The choice of a pumping station for a summer residence is a rather difficult and important task, since many summer cottages are not connected to the city network, therefore summer residents use wells and wells, from which water is supplied using pumps. This has certain nuances, pros and cons, which we will consider in detail.

The main task performed by pumping stations for a well in the country is to create sufficient pressure in the system, so that water will flow with a good pressure, regardless of how far or high the taps are. That is why it is required to choose the right pumping station, calculating its power and the volume of liquid that will need to be supplied.

In order to understand how a pumping station for a summer residence works, you need to know first of all what is included in it. This is a pump of a certain power, an expansion tank, control devices, so that the structure can work automatically and does not require constant switching on and off from the mains.

Choosing a pumping station for a summer residence

There are different types of pumps: some are suitable for irrigation and have low power, others are used in stations and help to supply water to the house, sometimes it is the second and even the third floor, so the pressure should be much higher than in the irrigation pump.

Water supply can be carried out as follows:

• The pump is turned on only when necessary, it has no automatic control and supplies water immediately after it is turned on. This option is suitable for watering or if you live in the house fickle and rarely need water.
• The pump pumps water into a storage tank located at the top of the house. Thus, there is always a certain margin that reduces the dependence of the owners on the stability of the electricity supply. A non-pressurized storage tank can be used, for example, as a summer shower. A switch can be installed on the pump itself. This method will not allow the use of household appliances, such as a washing machine, as it requires a good water pressure.
• Using a diaphragm accumulator and a submersible pump. This method is more convenient, but also not devoid of disadvantages.
• Installation of an automatic station. Such a pumping station in a well for a summer residence allows the water supply system to work autonomously, while using a membrane reservoir, you can create a supply of water that will be issued under pressure. In addition, the system does not require constant switching on and off of the pump, the automation will do it itself, the main thing is that the equipment is connected to the power supply. In fact, everything will work in the same way as in a city apartment. As soon as you open the tap, water flows, close it - it doesn't; nothing else needs to be done. Such a system is equipped with a special relay that regulates the pressure so that it does not click, a membrane tank is used, which maintains the required pressure inside the system. This helps to reduce the load on the pump, increase its resource, and reduce energy consumption. Automatic pumping stations for summer cottages are the best option, since they are not only more convenient to use, but they also save electricity consumption.

When laying a pipeline to a house, it is necessary to take into account the depth of soil freezing. For the Moscow region, this is 1.7 meters.

In order to be able to raise water from a well or well, provided that it no longer has large impurities, a surface pump is used. Especially with a great distance from home, it is recommended to install a Vodomet type pump (with a float protection) directly in the well. Pumps for a well must be protected against dry running, this is a float switch. Be sure to make sure that the pump does not sink to the bottom of the well and does not suck in sand with its blades. additional filters are installed in the house.

In addition, the system includes a check valve, its task is to prevent water from falling down if the pump stops working. At the outlet, a valve is usually also placed, before entering the taps, water can pass through a removable filter; it is usually installed in the home. A splitter is placed after the filter. A membrane tank, a barometer relay are connected to the system, after which the system is connected to the power grid.

Design features

Different manufacturers can arrange the elements in their own way, the relay, for example, can be equipped with flexible wiring or not, its landing place can differ, but in general the system includes the same elements. Differences can also be caused by the type of pump; the devices may differ at different stations. This is also due to the peculiarities of the operation of the device

• Most often, surface pumps are used, they have sufficient power, are inexpensive, and are easy to use. The downside of such a device is its noise and the ability to raise water only 6 meters, but for a small private house this is usually a sufficient height.
• A self-priming pump can have a built-in ejector: this is a device that allows you to take water from a depth of 15 meters, it is suitable for shallow wells and deep wells. The device is noisy.
• If the well is deep, more expensive equipment with an external ejector has to be used.

If you force the water to circulate through an external ejector, the suction depth can be increased to 45 meters, which is quite enough for servicing a standard well. It will also be possible to deliver water over a considerable distance. The equipment is quiet, but consumes a lot of energy.

If the source is not deeper than 10 meters, you can use multi-stage equipment, it will create a powerful head, while working without unnecessary noise. The difference between such a pump is that it is equipped with several chambers and impellers. There are pumping stations with vortex pumps, the device has a relatively low capacity, is capable of creating high pressure in the system, supplying water under good pressure. Such a pump can supply water from a well no deeper than 7 meters, therefore it is most often used for wells. The advantages include efficiency and minimal noise during operation. Such a pump can also be used for central water supply, if the pressure in the line is weak, it will help to increase it.

The pumping station can be placed inside the well, if there is a place for this, in addition, utility rooms in the house itself or in the room are often allocated for it. Pay attention to the depth at which the pipeline will be. The pipe needs not only to be insulated, but also to be placed below the depth of soil freezing so that the water in it does not freeze in the cold season.

In order for the system to work correctly, you need to choose not only the type of pump, but also the depth at which it will work. The deeper the water source and the further away from the building, the more powerful the pump itself must be. At the end of the pipe there should be a filter, it is located between the pipe and the pump, protects the latter from debris entering the mechanism.

The devices usually write the depth to which they are designed, but it is worth taking a more powerful one, since the calculation is carried out only from the bottom of the well to its surface, not taking into account the distance to the structure. It is easy to calculate: 1 meter of the vertical position of the pipe is 10 meters of its horizontal position, since it is easier to supply water in this plane.

Depending on the type and power of the pump, the head can be higher or lower. It can also be calculated. On average, the pump provides 1.5 atmospheres, but this is insufficient pressure for the normal operation of the same washing machine or hydromassage, the water heater may require a higher temperature.

In order to control the pressure, the equipment is equipped with a barometer. The size of the storage tank is calculated depending on the pressure parameter. The productivity of the station also plays an important role. This parameter indicates how many cubic meters per minute the pump is capable of delivering. You need to calculate based on the peak water consumption, that is, when all the taps in the house are open or several consumer electrical appliances are operating. In order to calculate which pumping station for giving into the well is suitable, you need to find out the performance. To do this, add the number of water supply points.

From the point of view of power supply, it is more convenient to use those systems that are powered from a 22 Volt network. Some stations operate 380 V phases, however, such motors are not always convenient, because three-phase connection is not available in every home. The power of a household station can vary, on average it is 500-2000 watts. Based on this parameter, an RCD and other devices are selected that will work in conjunction with the station. In order to prevent the structure from overheating, many manufacturers install automation that will turn off the pumps in the event of an emergency load. The protection is also triggered if there is no water in the source, when voltage surges occur.

How to calculate the volume of a hydraulic accumulator?

The size of the tank determines how often the pump motor will turn on. The larger it is, the less often the installation works, which saves on electricity and increases the resource of the system. A hydroaccumulator that is too large takes up a lot of space, so they usually use an average in size. It holds 24 liters. This is enough for a small house where a family of three lives.

If up to 5 people live in the house, then it is better to set the tank to 50 liters, respectively, if more than 6, it should be at least 100 liters. It is worth noting that the standard tanks of many stations hold 2 liters, such a hydraulic tank can only cope with water hammer and maintaining the required pressure, it is better not to save money and immediately replace it with a large one. It is the number of water users in the house that will determine which pumping station to choose for the summer residence.

Water purification

Do not forget that the water from the well, even if it is suitable for drinking, may have impurities, for example, sand, small stones and various debris can get into it, which can be disposed of using a special system for water purification. Filters are most commonly used. They are placed outside in order to make them convenient to change. They can have a different fraction and purify water to varying degrees. At the outlet, filters of deep fine cleaning are used.

Models

There are many models of pumping stations on the modern market. They differ not only in properties and quality, but also in price. It is recommended to buy products from well-known companies that provide a guarantee of the quality of their products. You can read reviews about them, choose a suitable model with the help of a company specialist who will help you calculate everything you need. These brands include the following:
