Pumps for water supply - an overview of the main options and
The plumbing pump is an important element of many systems, it is necessary when pumping water from a well or a well, installation of this type of equipment is also justified in cases when the pressure in the central water supply is too low. With the help of boosting pumps, it is possible to achieve a stable pressure in the system and to ensure the correct operation of heating devices, if any.
It is important to choose the best option that best suits your conditions.
Types of equipment
As noted above, there are several basic options that differ significantly from each other both in design and in the nature of their functions. The most popular and in demand are the following types:
| Centrifugal pumps | This type of equipment is also called boosting due to the nature of its functions. Its main purpose is to maintain a certain level of pressure in the system, it turns on only with a weak head, and does not work the rest of the time, this allows saving on energy resources. Also, the products are characterized by compact dimensions, which allows them to fit into any system. |
| Surface pumps | This option differs in a big variety - from small installations to powerful pump stations. The depth of water rise is about 8-10 meters (depending on the modification), while ensuring good performance. The pump automatically starts when the pressure in the system drops below the set value. |
| Submersible pumps for wells | This option is different in that it is located right in the working environment - water. A special float holds it on its surface, which can also function as a fluid sensor; if it does not, the equipment simply will not turn on. The option is great for country sites, because it is easy to connect, and if necessary, dismantling also takes a few minutes. |
| Well Submersible Pumps | This option is installed directly in the well at a great depth, therefore, the quality and durability of such products are increased, naturally, this increases the price. It is better to choose stainless steel modifications that are not afraid of impurities in the water, since in the well in any case there will be no absolutely pure water. |
Tip! When choosing, pay special attention to the manufacturer, since quality and durability largely depend on this. And do not chase for savings, as the cheapest options, as a rule, serve at times less than good-quality products.
Features of using some options
To ensure that the water supply is constant and stable, you must purchase a pump with the appropriate characteristics and properly install it. Usually there are two values in the marking, the first of which denotes the conditional passage of the pipe on which the equipment is placed, and the second reflects the pressure generated in the system (for example, 80 is 0.8 atmospheres, and 160 is 1.6).
Boost installations
Instructions for installing and using a pump designed to increase pressure are very simple, but you still need to know a few basic rules that we will consider in this chapter (see also the article Water Pumping Station: general information and practical recommendations).
Connection diagrams of a booster pump for water supply can be very different, it depends on the system features and the required performance:
- Small constructions are used for individual use, the products of the Grundfos brand have recommended themselves well; at a reasonable cost, the quality meets the highest standards.. Such option differ in small energy consumption and noiselessness of work.
- If the size of the room is large or the volume of water consumption is significant, then one pump can not cope, in this case, you can install two pieces of equipment. They will provide a significant increase in power and will work as a single system, while the load on the structure will decrease, which will have a beneficial effect on its durability.
- If you need to increase the pressure in a multi-storey building, you can do it in two ways - either install a separate pump in each apartment, or use a special hydrophore unit that is installed at the house entrance and has high power and performance. In addition, install one unit is much easier than dozens of individual products.
Surface pumps
Booster pump for water supply, located in a specially designated room in the house or in a separate building, differs from the above option:
- The design consists of a centrifugal pump and a special tank, due to which the pressure in the system is maintained.
- A check valve must be located on the suction line so that when pumping water does not leave the system.
- It is very important that all connections are tight, otherwise the pressure will constantly drop, and the pump will work much more than necessary, which leads to a significant waste of energy and increased wear of the equipment.
Note! When you first start, do not forget that the system must be filled with water, otherwise the equipment may overheat and fail.
Submersible equipment
This option is very easy to use:
- The pump is fixed on a special rope or just floats close to the surface on a special float.
- It is very important to secure the equipment properly, otherwise it will be quite difficult to remove it after a support break.
- When installing, focus on the electrical connection, it should be reliably protected from moisture.
- Borehole pumps must be resistant to impurities in the water, as sand will somehow get into the system, for the same reason it is necessary to install a cleaning filter.
- It is very important to choose equipment with an appropriate capacity in accordance with the volume of water consumption. This eliminates wear due to high loads and ensures a stable pressure in the system.

The video in this article will tell some more important nuances from the topic under consideration and help you choose a water pump for home plumbing. It is important to take into account all the nuances and not to miss a single significant detail, since any small thing influences the choice of a particular modification.
