The issue of water supply to the dacha is one of the main tasks of providing home comforts. The pumping station for dacha is the main element for supplying water from the well to the interior of the room.
The most demanded unit for water supply on a private plot is a pumping station for cottages. It guarantees the uninterrupted supply of water from the well or well to the house. The mechanism and arrangement of the station are not complicated.
A complete water supply system consists of the following structural elements:
- pump (surface or well);
- expansion tank for water;
- relay-controller (controls the operation of the pumping station);
- a pressure gauge (used to measure the pressure inside the expansion tank);
- check valve (prevents reverse water flow from the room);
- connecting hose.
The main parameters when choosing a pumping station are its technical characteristics:
- The ability to supply water from a source to a certain distance,
- height of water intake,
- volume of storage capacity,
To date, there is a large range of choice of devices to ensure dacha water supply. Each station has these or other advantages, differing in its cost and quality indicators.
When choosing a station, take into account the distance from the source to the house. The smaller it is, the less power a pump station needs. Also, the depth of occurrence of water masses in the well or in the well plays an important role here.
Choosing the most powerful station is not always justified because its productivity can be much greater than the well itself can provide. Also, do not buy the most expensive device. You need to find the best option, in accordance with the technical parameters and performance for a particular case.
Stable supply of water to the house for domestic purposes, can provide a pump capacity of about 3000-6000 l / h, and for cottage needs this figure is 600-1000 l / h. The volume of the expansion tank must contain at least 25 liters.
To ensure the supply of water to the house from the source, up to 8 meters deep, it is enough to power the station from, to, kW / h. If the depth of the source is more than 8 m, then it is necessary to use a downhole pump in tandem with the pumping station, the indices of which are equal, kW / h.
Submersible well pump has a cylindrical shape and a metal, stainless housing. It consists of a water supply device (screw or centrifugal), a compressor unit and a water intake compartment with a protective mesh. At the top of the pump there is an outlet to which a check valve and a water supply hose are connected.
Each summer resident, having information about all the necessary parameters of the suburban area, can freely calculate the required unit and make a choice of pumping stations for cottages.
Overview of pumping stations for holiday homes
After determining the type and type of the water supply system, it is necessary to review the pumping stations for country houses.
There are manufacturers who constantly use innovative approaches to improve the quality of their products. It should be noted their reliability and a large selection of models for water consumption for recreational purposes:
Pump station CAM 40-22 Marina
The model is equipped with a surface pump, which has a built-in ejector. The principle of water supply is carried out through an elastic tube, or reinforced, a strong water pipe of large diameter (usually 25mm or 32mm). The end of the hose or tube is immersed in water. It is equipped with a non-return valve. On the pipe near the pump, some summer residents are installing a filter, which prevents the entry of heavy substances into the inner water pipe.
The first start-up of the station must be carried out in accordance with the recommendations in the manual. Before running, through a special hole with a plastic stopper, water is poured. It must fill the space between the pump check valve and the compressor itself.
The most popular brands that use the technology of remote ejector:
- Wilo-Jet HWJ,
- Grundfos Hydrojet,
These pumps are designed to ensure the pressure of water from wells, the water mirror of which varies from 9 to 45 m. The connecting elements of such devices are two pipes.
ESPA TECNOPRES electron
This pumping station is electronically controlled, which provides security and has additional functions:
- protection from starting the pump without sufficient water level in the source;
- prevention of frequent starts;
- adjustment of start and control of a smooth set of engine speed. Due to this system, the sharp head of water is completely excluded, at which a zone of sudden high pressure (hydrostatic shock) can be created;
- energy saving;
The only drawback is the cost. Not every dacha owner can afford to buy such a pumping station.
Basic rules for connecting pumping stations
The location of the water source is the main predetermination of the method of installation of the pumping station. If it is near your home, you can install a small station indoors. If the pump produces too loud sounds during operation, then the expansion tank should be placed indoors and the pump placed in the well. For the winter, the opening of the well needs to be insulated.
It is also possible to connect the pumping station to the well via a special excavated pit with a hatch near the source. In this case, the pit should be insulated, especially in the winter season.
The optimal option for giving, in the case of placing the source at a distance of about 20 m from the house, will be the use of a deep pump. According to the rules for connecting pumping stations, this scheme involves laying pipes in the ground at a depth of at least 80 cm. The pipe must be laid on a sand pillow, so that in case of land subsidence, the pipe is not damaged. The very same tube should be worn in a heater.
The power cable seals into the pump, therefore the leakage of electricity is completely excluded. The other end of the wire is connected to the automation of the surge tank.
The expansion tank is best installed in a room that is heated in winter - a bathroom or kitchen. The tank does not create noise and has an aesthetic appearance, so it fits into any interior. The inlet pipe is connected to the expansion tank, and the other part of the pipe is tightly connected to the pump in the well.
Inside the room, the water supply system is plugged into the outlet, the pump is activated and water is pumped into the system. The pump operates automatically.
Having such a system at the dacha, the issue of comforts in the house is completely solved. An autonomous water supply system is more a means of comfort than luxury. Following the recommendations of experts, you can easily install such a system, even with their own hands.
