Water pumps for home plumbing: a review of popular models
Water pumps for home plumbing are necessary to ensure uninterrupted circulation of fluid and the required level of pressure in the water supply system of the entire site. Therefore, the choice of this equipment should be approached with all due attention.
So let's take a look at its varieties and main characteristics.

Kinds
So, let's proceed to the introduction:
Submersible

Submersible type machines can be vortex, centrifugal and worm. Due to their high practicality, centrifugal machines are the most common, we will consider them:

Designation in the figure | Title |
one | Pump part |
2 | Electric motor |
3 | Power cable |
four | Valve |
five | Nameplate |
6 | Protective cover |
7 | Protective mesh |
eight | Mesh or drain plug |
These models are immersed directly at the bottom of the well itself, from where they deliver fluid to the system.
Advantages:
- Affordable price.
- High level of power and performance. These models are ideal for servicing artesian wells.
- Small diameter, which allows to do by drilling a narrow well.
- Ease of operation with their own hands.
- The long operational term thanks to lack of the rubbing elements.
The disadvantage is the difficulty of repair work, which is associated with the need to lift the device from a great depth.
Connection:
- We connect the power cable, hose and steel cable to the device.
Tip: it is recommended to connect the connected elements in one tape with building tape. This simplifies the process of immersion and the subsequent rise.
- Immerse to the bottom of the well.
- Fix the cable on the tip.
Semi submersible

These pumps are an intermediate between submersible and surface models. They are inferior in the aggregate of technical characteristics and cannot perform specialized tasks, but they have several advantages that make them more convenient when working with small, wide wells.
Namely:
- Easy maintenance. After all, this equipment does not require complete immersion.
- No need for complete sealing.
The connection looks almost the same as in the previous version, only it is required not to wet the upper part of the device.
Pumping station

The main tangible difference between this option is the presence of a hydroaccumulator, which allows to accumulate water for its further transportation to the points of water intake. In most cases, in addition to other naos, you will have to install such a unit anyway. This equipment is mounted in a specially equipped caisson or basement.

Designation in the figure | Title |
one | Management station |
2 | Network cable with plug |
3 | Network cable with socket |
four | Circuit breaker |
five | Power outlet |
6 | Water source |
7 | Input strainer |
eight | Check valve |
9 | Suction pipe |
ten | Surface pump |
eleven | Pump cable with plug |
12 | Injection pipe |
13 | Nipple |
14 | Cross |
15 | Accumulator |
sixteen | Nipple transition |
17 | Flexible eyeliner |
18 | Pipeline to water intake points |
Benefits:
- Full Automation. Due to the presence of automation control over the operation of the station is not needed, which greatly simplifies its operation.
- Ensuring the required level of pressure in the water supply system, which is required for the operation of many plumbing fixtures.
- Elimination of water hammer. Due to the peculiarities of its structure, they ensure an even flow of liquid, which increases the operational life of the entire water supply system.
- Ability to work without electricity. In the event of an accident at a power plant or wire breakage, the water will continue to flow for some time until the hydroaccumulator is empty.
- Increase the operating period of the pump, as its number of inclusions and shutdowns is reduced.
- Simple instructions for connecting to the water system.

Tip: it is recommended to warm the room in which the described device will be located in order to prevent water from freezing in the storage tank during the winter period.
Disadvantages:
- Relatively high cost. Although during operation, the initial costs quickly pay for themselves.
- Limit the depth of water lift, which is usually 10 m.
Connection:
- We choose a reliable stable place and install an aggregate on it.
- We connect to power.
- We lower the suction hose into the well.
Circulating

This device does not serve to raise water from the depth, but provides the necessary pressure in the plumbing system.
Due to this, it has a slightly wider range of applications:
- In combination with water lifting devices unable to create the required pressure level.
- In heating systems, especially it concerns water heat-insulated floors.

2 | Threaded plug |
3 | Technical Label |
four | Body part of the stator |
five | Bolts |
6 | O-ring seal |
7 | Outer bearing shell |
eight | Shaft |
9 | Bearing stop |
ten | Bearing plate |
eleven | Stopper |
12 | Split Cone |
13 | Working wheel |
14 | Nut |
15 | Slot sealing |
sixteen | Pump body |
17 | Sensor connector |
nineteen | Splash ring |
Connection:
- Shut off the water supply in the circuit.
- Cut off part of the pipe.
- We mount the device in its place.
Tip: if you create a parallel branch for the circulation pump and equip it with shut-off valves, you can turn off the device at any time and perform maintenance without stopping the entire system.
Calculations
If you want the selected circulating equipment to perform its functions, then before purchasing it, it is necessary to calculate the device power required for your site using the following formula:
H = (Hone + H2 + H3) * 20%, where
- H - required pressure, measured in meters;
- Hone - the number of meters from the bottom of the well to its mirror;
- H2 - the number of meters from the borehole mirror to the exit from it;
- H3 - the capacity of the water-lifting pump specified in the instruction.
After receiving the desired value, you will know exactly how necessary to increase the pressure in the pipeline.
It is also useful to calculate the required performance of your water-lifting apparatus:
P = pone + p2 +p3 + ... + pn, Where
- Р - necessary productivity for providing all water intake points with water;
- R.n - the amount of fluid consumed by each point separately.
Conclusion
As you can see, several variants of pumping equipment are used for arranging the water supply system of a private house. Since the submersible is indispensable when lifting liquids from artesian wells, semi-submersible ones will be more appropriate when servicing wells, pumping stations will be an excellent and completely autonomous choice for sand wells, and circulating ones will be able to increase the missing pressure in the pipeline (see also the article We build water supply from a well into the house) .
In addition, do not forget about the need for preliminary calculations of the power indicators of future equipment.
