsuitable for drinking or for domestic needs.

We figured out how to properly connect the pumping station. Now let’s pay attention to the financial side of the issue and give a couple of figures - if you want the installation of the pumping station to be carried out by specialists.

The price of installing a pumping station depends on the amount of work and complexity of equipment installation. The price of installing a pumping station with a connection to the water supply system of a residential building varies from 2,500 to 3,000 rubles.

The cost of installing a pumping station in a well will already be more expensive - here you can hardly expect it to be cheaper than 5,000-8,000 rubles.

Pump installation (video)

A pumping station for a private home is a factory-assembled apparatus (device) designed to lift and deliver water from a source to the house, as well as automatically control this process.

The lifting and delivery of water is carried out by a pump (borehole or surface), maintains the water pressure in the system by a hydraulic accumulator, and controls the on/off of the pump, an automation unit connected to the hydraulic accumulator.

At the end of the article I will give a diagram for connecting the pumping station to the water supply system at home, but in this article, it is more important that for the ANSV (automatic water supply pumping station) to work, it must be correctly and safely connected to the power supply.

Correctly connect the pumping station of a private house to the power supply

When connecting a pumping station to the water supply system at home, connecting the station to the power supply is often relegated to the background as an insignificant connection, comparing it with connecting, say, a vacuum cleaner.

There are all external factors for this. The pumping station kit includes a power cord connected to the connection block and equipped with an electrical plug. Everything seems to be ready, plug it in and start working. However, it is not. Due to the fact that the ANSV is simultaneously connected to electricity and water, its power supply line requires special rules for safe installation and it is necessary to protect people from possible electric shock.

Pumping station power supply line

ANSV operate when connected to an uninterrupted, stable power supply of 220±5 V. Voltage surges in the network can lead to failure of the station.

I will formulate a few general rules for a safe power supply line for a pumping station at home:

1. To power the pumping station, you need to select a separate electrical circuit (pumping station group);

2. The group for the pumping station must be protected:

Pair: circuit breaker + (30 mA);
One: (30 mA).

3. The pumping station group must be grounded. The grounding wire must be connected: in the socket to the grounding terminal, in the switchboard: to (GZSh).

It is strictly prohibited to ground (ground) the pumping station by connecting the neutral wire to the ground terminal in the socket.

Type of socket used to connect the pumping station at home

According to your passport, you need to connect the pumping station of a private house to an outlet. The cord and plug are included and are already connected to the station (worth checking).

The electrical outlet for connecting the pumping station must have a grounding contact.

Depending on the installation location of the pumping station, the degree of protection of the outlet is selected. Particular attention is paid to protecting the outlet when installing the pumping station in a caisson, next to the source (well, well). In this option, you need to use a sealed socket with IP=65.

connect the pumping station of a private house in a caisson

Laying the power supply to the pumping station along the street

If the pumping station is installed outside the house (near the source in an equipped caisson), the power supply line will have to be laid along the area from the house to the caisson. In this case, the power supply line must be laid according to the rules of street (external) electrical wiring in a trench.

The depth of a separate trench, different from the trench for the water supply, should be 80 cm deep, in the shape of a trapezoid, with a sand cushion at the bottom.
The electrical cable in the trench must be protected with a plastic pipe, including the descent/ascent of the cable from the trench into the caisson and the house.
The pipe can be replaced with electrical corrugation.
The passage of the cable between the foundation of the house and the caisson wall must be made in a sleeve.

Theoretically, and this will not be a violation, the cable can be laid in the ground without protection. Not recommended.

Having filled the cable 15-20 cm to mark the route, lay the signal tape along the route.
For backfilling, use soil free of debris.
Route connections of the power supply cable should be avoided.

Note: If you have experience, you can remove the electrical plug and connect the power cable directly to the connection block located on the pump. Not to be confused with the pressure switch on the side of the station.

Selecting the cross-section of the power supply cable for the pumping station

Each pumping station has a power consumption specified in the passport. The cross-section of the power supply cable of the pumping station is selected according to its power, based on the general rules for choosing the cross-section of electrical wiring. read or count like this: 1 kW of power = 1 square wire cross-section.

You are unlikely to find an ANSV for sale on sale for a home with more power than 1600 W. Theoretically, an electric cable, naturally copper, with a core cross-section of 1.5 mm 2, is suitable for powering the station. In practice, it is better to use a 3x2.5 mm electrical cable. Cable brand VVG.

Turning on the pumping station

It is important to understand that no protection devices will save the station from malfunctions if you try to start it “dry”. Before starting the station, fill the system with water through a special valve.

The automatic switch of the pumping station turns on after the system is filled with water.

After selecting and purchasing pumping equipment, the next step is its installation, connection and configuration. The water pump pumps water directly into the house - to the water supply pipes or to the water heater in the cottage heating system.

In many cottages or dachas there is not only central heating, but also water supply. To do this, the owners of the site equip a well or borehole to have access to water. To supply water to the house, a submersible pump is most often used, which pumps water when the tap in the house is opened. The disadvantage of this equipment is the inability to use water when the water level in the well is low or there is a power outage.

A pumping station will allow you to avoid many inconveniences, since it consists not only of a water pump, but also a storage tank for water. The criteria for choosing a pumping station are collected in our article:

When faced with the problem of pumping water directly from the well, the hydraulic pump turns on and supplies water to the house from the tank. When the station operates, a surface pump is used, which allows you to pump water even from a small well. This is very convenient for small areas where it is not possible to dig a large well and equip it with a submersible pump. Water enters the water supply system through a special device - a hydrophore, which maintains a certain level of pressure in the pipes.

Pumping station provides:

residents with drinking water;
coolant heating system;
satisfies the needs of residents (bathroom, shower);

The pumping station supplies water to the house under stable pressure through the water supply system - thanks to this, there is water not only on the lower floor, but also on the upper floor.

What kind of pipe is needed for a pumping station: equipment models

When purchasing pumping equipment for a private home, you need to take into account all the characteristics, including the type of pipeline. They can be divided into single-pipe (the simplest) and two-pipe (ejector).

If the well depth is no more than 10 m, you can use a single-pipe model of a pumping station; for a deeper well, it is preferable to install an ejector station.

The difference between them is fundamental. The single-pipe pumping station is easy to install and pumps water into the housing along one line. The two-pipe system involves the installation of a cast iron ejector, which must be placed in the water to raise the liquid into the system.

Setting up a pumping station: major equipment breakdowns

Before disassembling the entire pump structure and finding out the cause of the problems, you first need to clean the filters, check the pipes for leaks and eliminate leaks if they occur.

Possible problems:

Clogged device due to lack of filters;
Due to frequent operation, the pump becomes unusable;
Failure of tightness at pipe joints leads to the problem of the pump being unable to pump water;
Reduced air pressure in the system;
The pump turns itself on and off due to incorrect adjustment of the pressure switch;
Friction in the pump can cause increased electricity consumption.

Low water pressure is due to low water pressure in the water supply or air entering the water supply system. To do this, you need to check the operation of the relay and all pipes for leaks. After checking, cleaning and troubleshooting, you may have to re-configure the entire automation.

Correct installation followed by strict adherence to the operating rules of the equipment is the key to long-term use of a pumping station in a private home.

Installation of a pumping station in a private house step by step

The installation of a pumping station may differ depending on the source from which the water will be supplied (well, borehole, centralized water pipeline). To install and configure equipment, a diagram and instructions must be used to avoid problems.

Before installing the station (crazy) with your own hands, you should choose a place for it. If it is a caisson, then its depth must be at least 2 m. Also, the pit has a number of disadvantages - equipment can be stolen, the caisson must be insulated and protected from various weather conditions, and it is inconvenient during maintenance. When installing pumping equipment in the basement, it is desirable that it be heated and absorb noise from the pump.

Depending on the quality of the water, the pump must be equipped with special filters that will purify the water before it enters the pumping station. The principle of pumping water from a well and a well is practically the same. There should be a strainer at the very end. The end of the pump pipe should not reach the bottom, the minimum distance is 1 m.

You can install the equipment yourself:

Connect the unit to the well. Lower one end of a pipe with a diameter of 3.2 cm into the well, having previously wrapped it with a metal mesh, which will act as a filter. Using a special coupling, secure the check valve.
Connect the other end of the hoses to the pump using an American tap and a polyethylene tube.
Connect the station to the pipeline. Twist the water pipe with an American one and connect it to the pump itself.
When the station is installed, you will need piping - connecting all system components to the pipeline.
After installing and connecting all the twists, approximately 2 liters of water should be poured into the pump; for this there is a special hole with a plug, and start the system.

After turning on the unit, it is worth adjusting the pump pressure level. 2.5-3 bar is considered optimal to turn off the device and 1.5-1.8 to turn it on.

When choosing a pumping station, many experts and ordinary users note that installations from Gilex, Marina and Gardena are of good quality. The quality and reliability of pumping equipment has no worthy competitors.

How to start a pumping station (video)

Equipment for pumping water from a well can be purchased at the store, but some specialists can assemble it from separately purchased elements. Self-assembly and installation of a pumping station in a suburban area will significantly save money, and high-quality care of the unit will extend its service life.

Examples of installation of a pumping station (diagram and photo)

You can connect the pumping station to a water supply source yourself. But, at the same time, connecting the station to the water supply must be done in compliance with all technical nuances. First of all, you need to correctly draw up an installation diagram for water supply equipment, and then correctly connect it to the water supply system.

Device and principle of operation

Most wells serving summer cottages and residential country houses have a water supply depth of no more than 20 m. This depth is ideal for using automatic pumping stations.

This device represents a set of equipment designed to fulfill two main purposes:

Supplying water from a water supply source to the intra-house network.
Maintaining the pressure in the plumbing system necessary for the uninterrupted functioning of plumbing fixtures and household appliances.

If there is no water in the house, the functioning of such amenities of civilization as showers, washing machines, kitchen faucets, and sewerage systems is impossible. Therefore, a pumping station for a private house acts as the basis for its improvement.

On the modern domestic market you can find a significant number of different automatic water supply devices designed for installation in a private home. But, despite some design differences, all these models have the same principle of operation and a similar design.

Main functional units of water pumping stations:

Suction pump for lifting water from a well and supplying it under a certain pressure into the internal pipeline system. Most often, a surface pump is used here. But, if you need to pump water from a deep artesian well, deep submersible pumps are used as part of the stations.
or hydraulic accumulator. This device is intended to create a certain water reserve just in case of emergency. For example, if a pump breaks down or there is a power outage, the hydraulic accumulator will be able to maintain pressure for some time, allowing residents to use basic plumbing fixtures.
Pressure sensors (pressure gauges), connected to the relay, and those, in turn, to the pump motor. If the motor overheats, or there is an emergency disappearance of water in the supply system, the control equipment must independently stop the pump to avoid its breakdown.
Pumping station control unit. Here are the on/off buttons, as well as devices for adjusting the operation of the station. With their help, you can set the highest and lowest pressure values at which the device will automatically turn on or off.
Check valve. It is installed on the water intake pipeline and prevents water from rolling back into the supply well.

Basic installation and connection diagrams

When assembling a water supply system, various connection schemes for pumping stations in a private house can be used.

The most common schemes are:

Diagram of direct connection of the device to the supply pipeline.
Scheme with a storage tank.

Direct connection involves placing the station between the water intake and the in-house pipeline. Water is directly sucked from the well and supplied to the consumer. With this installation scheme, the equipment is located in a heated room - in the basement or basement. This is due to the fear of low temperatures. Freezing of water inside the device can cause its failure.

However, in regions with relatively mild winters, it is possible to place a water pumping station directly at the top of the well. To do this, a well buried in the ground is built above it, which is insulated to prevent the water inside the pipeline from freezing. If necessary, it is possible to use an electric heating wire. We will discuss all aspects of choosing an installation location in more detail below.

The connection diagram for a station with a storage tank looks slightly different. Water from the source is not supplied directly to the in-house system, but to a special volumetric storage tank. The pumping station itself is located between the storage tank and the internal pipeline. Water is pumped to the water collection points by the station pump from the storage tank.

Thus, in this scheme two pumps are used:

A deep-well pump pumping water into the storage tank.
A pumping station that supplies water from a storage tank to the water supply system.

The advantage of the scheme with a storage tank is the presence of a sufficiently large amount of water in it. The volume of the tank can be several hundred liters, and even cubic meters, and the average volume of the station’s damper tank is 20-50 liters. Also, a similar version of the water supply system is suitable for artesian wells, when one way or another it is necessary to use a deep pump.

Pump installation technology

Installation of the pumping station is carried out in several stages. The efficiency and durability of its operation depends on the correct installation of the device, so you should approach the matter as responsibly as possible. Before starting installation work, you should choose the most suitable scheme for connecting the pumping station to the water supply system, and also decide on the location of its installation. Only after this is the water supply device connected with pipes and connected to the internal and external water supply systems.

Choosing a location

The location of the pumping station depends on several factors. First of all, this is the supply scheme - direct or through a storage tank. The location of the installation is also affected by climatic conditions. In southern regions, where severe frosts do not occur, the station can be placed directly above the water supply source, or in close proximity to it.

To do this, a chamber buried in the ground - a caisson - is installed above the well. The water supply equipment is placed in this insulated pit, with pipes and power supplied to it.

When water for the in-house system is taken from a well, the station can be placed directly in it. To do this, a shelf is installed on the inner wall of the well, and a pumping station is mounted on it.

It is also possible to install a water supply device in a special booth next to the water source. The only condition is that the station must be located in a room with a positive temperature to avoid freezing of water inside the pipes and damper.

If a residential building is located in the northern region, then it will be difficult to ensure reliable thermal insulation when the station is located externally. The best solution in this case is to place the station inside the house. Usually a basement or basement is used for this.

For an installation scheme that includes a storage tank, placing the pumping equipment inside a heated room is the only possible option. The storage tank filled with water must be kept warm in winter. Accordingly, the water pumping station is located next to it.

Carrying out preparatory work

After selecting the station installation point, we begin preparatory work. First of all, the base on which it will stand is installed. You can pour a small concrete area, lay the floor with bricks, or install the device on special brackets. For noise insulation purposes, it is recommended to attach a rubber gasket between the base and the station itself. It will absorb vibrations coming from the operation of the pump and fan impeller.

Next we lay the pipelines:

Internal, going from the pumping station to the plumbing water supply equipment.
External, connecting the station or fill tank to the water source.

External pipes should be laid in trenches located below the soil freezing level. This indicator varies for different regions. For central Russia it is about 0.8-1.2 m, and for Siberia it can be 2.5-3 or more meters.

The trench is dug in such a way that the pipeline has a slight slope towards the well. This is necessary so that during emergency repairs of the pipeline, the water flows down by gravity.

Assembling the water intake unit

The type of water intake unit depends on the type of pump used. If this is a standard surface pump, then the water intake unit consists of a pipe lowered into the well. A check valve and a filter mesh are attached to its end, trapping large debris. At stations equipped with an ejector pump, the water intake unit will have a more complex appearance.

A valve and a filter mesh are also put on the suction pipe, but another pipe coming from the ejector is connected to it. This pipe directs part of the flow from the pump back to the base of the suction pipe. This creates additional suction power, allowing you to significantly increase the height of water supply.

When you need to supply water from a very deep artesian well, you have to use a submersible pump. Its supply depth is up to 200-300 meters. A coarse filter is included with this pump and is installed inside it.

The submersible pump is suspended from the well head on a durable stainless steel cable. The water intake unit should be placed so that it is in the middle of the water column, but no closer than half a meter to the bottom for a submersible pump, and 1 m for a surface pump.

Installation of station surface elements

The station assembly diagram depends on the specific modification of the device. Here one immutable rule must be observed: each of the units is connected to each other through shut-off valves with American threads and valves. This makes it possible to replace failed units without dismantling neighboring ones and without discharging water from the water supply system.

An additional coarse filter is installed in front of the station, trapping sand that has seeped through the filter mesh. Fine filters are installed on the pipeline leaving the station and leading into the building, removing microelements dissolved in it from the water.

If the size of the damper tank included in the station is too small, you can insert a hydraulic accumulator into the water supply system. This will increase the emergency supply in the water supply with direct supply, without a storage tank.

Next, using the manufacturer's instructions, connect the inlet and outlet pipelines to the corresponding pump openings. Pressure sensors with pressure gauges and a control unit are installed behind the hydraulic accumulator.

First launch of the station

The power of the pump electric motor is about 0.7 - 1.5 kW, so it is recommended to connect a separate electrical wiring line to it with an automatic current cut-off device that is triggered in the event of a short circuit. The equipment should also be connected to a grounding circuit.

The launch setting should be set based on the volume of the accumulator:

For a tank with a capacity of up to 30 liters, the set pressure should be 1.5 bar.
For 30-50l – 1.8 bar.
From 50 to 100l – just below 2 bar.

Then you should unscrew the plug from the hole at the top of the pump and fill it with water. Water should be poured until it begins to flow out of the hole.

After this, the plug is screwed back in and the following sequence of actions is performed:

Connect the pump to the power supply.
Open the fill valve slightly to bleed air out of the system.
After the pump starts operating, water should come out of the system outlet after a couple of minutes.

Water supply stations are equipped with several types of pumping equipment:

Standard surface mounted models. Allows you to supply water from a depth of up to 8-9m.
Surface, with internal ejector. The internal ejector system allows you to increase the pressure in the system and the suction depth to 10-12m.
With external ejector. The ejector is lowered to the base of the suction pipe, which increases the water suction depth to 30m. The disadvantage of ejector models is their noise. Therefore, when purchasing such devices, prepare in advance for some discomfort, or take care of soundproofing the room.
Submersible pumps. The use of submersible types of pumping equipment is advisable for wells with a depth of over 30 m. Such pumps are lowered directly into the well, suspended on cables half a meter from its bottom.

Design and principle of operation of the hydraulic accumulator

Hydraulic accumulators are metal tanks, usually with a volume of 20 to 100 liters. They have an inlet and an outlet. These devices are designed to maintain operating pressure in the water supply network when the pump is turned off.

To do this, there is a rubber membrane inside the metal tank, which stretches when the container is filled with water. When the pump turns off, the membrane, due to the compression force, pushes the water contained in the tank into the network. Thus, the pressure necessary for the operation of plumbing fixtures is maintained in the plumbing system.

Basic operating rules

After putting the station into operation, it is necessary to carry out regular preventive inspections. If necessary, wash the filters and tighten the threaded joints. If the filters become clogged, water begins to flow into the network in pulsating jerks, and sometimes stops flowing altogether. The frequency of filter washing depends on the quality of the water in the well.

The hydraulic accumulator should also be inspected approximately once a month. If the pressure reading in its air chamber is below the required level, then it should be raised using a car pump through the nipple. For proper operation and maintenance of the device, you need to carefully read the diagram of the pumping station and the manufacturer’s recommendations, usually indicated in the technical instructions.

Useful video on the topic

Installing a pumping station is quite within the capabilities of an ordinary home craftsman. To do this, you only need the ability to hold the simplest plumbing tools in your hands - a wrench, a screwdriver, and pliers. Naturally, some plumbing experience and ingenuity will not be superfluous. You can clearly see the installation procedure of the pumping station in the video below.

Of all the communications that are installed in a private household, the water supply system is the very first to be created. Moreover, for a long time it has been something more than a banal pipeline ending with a water tap. Modern technologies make it possible to create an effective water pipeline that meets all the needs of the residents of the house, regardless of what is chosen as the source of water supply. That is why the current topic is how to set up a pumping station with your own hands, which is an essential element of a well-thought-out functional plumbing system.

Which station do you need?

Depending on operational tasks

Today, consumers are offered two types of pumping stations - domestic and industrial. We will leave the second type to the professionals; we are more interested in installing a pumping station for domestic use.

The tasks that a household pumping station must solve: providing drinking water, watering the garden, hot water supply in the house, satisfying household needs (bathroom, toilet, washing machine, dishwasher), providing water for the heating system.

You need to clearly understand what tasks the pumping station should solve, further choice will depend on this

Depending on the water source

Connecting a pumping station depends on what source of water supply is planned to be installed or is already available in the individual yard. In principle, choosing this equipment based on this criterion is not difficult, since water can be supplied to the house from three sources: a well, a well or a centralized water pipeline.

Depending on the optimal operating mode

The station can operate in manual or automatic mode. If necessary, you can choose a mobile model. In addition, you need to understand how much pumped water per hour is needed in a particular case. That is why, before going to a specialized store, it is worth making simple calculations.

Thus, it is believed that one person uses 250 liters of water per day to satisfy all his needs in a private home. Installation of a pumping station at the dacha can be carried out taking into account lower indicators.

Where to install the station - in a caisson or basement?

The station can be installed in one of two places - in a caisson or in a special room in the house. However, the most practical option is still considered to be installing the equipment indoors, for example, in the basement. In this case, the installation must be arranged in such a way as to protect the station from damage due to a possible rise in groundwater. That is, the pumping station must be installed on a stand or shelf, and care must be taken that there is no contact with the walls, which will avoid their vibration when the equipment is operating. The basement must be heated.

If the decision is made in favor of the caisson, then it must be insulated, and the station itself must be installed below the ground freezing level. That is, the depth of the caisson will be at least 2 m.

The basement must be heated, and the station in it, as a rule, is arranged on a stand

Two-pipe option for connecting equipment to a well or well

If the depth of the well (well) does not exceed 10 m, then a single-pipe station model will be relevant. At a depth of 10 to 20 m, preference should be given to a two-pipe station with an ejector. Naturally, before proceeding with installation, a pumping station installation diagram must be developed, which will be implemented in practice.

The procedure for performing connection work

Option #1 - connection to a well or well

The algorithm is usually the same:

The ejector is assembled - a cast iron unit with three outlets for connections.
A mesh filter is installed in the lower sector of the ejector.
The rod of the required length (diameter 32 mm) is placed on a plastic socket in the upper part of the ejector.
The required diameter is assembled. As a rule, it consists of two parts equipped with transition connections.
At the outlet of the flow, a coupling (bronze) is installed, through which a transition to a polyethylene pipe is made.
You can ensure the tightness of threaded connections by using flax or sealing paste.
Trenches are dug to a depth below the soil freezing threshold.
The water pipeline is laid in the trenches - the length of the pipes must be generous.
The casing pipe must be equipped with a specially purchased head. However, in practice, such parts are not easy to find on sale, therefore, as an option, an elbow with a smooth angle can be used.
Couplings are used to connect the pipe to the ejector.
Before lowering the second end of the pipe, it is inserted into the elbow at an angle of 90°. To seal the space, it is filled with polyurethane foam. The pipe is then connected to angle adapters (90°), which in turn are connected to the outside of the pipeline.
The ejector assembly is lowered into the well to the required depth, which is marked in advance, while the mark is made at the level at which the casing pipe exits.
The pipe head is secured to the casing using reinforced plumbing tape.

Possible installation errors:

When laying pipes to the house, a certain length reserve is not taken into account, that is, bends and turns are not taken into account, and possibly the thickness of the foundation through which the pipeline will pass.
The threaded connections are not tightened with a wrench. Simply sealing and tightening by hand is not sufficient. During operation, water leaks are possible.
The hydraulic accumulator was not given due attention. If the pressure drops below 1.2-1.5 atmospheres, then it needs to be increased using a compressor or car pump.

Option #2 - connecting to a water supply

The need to connect a pumping station to a centralized water supply usually arises when there is not enough pressure in it for the correct operation of heating equipment. This, in turn, can be caused by several reasons:

changed hydrogeological conditions;
outdated equipment;
increase in water consumption due to population growth, etc.

It is important to note here that before connecting the pumping station, you need to take care of purchasing and installing a storage tank.

So, the algorithm of work:

The water pipe is disconnected at a predetermined location.
The end, from the city highway, is connected to the storage tank.
From the tank, water is directed to the pump inlet, and the end of the pipe leading to the house is connected to the outlet.
Electrical wiring is being installed.
Setting up/adjusting equipment.

Setting up a pumping station is primarily aimed at setting the optimal pressure in the system. To adjust the equipment, first about 2 liters of water are poured into the snail through a special hole. Now you need to track at what stage the pump turned off, and then when it turned on. Shut-off pressure – 2.5-3.0 bar, switch-on pressure – 1.5-1.8 bar.

If it is noted that the station turns off earlier than necessary, it is worth reducing the pressure created. In general, setting up the equipment is quite simple. You need to open the relay cover and turn the screw marked “DR” towards “+” or “-”. And to specifically regulate the switching pressure, a screw marked “P” is used.

Another detail that should definitely be taken into account before properly connecting the pumping station is the chemical and physical characteristics of water. Regardless of the source of water supply, it contains harmful impurities that must be eliminated before the water reaches the pumping station. The simplest and most effective way to solve this problem is to install a station on the suction device.

What happens if you don't install a filter? Mechanical impurities in the form of sand, clay, etc. will gradually accumulate in the hydraulic accumulator, which will ultimately lead to breakdown of the pump, which is an integral element of the pumping station. This problem is especially relevant when using a vibration pump.

On the other hand, one cannot help but focus on the negative aspects of installing a filter. Thus, additional resistance to the flow of water is created, the created pressure and pressure are reduced. To avoid such problems, the filter must be constantly cleaned. And a situation may arise when a dirty filter does not allow water to pass through it at all, which can cause the pump to fail.

By installing a pumping station yourself, you can save significant money, which will be used to purchase truly high-quality equipment. And this, along with proper installation and configuration, will allow you to forget for many years that there may be any problems with the water supply system. We would like to draw your attention to the fact that you can not only buy the station ready-made, but also assemble it yourself.
