The connection of the two components in the well (cut)
Now we can proceed to the main and final phase of the pump installation – for this we will not be able to do without the rod, which is wound on the inside of the adapter – this part is clearly visible in the photo, which shows how the adapter is disconnected – something like a black bowl on top.
So, now you need to first immerse the pump in the pipe, hold it by the flexible polyethylene pipe, and then continue diving with the help of the rod – immediately make a mark on it so that you know whether the inside of the adapter has reached the outer part (the mark on the rod is the outer part of the pipe). Most likely, you will not be able to get into the grooves from the first time, but this is not a reason for frustration, make a few more attempts and you will definitely get.
Note. As an auxiliary rod, you can use the same PND pipe with a compression fitting – fasten the fitting to the attachment point (black bowl), and then attach the pipe to it.
Only the HDPE must be fixed tightly, and screw the fitting to the adapter not to the end, so that it is easier to remove after installation.
The cable that is attached to the pump for fixation, fasten to the tip of the tightness, so that the pump is held on him, and not on the adapter or electrical cable. The electric cable can be attached to the terminals on the top, but you can simply release it into the trench, bypassing these terminals – you still have to increase it, since it will not be enough to the building.
Water supply to the house
32mm polyethylene pipe (HDPE)
We screw on the adapter a compression polyethylene sleeve for the pipes and fasten the HDPE pipe to the other end of it, which we deploy along the trench all the way to the house, just need to make a reserve for input.
By this time we should have a trench with a sand cushion and a hole under or in the foundation tape, as well as a pit in the room. The caisson in the house is usually bricked up and then plastered, but sometimes concrete rings or even a wide plastic barrel are used for this purpose.
So, let us imagine a conditional situation, that we have already brought a polyethylene pipe and an electrical cable into the caisson, which was equipped in the room (it’s too early to fill the trench – this is done only after the tests). Now we are interested in the further water supply scheme at the dacha from the well, and immediately after the HDPE of the pipe we install the main valve (the heating cable does not count, it is optional), after which the coarse filter cuts.
The upper photo shows that further, according to the scheme, a block is connected with a pressure switch and a dry-running sensor, although the author of this article came to the conclusion that it is better to buy a sensor and a relay separately – this prolongs their operational life. In any case, only one device can fail, but not the entire unit.
The cable from the pump and the cord that goes to a 220V power outlet are connected to the relay terminals, but you can not install the dry-running sensor, but it serves to automatically turn off the pump if it does not pump water, that is, it works dry.
It looks like a pumping station in the pit (caisson)
A membrane tank can be embedded anywhere, that is, before the relay or after it, it does not matter, since in any case pressure will be created in the tank itself and in the pipe section from the check valve to the water distribution stop valve. The larger this tank, the less frequently the relay to start and stop the pump will operate, as the reserve pressure will increase, but this capacity should not be more than 100 liters.
In addition, the mode of starting and stopping the pump depends on the settings set on the pressure switch. In the factory version, the start is triggered at a pressure of 2 atmospheres, and a stop at 3 atmospheres. But you can expand this range by setting the start to 1.5 atmospheres, and stopping to 5 atmospheres. By increasing the gap, you reduce the number of starts and stops of the engine, which increases its operational life.
After the final assembly, the water supply system at the dacha needs to be tested and if everything works fine and there are no leaks anywhere, you need to fill the trench and seal the pipe entry point to the foundation with cement mortar or tile glue so that soil moisture does not get into the room. The pipe is first covered with sand to cover it by 5-8 cm, then it is poured with water to shrink the sand and cast over with soil.
The device of a water supply system from a well in the country
- Main advantages
- Additional elements
- Filters used
- Automation and hydroaccumulator
Currently, there are many different types of water systems that can be installed at the cottage. All of them are highly efficient. Separately there is a water supply from a well in the country. This system is completely autonomous, so more and more people prefer it for their country houses and land.
The general scheme of water from the well.
Doing water at the cottage from the well is quite difficult. However, in this case nothing is impossible. To work, it is worthwhile to acquire additional patience and manpower, because by itself it is not always possible to carry out the whole range of activities. Water supply of suburban areas reaches a new level thanks to the use of wells for these purposes.
Creating a water supply system using wells carries a number of positive points:
The scheme of water supply at home.
- a huge supply of water, that is, liquid is drawn from the bowels of the earth, here its supply is infinite;
- since water is taken from a depth, it has an increased chemical and physical purity;
- the possibility of obtaining virtually any amount of water for all their needs;
- long service life, which can be 50 years or more.
It is worth considering the issue of water supply in the country with the help of a well in more detail. In this case, we will focus on the well in which the submersible pump is mounted.

Today, all the wells that serve to organize the water supply system in the country can be divided into two large groups – artesian and sand. At the same time, sand wells can go down to a depth of 30 meters and provide water in the amount of approximately 1.5 cubic meters per hour. The second option can be recessed as much as 70 meters. The volume of water is about 10 cubic meters per hour. Plumbing in the country is organized by both methods.
Sand wells have one very significant drawback, which makes their use for organizing water supply at a dacha limited, namely, they are very often contaminated due to sediment or other substances. Artesian wells should be used in conjunction with a filter to clean water from iron and other heavy elements. In this case, a specific type of filter is selected only after a thorough biochemical analysis of water has been carried out. The installation of an artesian well also entails a number of inconveniences. There are often established groups of filters from which it is quite problematic to drain the water before the preservation process is carried out.
However, the water supply system from the well has recently been considered the most optimal option for the dacha.

Diagram of a submersible pump.
Today, all the wells that are used to organize the water supply at the dacha are equipped with a pipe, which is selected in accordance with the diameter of the system itself. A cap is mounted on top, which prevents various small particles of dust and dirt from entering the well.
Water is pumped out of the well by means of a submersible pump, which is selected on the basis of the parameters of the well itself, and also based on what needs exist for a person living in a country house.
The pump itself, along with the hose and cable, is quite heavy. Sometimes, in order to immerse it to the required depth, it is necessary to use special lifting mechanisms. In this case, the winch is perfect. She may well cope with the task. In addition, you can additionally install two coils, one of which will be twisted cable, and the other hose.
It is better to equip the water supply system at the dacha in cases when it comes to year-round living on it. In this case, all systems will work stably. If accommodation will occur only in the summer, you need to think about how to think of other methods of organizing water supply on your site.
Currently, most often for the supply of water directly to the house is organized water supply system, which is based on polypropylene pipes. They have excellent operational characteristics, are not subject to rusting, are not subject to the influence of harmful aggressive chemical environments. Great solution for any water system.
If the water supply system at the dacha will be operated exclusively during the warm period, then laying the pipes to too great depth does not make sense. Here you can confine 1 meter depth. However, it is worth remembering that it will be necessary to drain all the water from the system in the fall. When laying pipes it is worth remembering that all pipes should be mounted at a certain angle to the well. And the slope should be in her direction. This ensures complete purification of the water supply system from excess water. This completely eliminates the possibility of rupture of the water supply system during the winter period.
Scheme suburban plumbing.
In order that even before the onset of frost it was possible to drain all the water from the system, it is necessary to install a special drain solenoid valve. In the event that the water supply system in the country will be operated all year round, it is necessary to lay the pipes to a greater depth. It should exceed at least 20 cm in depth of soil freezing. In this case, they will be fully protected from external weather conditions. It should be remembered that the depth of soil freezing is not the same in all areas of the country. First you need to do a study of this phenomenon.
It is not always advisable to lay pipes to a depth of more than two meters. This phenomenon can be avoided. For this purpose, special heaters are used, which are mounted on the outside of the polypropylene pipe. Such insulation is now quite widespread. They perfectly protect pipes in the winter. In this case, the depth of the bookmark can be made significantly less than originally intended.

As noted earlier, following the submersible pump, special cleaning filters should be lowered into the water. Of course, not all models that are on the market are suitable for any given situation.
All filters are selected according to the type of water that prevails in this area.
Well water filtration system.
In that case, if we are talking about using an artesian well for organizing water supply, it is necessary to install an iron cleaning filter without fail.
If the depth of the well is not so great, then you can use filters that limit the flow of small mechanical particles into the pipeline. Any filter must be installed before the accumulator. In this case, its contamination with sand and other particles can be excluded. Cleaning the accumulator itself is very difficult. In any other places in the system, filters must be installed in such a way that they can be easily reached. In this case, they will be easy to clean and change.

Automation and hydroaccumulator
Automatic water supply eliminates the likelihood of hydro-shock.
The automatic water supply control system ensures the stability of the entire water supply system, eliminates the likelihood of a water hammer, and helps optimize pump operation in the system in order to ensure optimal cycles of its on / off.
Here we are talking about the installation of two types of control relays. The first relay is a pressure switch that turns on the engine when the pressure drops to a certain value. The second relay is the idling relay. Due to the fact that the pump will turn on and off with the slightest leakage of water from the system, it may soon fail. He will begin to wear bearings and the shaft itself. Naturally, the submersible pump is a very complex mechanism, which costs a lot of money. To compensate for its operation, it is necessary to install a hydroaccumulator in the system.
The accumulator is a tank, which is divided into two parts. In one of them is a liquid, and in the other air. At the same time, both sections are separated by a special waterproof membrane. Air pressure in this case can have the most various values. Its parameters can be adjusted using special controls.
The principle of its operation is quite simple. Water from the system is first drawn into it. At the same time, the air, which is located in its other part, is gradually compressed to a certain value, which is established using a pressure switch. After the fluid pressure reaches its maximum, a pressure switch is activated, which shuts off the pump. After that, the liquid gradually begins to be spent on the needs of the consumer. At the same time, the air pressure gradually decreases. It falls until it reaches a certain set value. After that, the pump will turn on again.
Back to table of contents
In order for the water supply system from the well to work normally, it is necessary to ensure it with a sufficiently large number of the most diverse valves and fittings. Shut-off valves will limit the flow of fluid into the pipeline during a certain period of time, and fittings are necessary to ensure tight connections.
Stop valves are needed to limit the supply of water in the cold season.
Valves here can be very diverse. It uses both large valves, and various types of valve. They will ensure the stability of the system. Quite a lot of similar valves and valves in the house should be installed. They must be installed in each riser and ensure reliable preservation of the system during the winter period, if it is not actively used at that time. Fittings are called connecting elements of the pipe system. They are needed to connect all the polypropylene components of the pipeline.
The well itself is digging with the help of special equipment. It’s not possible to organize a similar water supply system in the country or in a country house. Sometimes in winter it is necessary to organize the supply of hot water in his country house. This is done using a similar water system. In this case, another element is added to it, which is called an electric water heater. It is installed in it and is connected to the power supply network. Water heaters can be very diverse.
Often, to obtain hot water in the summer cottage, a relatively small volume of this device is sufficient. Moreover, its power can be very diverse. Here, all the parameters will directly depend on the number of people who permanently live in the holiday home.
Thus, the organization of water supply cottages with the help of wells is an excellent option that should be used everywhere. Of course, it is very difficult to install such a complex system on your own, so in any case you will have to turn to professionals. Installing wells with all the equipment today is not so expensive to indulge in the pleasure of constantly having cold and hot water at the dacha.
Here you should not forget about the additional mechanisms that should always be included in the package. Be sure to install various filters. They will help protect your body from various heavy substances that may be hidden in the bowels of the earth. These filters can be very diverse in their structure. However, their use is mandatory.
In this case, we cannot do without automatic systems for regulating water supply. Here it is necessary to install additional control relays that will regulate the flow of fluid into the house. Without such a device as a hydroaccumulator, not enough. It will regulate the flow of fluid with frequent switching on and off of the water supply system. Without it, the submersible pump will not be able to withstand frequent on and off cycles for a long time.
How to make water in the country of the well: the device and the equipment used
In the absence of a centralized water supply system or serious interruptions in its work, you can equip an autonomous system in your household. A well or even a spring can become a source of water for it, but, as practice shows, most often the water supply system is installed in a country house from a well. Such an option, provided that there is a competent arrangement, can be considered the most effective, practical and economical.
What are the wells
A well is the production of a circular section, drilled without human access to the face. The diameter of such development is always much smaller than its depth. For the implementation of water intake uses two types of wells.
Filter or “wells on sand”
The depth of such workings does not exceed 35 m. They are drilled on the closely lying aquifer, which is located in sandy soils.
Such a well is a casing assembled from pipes with a diameter of 127 to 133 mm. It is usually equipped with a bow filter screen, but there may be other options. Filter wells have a small debit, most often it does not exceed one cubic meter of water per hour.
The construction of the well on the sand is much simpler than the structure of the well on the limestone. The depth of sand production is less, it costs less, but it does not last as long as a well for limestone (click for larger image)
The advantage of such structures is the speed and relative cheapness of their drilling. Experts will cope with the work in just a day or two. The main disadvantage is the silting tendency. Therefore, it is very important to use such a well regularly, the life of the structure depends on it. Depending on the power of the aquifer and the intensity of use of the well, it can last up to 15 years, in some cases even longer.
Shallow borehole in the country can be drilled with a manual machine. It will provide water for irrigation and sanitary needs of summer residents.
For the device of a water source with a fence from a depth of 20 – 30 m it is better to use a small-sized drilling rig
Drilling by small-sized installation
If development deeper than 20–30 m is required, drilling and drilling services will be required for its development.
Drilling with specialized equipment
With the pumping of water from a shallow well, punched or drilled by hand, a surface pump will do well
Well needle with pump
In order that the pump does not have to constantly shut off, disconnect and carry into the house after pumping, it is advisable for him to arrange a pit or build a pavilion
Borehole equipment with surface pump
The mouth of a deep well is most often located in the pit or in the caisson. A submersible pump is used to pump water out of it.
Deep hole pit
Caisson for deep development with a submersible pump can be made from concrete rings, used plastic barrels or broken bricks
Caisson from a concrete ring
If a caisson is not suitable for the arrangement of a well, it is necessary to protect its mouth with a sealed tip that prevents dirt from entering the barrel and pump theft

Artesian or “wells on limestone”
Deep structures that are drilled to the water carrier, common in fractured limestone. It is about 20-130 m deep. Unlike wells, artesian sands have a higher debit. It can reach up to 100 cubic meters of water per hour. Drilling wells for limestone is quite difficult, and the casing has a considerable length. The drilling procedure lasts four or more days.
The figure shows a scheme of an artesian well, which is characterized by a large water flow and long service life.
Accordingly, the cost of work and materials is significantly higher. The advantage of artesian wells is their long life. They do not need a filter, because the host rock does not contain small clay and sand particles. Thus, the silting of the well does not occur, because it can last much longer than the filter, five dozen or even more years.
What pumps work in wells
The pump is a kind of “heart” of the system. The uninterrupted work of the future water supply system depends on the correctness of its selection. On sale you can find several types of pumps submersible and surface categories. The latter are called this because the pump itself is removed from the pumped liquid. The body of the unit is located on land, and the water intake is performed by a hose lowered into the well.
Surface pumps can extract water from an average depth of 8 to 10 meters, so they are rarely used for wells. Most often, submersible devices are installed for water supply. Their main difference from the surface – full immersion. Their design is specifically designed for large depths, where they are used as efficiently as possible.
Submersible borehole pumps are divided into two types. In the case of centrifugal devices the shaft is mounted on which paddle wheels with blades are fixed. When the shaft begins to rotate, the movement of the blades creates a centrifugal force that pumps the fluid that fills the interior of the device. Taki pumps are reliable and versatile to use.
Surface pumps can work at depths of no more than 8 -10 meters, therefore, they are rarely used for well construction.
In addition, centrifugal mechanisms are distinguished by an optimal price / quality ratio. Vortex pumps are considered the most practical option. In addition to low cost, they attract the utmost simplicity of design and unpretentiousness in operation and maintenance. The basis of the device is a membrane, on one side of which there is a liquid, on the other – a vibrator.
After switching on, the latter starts to move and causes the membrane to deform, thereby creating a pressure difference. Which, in turn, starts the process of pumping fluid. The mechanism is devoid of rotating elements and bearings, which are particularly vulnerable and require constant monitoring and lubrication. The absence of rotating elements significantly reduces the heating device and prolongs its life.
For artesian wells, a special deep well pump will be the best choice. They are specifically designed to work at great depths where surface pumps, even if equipped with an ejector, cannot function. The installation of the depth gauge is rather complicated, as well as its dismantling. Properly selected and installed high-quality device will work for decades.
For work at great depths, submersible pumps are used, which are lowered into the liquid and function inside the well.
A cheaper counterfeit with such a load is unlikely to cope and will require repair. However, it should be understood that in the case of a submersible pump, the cost of only dismantling it can be quite comparable with the cost of the device. Therefore, it is necessary to purchase only high-quality device.
Automate the supply of water to consumers can even for a system of temporary country use. To do this, you need to put an automation unit in front of the pump
Automation suburban water supply
For laying of a summer water supply system, PND pipes with fittings for them are suitable. However, such a system should be drained, dismantled and cleaned for the winter.
HDPE pipes in the water supply system
Automatic water supply to the water supply will be provided by the pump control unit, which turns on the unit when the pressure drops and shuts off when exceeded

To prepare water for use in the autonomous network include filters for coarse cleaning and disinfection.

How to choose a pump
Experts identify several criteria that must be taken into account when choosing a mechanism.
Total well depth and water level
Key characteristics when choosing a pump. The technical documentation must indicate the optimal depth for which the device is intended to work. If this requirement is not observed, the device will work inefficiently and can quickly fail. In the passport of the well should be indicated and its depth and water level. They can only be compared with the characteristics of the pump.
If there is no such data, you can use a very simple way to measure the depth of the structure. We take a long dry rope, tie a small weight on its end and lower it into the well. Pull the rope down until the weight touches the bottom. Remove the cable. We measure the dry part – it will be the distance from the top to the water level. The wet part is the height of the water column.
Approximate well debit
This is the name for the mass of water that can be obtained from a well over a certain period of time. In the passport drillers indicate this value, but if not, we conduct approximate calculations. We completely pump out the water from the well and measure the time during which we did it. Then we measure the time during which the well is filled with water. We divide the second result into the first one and get an approximate debit, which will be enough to choose a pump.
Pumps have different performance to choose the right model, it is important to correctly determine the daily need for water
Estimated Water Requirement
Different pumps can supply water at speeds from 20 to 200 liters per minute. In order not to overpay for a more powerful model, it is important to correctly calculate your own need for water. On average, it is believed that one person needs about 200 liters of water per day, so a family of three or four people needs a pump with a capacity of 30 to 50 liters per minute.
Some people prefer to take the device with a “margin” of power, which will inevitably affect its cost. If it is planned that the pump will work not only for servicing household needs, but also for watering, an increase in its capacity should be calculated. It will depend on the size of the site, but on average should be about 2000 liters per day. Therefore, it is necessary to increase the need for water by 40-50 l / min.
Required water pressure
In the passport of the pump must indicate the pressure. To calculate the required head, we add another 30 more to the depth of our well, expressed in meters. Thus, we will get the height of the water column. The result obtained is increased by another 10% and we obtain the desired value. Comparing it with the pump data, choose a model. If there is no exact match, “move” upwards.
The diameter of the pump must exactly match the diameter of the drilled well, otherwise you will not avoid problems with the installation and operation of the device
Diameter of drilled well
Another important quantity that determines pump power. Like others, it can be taken in the well passport or measured independently. It should be noted that the diameter of the well must be expressed in inches, where the inch is 2.54 cm. The vast majority of pumps are designed to work in 4-inch wells. For 3-inch, you will most likely have to order the pump in the catalog.
Choosing the right equipment
For arranging the water supply from the well besides the pump, we will need other special equipment necessary for the normal functioning of the structure.
Sealed tank to protect the tip
An important structural element for well development is a caisson. This is a sealed chamber in which is located the tip of the well. It protects the structure from freezing in the cold season and from the penetration of groundwater. In addition, inside the tank is all the necessary equipment for the functioning of the well. Therefore, the size of the caisson should be sufficient to fit inside the devices and descend for maintenance or repair people.
Caisson reliably protects the wellhead from low temperatures and groundwater. Here you can place all the necessary equipment.
The hermetic chamber can be made of different materials: plastic, concrete, metal, brick or polymer sandpaper. Each of the options has its advantages and disadvantages. The shape of the container can be any, but most often it has a circular or quadrangular cross-section. The caisson can be bought off-the-shelf or manufactured by yourself. In any case, the tank should be equipped with a hatch with a tight lid.
The device is a container divided by an elastic membrane. One of the resulting compartments is filled with air, the second – with water. The water entering the tank stretches the membrane, thereby reducing the volume of the first compartment. The more water, the higher the pressure in the first chamber. After the consumer opens the tap, the amount of water decreases and the pressure in the air compartment decreases.
The accumulator is equipped with a sensor that monitors the pressure in the chambers. When it falls below the set point, the device sends a signal to turn on the pump and water from the well enters the system. As soon as the pressure rises to a certain level, the pump turns off. A hydroaccumulator is used to create enough pressure in the water line to operate household appliances.
The accumulator is necessary to protect the pump from premature wear, in addition, it creates the system pressure necessary for the operation of household appliances
Some of them, for example, instantaneous water heaters, dishwashers and washing machines need a pressure of at least 0.5-0.7 atmospheres. In addition, the device protects the pump from premature wear. Without the accumulator, the equipment will turn on too often. And this is extremely undesirable for him, because turning on a pump more often than 10 times per minute increases its wear by 40%.
Filter system for water treatment
Filters are necessary for wells of any type. Even deep artesian “give out” water with a high content of iron, heavy metals and other unhealthy trace elements. Therefore, the purification of such water is necessary. It is possible to pick up the necessary type of the filter only after carrying out the water analysis. A complete cleaning system in the maximum configuration will look like this:
- Strainer strainer. It is placed in front of the pump and in front of the hydroaccumulator.
- Filter mechanical cleaning. The device delays inclusions in the size of 80-100 microns. Represents a flask with a replaceable fibrous filler.
- Aeration block. Oxygenates the water that passes through it.
- A set of special filters. Each of them eliminates the excess of a specific element: iron, potassium, sodium, salts, etc.
- Biological protection unit. It is a carbon filter or ultraviolet emitter that removes microorganisms from water.
- Fine filter. Stops inclusions up to 5 microns in size, which completely eliminates precipitation and impurities from the liquid.
As a supplement, a reverse osmosis filter can be installed, which allows to obtain drinking water of the highest quality.
The figure shows schematically one of the options for constructing a water supply system from a well (click to enlarge the scheme)
Technology arrangement plumbing system
After all the necessary equipment has been purchased and the well has been drilled, you can proceed to the construction of the water supply system.
We pull water from the house to the well
We determine the area on which the pipeline will be located, and proceed to digging the trench. Its depth should be greater than the level of soil freezing in this area by 20–30 cm. This is a very important requirement. Its failure threatens to freeze and destroy the system during the cold season. We lay a sand cushion on the bottom of the excavated trench; on it is a 32 mm water pipe made of cross-linked polyethylene or metal-plastic.
Alternatively, you can lay a PD pipe, but it collapses when frozen, which cannot be excluded. Some “experts” instead of the pipeline laid in a trench hose for supplying water. If you do not want to get problems with the operation of the water supply, you should not do it. Particular attention is paid to the pipeline lifting section to the house. Be sure to warm the foundation and wrap the pipe with a special material.
It is possible to use a self-regulating heating cable for insulation, which is laid along the pipe at the lifting point. The same method is applied in the case when, for any reason, it is impossible to carry out land work on the site. Then dig a shallow trench under the pipe and put them together with the heating cable. Elements are wrapped with insulating material and placed in a pipe of a larger diameter.
The trench for water pipes must pass below the level of soil freezing. otherwise in cold weather the system will be corrupted.
In addition, the cumulative capacity for irrigation can be added to the resulting system. Because warm water has a beneficial effect on plants. When laying the water pipe, we do not forget to lay the cable that supplies electricity to the pump. It must be four-core and have a cross section of at least 2.5. The ROM box is placed in a specially designated place in a heated room.
Correctly install the caisson
Installation of the caisson depends on what material the container is made of. The easiest way to install plastic and polymer sandwich containers. In any case, first we prepare the pit, which should be larger than the camera itself. In some cases, at the bottom of the pit we mount a concrete pad. Then set the caisson in place and level by level. In the case of a plastic container, we also fasten it.
Self-made concrete chambers are assembled from rings or poured into formwork assembled on site. Brick tanks laid out directly in the pit. At the end of the work in the caisson we start water pipes and cable, the input sections are reliably sealed. We lower and install the equipment for the well. If necessary, we carry out the backfilling of the installed caisson.
We lower the pump into the well very carefully and carefully. Through every meter and a half we fasten to the water pipe the electrical cable, the feed pump.
We mount and connect the pump
Before starting the installation of the mechanism it is necessary to familiarize yourself with the recommendations of the manufacturer. We start with cleaning the well. We pump water out of it until the sand and other particles of pollution stop coming out. To fix the pump in the borehole, use 4 mm steel cable of the desired length or 5 mm nylon cord. Securely fasten it to the case. In addition, we connect the pump with a water pipe.
We perform all operations very carefully, so that subsequently the pump does not get stuck in the casing. For the normal functioning of the system, a check valve is necessary for the pump, which will not allow water from the pipeline to return to the well. Some models are already equipped with such a device, if not, install the node. We put on the lower part of the tip with a seal on the well pipe.
Step 1: Before immersing the submersible pump into the well, a fitting is connected to its branch pipe to connect the pipe and a check valve.
Preparation of the submersible pump for installation
Step 2: A pipe for pumping water to the pump is more convenient to connect near the well.
Water pipe connection
Step 3: The pump is gently immersed in the shaft, taking into account the extreme distances from the bottom and from the water mirror specified by the manufacturer
Diving pump into the wellbore
Step 4: After diving the pump to an acceptable depth and testing the autonomous system performance, the well is equipped with a headboard
Construction of a dacha well

Construction of a dacha well
Now you can gently lower the pump into the well. We do this carefully, without jerking and do not forget to fix the electrical cable, the feed pump, to the water pipe every meter and a half. The wire must lie free, without tension. After the pump touches the bottom, raise it to a height of one to three meters and fasten it. Now set in place the upper part of the tip.
We connect to the plumbing and electrical cable all equipment located in the caisson: water purification system, valves, automation, etc. In the course of the work, we precisely fulfill all recommendations of the instrument manufacturer. After connecting, we once again check the reliability and tightness of the connections of the water supplying pipeline and the electrical safety of the newly assembled system.
The casing head is designed to seal the structure and protect it from dirt, debris and foreign objects.
Install and connect the hydroaccumulator
The volume of the hydroaccumulator can be very different: from 10 to 200 liters. Depending on it, the place where the equipment will be installed is selected. This can be either a caisson or a basement at home. When choosing an installation site, it is necessary to take into account the need to ensure free access to the device for subsequent maintenance, repair, or possible replacement of a failed container.
During the installation of the hydroaccumulator, a check valve is necessarily installed to prevent water from flowing from the plumbing system to the tank. It is placed in the direction of the fluid. Mounted and drain valve designed for emergency discharge of water from the tank. To reduce the level of vibration from a working device, we mount it using a special rubber seal.
Filters – a mandatory element of the arrangement of water supply. They make well water suitable for domestic use and drinking.
We connect the water supply pipe to the accumulator. We assemble the starter that will power the pumping equipment. We connect a sensor to the hydroaccumulator, which will control the pressure in the compartments of the tank, and feed the starter through it. We connect the hydroaccumulator to the internal water supply system, directly or through a collector.
We carry out a test run of the system
After the installation and connection of all elements of the system have been carried out, it is possible to proceed with its test run. First, we activate the pump and, if necessary, debug its work. Then we fill the storage tank with water and check the accuracy of the automatic start and shutdown of the pump. Then carefully inspect the entire pipeline.
We need to identify possible leaks. If there are any, we carry out repairs. In addition, we check the work of all plumbing devices connected to the water supply. Pay attention to the performance of the system: the water pressure should be normal even with all open taps. If the test run was successful and the system works without failures, bury the trench, supplying water from the well to the house.

At the country house without water as without hands, it is hard without the usual benefits of civilization. So if there is an opportunity, you need to immediately arrange a plumbing system. This year I spent water in my summer cottage. Of course, not everything went smoothly, as I thought. There were problems with the well, as it turned out very deep and my pump, which I bought at first, did not pay off. Power is not enough, he pumped weak water. But then I found a solution. For me the information was useful, I got all the answers for myself.
Interested in a few clarifying questions. First, I ask you to tell me whether such installations always give a good pressure or is it all individually and depends on the area? Secondly, even if the pressure is good, is it enough for a large household, say 300 m2? And thirdly, what are the energy costs of the installation, do you really have to pay a lot for electricity as a result?
