Selection and installation of water pumping stations for home and garden
Providing a private house or country house with water is one of the most important components of comfortable living outside the city. In the absence of a centralized water supply, there is little. For the smooth operation of the water supply system, it is mandatory to have a water pumping station in it, which will provide water supply to each of the water intake points. Choosing the right unit for home plumbing is easy. It is important to take into account all comments and reviews regarding each of the water stations for a house or a summer residence.
The design and principle of operation of the pumping station
The main task of the pumping station is to provide residential buildings and adjacent land with water from artificial or natural sources. It is these units that help fill additional tanks intended for watering the garden or garden plants, as well as provide traditional water points with water:
- geyser;
- etc.
Design of a pumping station for a private house
As a rule, a pumping station is a combination of several separate mechanisms combined into one powerful water pumping apparatus. Each of the elements of the device has a very important task:
- Pump. The workhorse of the station. It pumps water directly from the source to the reservoir.
- Hydraulic accumulator. It is presented in the form of a hydropneumatic tank with a volume of 18 to 100 liters.
- Pressure switch. It controls the station.
- Check valve. Prevents fluid from flowing back to the source.
- Pressure gauge. Allows monitoring of pressure readings in the system.
- Connecting hoses and branch pipes.
Advice. The filtration system installed in front of the pumping station will not only provide users with purified water, but also extend the life of the plumbing system by removing hardness salts, organic compounds and suspended solids from the liquid.
What to be guided by when choosing a water pumping station
The first thing you need to pay attention to when buying a station is the power of the pump. The pressure of water in the system and its consumption depend on this indicator. The water supply parameter should be close to the maximum volume of consumption by all points of water intake. As a rule, this indicator is rather roughly averaged and all models are adapted to a nominal flow rate of 1.5-9 m3/h.

The pressure indicator is also entered into the table of characteristics of the station separately. In the passport, it is indicated as the distance to which the pump supplies water. But in fact, this parameter means the pressure that the station is capable of creating. So, the specified pressure of 40 m, shows that the pump will create a pressure of 4 atmospheres under ideal conditions. Since during operation there are some pressure losses on the pipeline layout, as well as the rise of water to a certain height, this figure will be much lower.
Important! Not always a powerful device justifies the money invested in it. As a rule, the productivity of such a system will exceed the filling of the well. In order to avoid this, it is necessary to take into account the parameters of the well. The shorter the distance to the source of water intake and the higher the level of occurrence of the water resource, the less power the purchased device should have.
Also, when choosing a water pumping station, it is necessary to take into account the autonomy of the unit. This will be needed by users living in areas with problems in the power supply. To ensure uninterrupted operation of the pump, you can additionally install a generator or solar battery on the site.
Types of pumps
Waterworks differ from each other in the types of pumping unit. This is the main part of the system, doing all the main work. That is why the emphasis must be placed precisely on the choice of a pump for a water supply station of a private house.
Surface pumps also differ in the type of ejector device. Designs are found with a built-in and remote device.
- Models with built-in ejector use when the occurrence of water is not more than 7 meters. Such pumps can lift water with a high concentration of mineral salts, gases and particles up to 2 mm in size. Capable of creating a lot of pressure. Water intake is carried out using a reinforced hose, the end of which is immersed in the source. As a rule, this type of pump is equipped with a coarse filter, which prevents sand and other large contaminants from entering the casing.
Centrifugal surface pump with integrated ejector
- Pumps with remote ejector are capable of pumping water from a depth of up to 40 m. In this case, the diameter of the well should not be less than 100 mm. A prerequisite for the installation of such a device is the additional installation of a filtration system. Such models are installed in the case when the water source is located at a distance from the pumping station.
Self-priming pump with remote ejector
The durability, noiselessness and stability of the plumbing system depends on the material from which the product body is made:
- stainless steel - increases the cost of the product, improves the aesthetic appearance of the station, does not affect the quality of the pumped liquid, but does not have noise insulation;
- cast iron - a prerequisite is the application of an anti-corrosion layer, pleases with a good level of sound insulation;
- plastic - almost silent, the possibility of corrosion and the presence of rust in the water is excluded.
hydropneumatic tank
Equipping water pumping stations with an accumulation tank will make the system autonomous in case of a sharp drop in the water level in the source. This is achieved by accumulating the nominal amount of water resource indicated in the documents accompanying the product. In addition, it acts as a pressure regulator in the plumbing system.
Hydraulic accumulators
The volume of the expansion tank directly depends on the consumption of the resource. Therefore, the greater the number of simultaneously active draw-off points, the greater the required tank volume. The most common models of stations are equipped with hydropneumatic tanks up to 50 liters. The maximum volume is 100 l.
Advice. If only 1 person lives in a house or in a country house, then a tank with a volume of 18-21 liters will suffice.
Electronic control - additional protection of the pumping station
To increase the life of the water station, it is equipped with an electronic control unit. The main functions that lie on it are protective.
The disadvantage of pumping stations equipped with electronic control is their increased cost. This is what turns many buyers off.
Rules for installing a water pumping station for a private house
The main thing when installing a pumping station on a site is the choice of a place for its placement. Here it is necessary to take into account all the basic requirements:
- the distance to the source of water intake must correspond to the characteristics specified in the passport;
- the device must be installed in a heated room if operation is planned in the winter;
- to avoid the appearance of condensate caused by the temperature difference between the environment and the pumped liquid, it is imperative to choose a well-ventilated room;
- soundproofing the walls of the room will help maintain the level of comfort in the house.

To dampen the vibration of the pump, the station is installed on shock-absorbing rubberized cushions or a rug. It is also important to take care of the grounding of the installation operating from the mains. This will ensure the safety of the interaction of the system with households.
In the absence of tightness of the nozzles of the station, pressure is lost. Therefore, in case of any deviations in the operation of the system, it is imperative to inspect all connections in the device.
Timely maintenance of the system will help extend the operation of the water pumping station. Regular inspection at the time of damage or blockages will save you from additional expenses for repairs and the purchase of new equipment.
