Einhell domestic waterworks GC-WW 1250 NN (1200 W, max. 5 bar, 5000 L/h flow rate, max. 50 m delivery height, maintenance-free motor, water drain screw, 20 L stainless steel pressure tank)

With this domestic water system from Einhell, users are particularly impressed by the combination of high performance and a comparatively low price. The pump should work reliably, but some reviewers on Amazon state that the domestic waterworks is only suitable for service water, not drinking water. This is said to be in the manufacturer's manual. Another small point of criticism is the volume. However, by placing the pump outside, i.e. where it does not disturb, this little problem can be easily solved.

Purchase Criteria
material
Domestic waterworks are made of either plastic or stainless steel. Although plastic models are often relatively robust and durable, they do not come close to the quality of the stainless steel versions. If in doubt, you should opt for a steel domestic waterworks, even if the price is slightly higher due to the better material. Aside from the functional advantages, stainless steel also looks more elegant in most cases.
power
You do not necessarily have to buy the domestic waterworks with the highest output (in watts). It is only important that the value corresponds to your project, i.e. that it does justice to it. For example, a pump with 500 watts is sufficient for a water system with only one consumer. On the other hand, 1,000+ watts are essential if you want to draw water from two or more water points at the same time. For three consumers or more, we recommend a domestic waterworks with an output of at least 1,300 watts.
flow rate
The flow rate indicates how much water the domestic waterworks can transport per hour. The more water you need, the higher the value should be. For your orientation: If you want to operate more than three lawn sprinklers (€26.95) via the domestic waterworks to water the garden, a flow rate of at least 4,000 liters per hour is required.
discharge pressure
The delivery pressure the domestic waterworks should have also depends on how many "consumers" you want to connect to the pump. Example: If it is only a matter of watering the lawn with two to three lawn sprinklers, 4 bar is usually perfectly fine. With more than three sprinklers, however, it is better to use a domestic waterworks that can build up a pressure of at least 5 bar.
head
The required head depends primarily on the area in which the domestic waterworks is to be used. With 40 to 50 meters you should always be right.
tips
It usually has to be 50 meters if you place the pump in the basement.
suction lift
Depending on the size of the well or cistern from which you want to transport the water, a certain suction height is required. While domestic waterworks with a suction height of seven meters are usually sufficient for simple rainwater storage tanks, you often have to rely on a suction height of eight to nine meters for groundwater suction.
important functions
self-priming: If possible, choose a self-priming domestic water system in order to save yourself the trouble of having to prime the pump before commissioning, which is often felt to be a nuisance.
dry run protection: Unfortunately, this essential feature is not yet standard for domestic waterworks. Dry-running protection prevents the motor from overheating when the pump is running dry. If you plan to connect the domestic waterworks to a cistern or rain barrel, you should buy a model with dry-running protection.
our recommendation
Gardena domestic waterworks Comfort 4000/5 eco: domestic water pump with dry-running protection, non-return valve, 3 connections, motor power 850W, flow rate 3500 l/h (1754-20)
224.08 EUR To the productpre-filter: If you want to transport rainwater or other potentially impure water with the pump, you need a version with a pre-filter. On the other hand, for pumping well or ground water, you can also use a domestic waterworks without a pre-filter.
frequently asked Questions
What is a domestic waterworks?
A domestic waterworks is a private water supply system. Such a device is used to transport service and/or drinking water - for example from a rain barrel or from a well. Each domestic waterworks consists of a maximum of four parts:
- Pump (usually a single or multi-stage centrifugal pump)
- manometer
- Safety valve (the non-return valve prevents water from flowing out of the pressure pipe when the domestic waterworks pump is switched off)
- Pressure tank (commonly diaphragm pressure tank or hydrophore; it ensures that the pump does not have to restart every time water is drawn)
How does a domestic waterworks work?
In a nutshell: The respective domestic waterworks sucks the water from the source (e.g. the well or the rain barrel) and then pumps it under high pressure through hoses - to the final destination, e.g. the lawn sprinkler or the washing machine, depending on what you use your pump for use exactly.

The domestic waterworks does not build up enough pressure. Why is it?
There can be various reasons why the pump builds up too little pressure. Here is an overview of the most common errors:
- incorrectly mounted or loose impeller
- defective seal(s)
- broken check valve
- Pressure hull/diaphragm no longer works properly
- Pump draws air
tips
If your domestic waterworks is obviously defective, you should no longer operate it, but first have it checked by a specialist and repaired if necessary. We recommend sourcing replacement parts from the pump manufacturer to avoid creating unnecessary compatibility issues.
equipment
water hoses
You need water hoses as connecting elements between the domestic waterworks, the water source and the final “receiver” of the water. Always ensure that the diameters of the connections match. In addition, the hoses must be able to withstand high pressure and generally be of high quality. It is always good to give preference to hoses from well-known manufacturers.
