A domestic waterworks increases the water pressure in the water pipe and is used in the house, in the yard, and in the garden. Whether as a garden pump or as a self-priming pump: the house waterworks provide automatic water pressure in the line and supply the area with sufficient hot water from wells, cisterns, and rainwater barrels. For example, automatically increases in a pressure drop, the water pressure. In most cases, a domestic waterworks is used in rainwater systems or in conjunction with sprinklers.
Top 10 Domestic Waterworks
What is a domestic waterworks?
The domestic waterworks can be described as a self-priming garden pump or as a booster pump. The function has given the machine its name. Thus, the water pressure automatically increases in the water pipe, for example, irrigate or irrigate lawns, beds or gardens. In addition, domestic waterworks
- washing machines,
- Sink and
- Fill the toilets.
The pump works with an automatic water pressure acting on the pipes. Especially in piping systems where a permanent water pressure is required, the use of domestic water systems is recommended. These ensure that the water pressure increases with a possible pressure drop.
The purchase and selection of pumps are related to local requirements. You should know in advance exactly what you require from a device and for what purpose you use it. In the direct domestic water plant comparison on gmomf.org convince the traditional brands and the well-known label with a frictionless function, easy operation, and commissioning.
Why do I need a domestic waterworks?
With a domestic waterworks, you pressurize the pipes and hoses at home automatically. A comparison with a garden pump or with a rainwater system is helpful. It makes sense, for example, to switch the domestic waterworks between the water pipes, especially if you are particularly likely to low pressure.
Domestic waterworks or water boiler?
- HWW: Compressor and pump for automatic pressure regulation come together in the domestic waterworks. This provides an optimal basis for a functioning water supply in the garden and in the house. The complex domestic waterworks also allows the connection of several consumers.
- HWA: The domestic water machine is a pump with a flow switch, a flow switch and a flow switch. Depending on the water pressure, the pump can automatically switch the line with a flow switch. For example, if you close the tap, the pump will automatically shut off and protect itself from dry running. If you are looking for the right machine for garden irrigation or you would like to pump from cisterns and wells, then you are well advised with the HWA.
Buying guide domestic waterworks: What should be considered?
We distinguish three variants when buying and choosing the domestic waterworks.
- The pumps with a pressure drum and with a pressure switch,
- the devices with electric regulator and
- the domestic waterworks that use a frequency converter.
Basically, the local requirements decide on the purchase of domestic waterworks. For example, if you want to use a specific water buffer, it makes sense to buy a pressure switch and a pressure drum. The standard recommends a content of 20 liters, with deviations up and down. If only very little water is taken off, pressure switch and pressure would almost not activate. If the domestic waterworks is used with a fluctuating power supply, such as on boats and ships, this combination makes sense.
Compact domestic waterworks combine electrical regulators. The system activates as soon as the pressure drops. After that, the pump supplies you with water and pressure. The third variant is governed by the frequencies and variable speeds. These domestic waterworks can be switched on and off smoothly and are based on the desired speed. So you can provide the consumers with sufficient pressure or water. At best, set the respective variant via a clear LCD display. Often, domestic water heaters with frequency converters can save a lot of energy and resources, making them the ideal solution for home and garden.
In principle, you should trust your gut feeling and your eye when choosing a domestic waterworks. A complete construction of lightweight or low-grade plastic would make little sense because this material would not withstand the high loads and vibrations in the long term. For this reason, the leading domestic waterworks rely on a harmonious combination of high-quality raw materials, which were perfectly processed.
What does a domestic waterwork cost on average?
Quality has its price. This also applies to the purchase of a domestic waterworks. The cheapest pumps include the devices with pressure switch and pressure drum. Here the prices start at about 150 euros. Step by step it goes upwards with the electronic controllers from 200 euros up to the domestic waterworks, which operate frequency-controlled and only start at about 500 euros. We arrive at a price range of 150-1,200 euros.
How can I connect a domestic waterworks?
For the installation and the connection, you do not need a professional in every case. In most cases, even inexperienced do-it-yourselfers are perfectly well able to do the installation. Often we find two situations in which the purchase of a domestic water plant makes sense:
In the first scenario, there is already a line or pump at a source, such as a rainwater well or a lake. The domestic waterworks is the amplifier that you place between the pipes. Often it makes sense to install the waterworks near the water meter. Everything that comes after the pump then has a higher pressure. So it makes sense to place the pump at the earliest possible point of the line.
If you also use the house waterworks as a self-priming pump, it should be as close to the source as possible. For example, the water comes up from a rainwater well via a suction hose. At the same time, the domestic waterworks pressurize the pipe to channel the water.
Use domestic water supply at low pressure in the house and garden
Consumers often find that the water pressure in the house is too low, such as in the shower. Just when you open several faucets, the water pressure decreases. Here a domestic waterworks offers an ideal solution. Just switch it between the water pipe and install it in the house. Then it will react to the pressure drop and make sure that a consistently high amount runs out of the faucet.
How does a domestic waterworks work?
The structure tells us something about how it works. If you spend a few moments with the process, you will later buy the proper domestic waterworks. For example, there is a suction hose and a pressure connection on the pump. The domestic water supply supplies the pump with water via the intake hose.
- Connect this suction hose to the suction port when you bring the water from an external source.
- Hang the suction hose in the water. In many cases, it is extremely important that you keep the entire circuit airtight.
- As soon as some air enters the line, the pump can no longer work properly and exploit its full capacity.
- If it should happen that air gets into the pipes, it is necessary to vent the pipes and the hose.
Insert pressure vessel for the domestic waterworks
Often the manufacturers do without a pressure vessel in a domestic waterworks. A pressure vessel would prevent the water hammer of the pump. Now, most domestic waterworks in connection with the washing machine and the toilet are always under a slight leak. These are returned to the water reservoir in the sink. You can not recognize it with the naked eye. Nevertheless, a domestic waterworks constantly refill water. Only via a pressure vessel can you make this reserve usable.
What does the frequency converter do?
Using a frequency converter, the pump only makes the turns it really takes to transport the desired amount of water. So the pumps work energy-saving, which is reflected in lower energy costs. This increases the service life by automatically turning the revolutions downwards over the long term and without exposing the pump to unnecessary shocks. Especially since the waterworks protect themselves against dry running, which would have a disastrous damage to the entire system.
The right accessories for the domestic waterworks
|Filter :||For example, use rainwater, it does not correspond in quality and cleanliness to tap water. Here the use of filters and prefilters makes sense. These can be placed between the domestic waterworks and the intake hose and keep away finer or lighter substances.|
|Pre-filter:||The pre-filter is actually placed in front of the house waterworks to filter the water before it flows into the house waterworks. This is always recommended when you get water from a not completely clean source.|
|Special filters:||Special filters are available for fragrances, tastes, and chlorine. These filters are useful when pumping from natural sources to household appliances.|
|Connections:||Depending on which water pipe you connect to a domestic waterworks, you need adapters or ideally a complete connection set. It is equipped with the most common connections and simplifies installation.|
|Dry run protection:||In this case, the house waterwork cools with water itself. The pump should only run when it gets to the water. Otherwise, the risk of running dry increases. At the same time, the temperatures rise in the device, which then destroys it. The leading brands protect their domestic waterworks against this danger. If there is a dry run, the systems switch off automatically. For other domestic waterworks, it makes sense to additionally add a dry-running protection system.|
|hoses||Every domestic waterworks works only with a hose. It leads the water from the pump to the source or the target point. The hoses should withstand high pressure and be of good quality.|
House waterworks: Where is the check valve located?
For many pumps, the check valve is installed as standard. A check valve is a tool for the garden pump that you definitely need. The water flows through the intake hose from the pump to the outside to reach the destination point. Now we want to prevent this water from running back to the origin after switching off a pump. For this, we need a check valve. The valve opens only to one side. It lets the hot water flow up, but not back into the original container.
Insert check valve correctly
Actually, a domestic water system comes without a check valve. Once the hose runs empty, it may take a few minutes for you to pump new water from the cistern. For those who just want to blow up the lawn, a waiver of the check valve would not be recommended. Otherwise, the pump will take damage. If the house water system does not have a check valve, it should be mounted afterward.
Select a check valve with an integrated sieve. So dirt particles from the rain barrel cannot be transported. Sometimes there is the talk of a filter in the product description. Disconnect the garden pump from the mains before installation to avoid unpleasant incidents. Mount the check valve to the suction port. The necessary sealing is provided by hemp or assembly line. Take special care when sealing. Smallest air holes stand in the way of a perfect function.

How to vent a domestic waterworks
Most water pumps do not have to be vented today. Only the self-built or older domestic waterworks require in retrospect for a vent. It is not always possible to vent properly, especially if the wrong air was sucked in. It may be the foot valve is no longer tight. Maybe the sieve is clogged or the filter is no longer tight. Check if there is a leak anywhere from the inlet to the pump. First refill it completely. This is always the case when the domestic waterworks cannot draw in any more water on their own. To do this, fill the vent with water.
The modern pumps have a microswitch to measure the pressure. Attention: These switches can break quickly. If the pump mistakenly aspirates air, it accumulates on the front wheel and cavitation can occur. This refers to the formation and dissolution of vapor-filled cavities in liquids. Make sure that this condition is resolved as soon as possible. Otherwise, this can lead to a complete defect.
