Our recommendations

The unanimous opinion of Amazon reviewers is “This Domestic waterworks von Gardena does what it should ”. The high quality of workmanship, which brings a long service life with it, is praised (some customers write that they have been using the pump for four years and still have no problems) and the pronounced one Pumping power. Installation should also be very effortless, even for laypeople who have never come into contact with a domestic waterworks before.

With this Einhell domestic waterworks, users are particularly impressed by the combination of high performance and 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 for drinking water. This is allegedly also so in the manufacturer's manual. Another small point of criticism is the volume. By placing the pump outside, i.e. in a place where it does not interfere, this problem can be easily remedied.

Güde's domestic waterworks are described by users as being very well made, easy to install and extremely functional. As for the basic features, this pump does absolutely solid.

Purchase criteria

material

Domestic waterworks are either made of plastic or stainless steel. Although plastic models are often relatively robust and durable, they cannot match 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 its functional advantages, stainless steel also looks more elegant in most cases.

power

You do not necessarily have to buy the house waterworks with the highest output (in watts). It is only important that the value corresponds to your project, i.e. it does justice to it. For example, a pump with 500 watts is sufficient for a water system with only one consumer. In contrast, 1,000+ watts are essential if you want to draw water from two or more water points at the same time. If you have three or more consumers, we recommend a domestic waterworks with an output of at least 1,300 watts.

Delivery rate

The delivery rate indicates how much water the domestic waterworks can transport per hour. The more water you need, the higher the value should be. For orientation: Would you like more than three via the domestic waterworks Lawn sprinkler(€ 27.99 at Amazon *) to water the garden, a delivery rate of at least 4,000 liters per hour is required.

Delivery 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 or three sprinklers, 4 bar is usually perfectly fine. If you have more than three sprinklers, it is better to use a domestic waterworks that can build up a pressure of at least 5 bar.

Delivery head

The required head depends primarily on the area in which the domestic waterworks is to be used. But with 40 to 50 meters you should always be right.

Suction lift

Depending on the size of the well or the cistern from which you want to convey the water, a certain suction height is required. While house waterworks with a suction height of seven meters are normally used for simple rainwater storage tanks are sufficient, they are often at a suction height of eight to nine meters for groundwater suction reliant.

important functions

Self priming: If possible, choose a self-priming domestic waterworks in order to avoid having to start up the pump, which is often a nuisance, before commissioning.

Dry run protection: Unfortunately, this essential feature is not yet standard in domestic waterworks. The dry run protection prevents the motor from heating up excessively when the pump is running dry. Plan to have the domestic waterworks with a cistern or one rain barrel To connect, you should buy a model with dry run protection.

Pre-filter: If you want to transport rainwater or other potentially impure water with the pump, you need a version with a prefilter. For pumping well or groundwater, however, you can also get by with a domestic waterworks without a pre-filter.
