Water pumps for home plumbing: tips on choosing, installing, reviews
In order to equip an autonomous water supply system, it is necessary to dig a well or drill a well, but this is not enough. It will also be necessary to take care that the water is supplied to the surface, and then it goes to the irrigation or water supply system. The conveyor can be a water pump for home plumbing. However, before purchasing such equipment, it is necessary to select the optimal characteristics of the model, the parameters of which coincide with the characteristics of the well or well.
What typical well pump to choose
If you need to equip the home water supply from a well or a well, then you can use one of the types of equipment, among them pumps of the following type:
The submersible pump must be located behind the ten-meter mark.As for ordinary pumps, they are installed in shallow wells, their mine should not be dredged into the soil for more than 10 m. But the surface pumps serve shallow mines, but are above the tip.
The above varieties include centrifugal and vortex models, of which the assortment of submersible, deep and surface aggregates consists. The equipment may belong to the automatic segment or be controlled manually. This suggests that the range of the described equipment is quite diverse, so in search of the optimal solution, it is necessary to explore all the aspects and design solutions of the model that may affect the belonging of the device to one or another variety.
Which pump to choose - surface or submersible
Water pumps for home plumbing, as mentioned above, can be submersible or surface. The latter are installed at the top or in the basement of the house. Such units supply water from a source by means of a pipe immersed in a well shaft. This pipe must be filled with water, because the dry surface pump does not work.Such a unit should be chosen for several reasons, among them it is necessary to single out the ease of maintenance and ease of installation.
The suction pipe can simply be lowered into the well and turn on the device, pre-filling the working chamber with water. In this case, the unit will begin to pump fluid. As practice shows, the ground-based apparatus is much easier to disassemble than the submersible counterpart. However, such a unit has its weaknesses, which are expressed in the risk of overheating, loud noise and insufficient performance.
Any pump makes noise, not only superficial, but we only hear the last one. The situation is similar with overheating. In the case of an immersion model, cooling takes place with the help of water, whereas for the surface model, it is cooled with a fan. Insufficient performance is also a consequence of low power. If the last parameter is impressive, then the performance will be high.
When to choose a submersible pump
If you still can not decide which water pump for home plumbing to choose, then you can pay attention to the submersible models, which are deep and ordinary.Some options raise water even from 30-meter mines.
Such units have strengths that are expressed in high performance, the ability to serve deep-water sources, no problems with cooling, etc. In addition, the submersible pump does not freeze even in the most severe cold. But such equipment has its drawbacks, which consist in the complexity of the repair. After all, the device will have to lift to the surface, and for this the entire system is dismantled. Submersible equipment options are often exposed to corrosion, in addition, they can drown after a break in the mounting cable.
Which pump to choose - vibration or centrifugal
Considering water pumps for home plumbing, you will come across vibrational and centrifugal models. Among the strengths of the latter version of the device should be allocated high performance, which is limited only by the engine power. Such a pump can pump out a lot of water, and its capacity is limited to hundreds of liters per minute. The fluid rises from a well of arbitrarily impressive depth.Power is limited only by the tendency to overheat the engine and the size of the body.
Before making a purchase, you must also pay attention to the sensitivity of the device to the degree of contamination of water. Vibrating pumps also have strengths, which consist in the ability to pump water with a large volume of sand. However, such a unit can pump out liquid with only 30 m maximum, whereas the capacity is measured in tens of liters per minute. Another disadvantage of the vibration pump is the tendency to silt the source being served. This is due to the fact that the vibration emanating from the pump provokes the destruction of the soil surrounding the well. This effect cannot be avoided even with the help of the most high-tech filters.
Which pump to choose - manual or automatic
The well pump can also be automatic. This option is more expensive, but it works longer, because it is controlled by sensors of overheating, fluid level and dry running.
As for the hand pump, it can only be turned on or off. Taking into account the specifics of using a home system, automatic equipment will be suitable,because its work can be synchronized with the sensor data, whereas the hand pump can only be used for watering.
Features of choice based on consumer feedback: "Bison ZNVP-300-25"
When choosing a pump for a well, you should also pay attention to consumer reviews. For example, the model that was mentioned above is a submersible vibration pump serving domestic water mains. According to consumers, with the help of such a device it is possible to raise water from a 5-meter well.
Capacity reaches 1400 liters per hour, and the pressure is 55 m. Such a unit, as emphasized by buyers, is suitable for a shallow well, but the vibratory nature can provoke siltation. Therefore, the unit can only be used from time to time, which, for example, concerns the irrigation system. The cost of the model, according to consumers, is not so high and amounts to 2,000 rubles.
Reviews of the pump "Caliber NVT-210/16"
Considering water pumps for home plumbing, consumers are primarily interested in prices. For example, you can buy the “Caliber NVT-210/16” at an even lower price than the above option. The cost of this device is 1100-1800 rubles.This submersible vibratory pump pushes water to the surface from a well, the depth of which reaches 10 m.
The pressure capacity of this option, according to customers, is quite impressive for a model and reaches 40 m. This pump has many positive features, among them, as buyers note, low cost and low electricity consumption, which is 210 watts, which is true for a regular chandelier . All these factors indicate that the device can be called ideal for the water supply of the cottage.
Water supply scheme
If you wondered how to connect the pump to the water supply, you should know what the layout of such a system looks like. For example, a serial connection is suitable only for a small house with a small number of consumers. But for full houses and cottages with permanent residence, such a scheme is not suitable. It consists of the following: water flows through the pipeline, and a tee is installed near the water consumer. If you use several consumers at the same time, then at the most remote one there will be a low pressure.
In contrast, you can put the collector connection, which is expressed in the lead pipe from a common collector to consumers.This allows almost the same pressure at each point. However, some losses will still be, problems with pressure associated with the distance from the pumping station, but much less than in the above situation.
Having chosen such a home plumbing scheme, you will encounter an increase in the cost of the system. This will be expressed in more pipes, but it is worth it. Thus, the scheme consists of some elements, among them:
- source of water intake;
- pumping station;
- tee with shut-off valve;
- water pipe;
- cold water pipe;
- pipe for hot water.
Features of the installation of the pump
Before you choose a pump for the water supply system in a private house and connect it, you need to select the equipment taking into account the performance of the well. The capacity of the unit will affect the speed of filling the tank, but when choosing a device it is better to take into account the mark of maximum water flow. Together with the electric cable and the pipe, the submersible pump is immersed in the well; for this, it must be hung on a galvanized cable using a winch. It is located inside the caisson.
In order for the system to maintain the required pressure and not to pump water back into the well, a check valve should be located above the pump. After the installation of the pumping station for home plumbing is complete, it is necessary to check the internal wiring and also to connect the equipment to the control panel.
As for the surface pumps, they are installed in the caisson, which is an underground well above the wellhead. There are alternative solutions when the suction pipe is pulled into the basement where the surface unit is installed. The external plumbing pressure line must be connected to the basement or to the technical area.
The accumulator will maintain constant pressure in the system and provide water intake points without delay in transport.
The pump and the accumulator will operate in automatic mode. This indicates that the unit will turn on only when the pressure in the battery drops. Its shutdown is carried out after increasing the pressure in the accumulator to the desired value.The control unit, which turns the pump on and off, is responsible for this interaction.
