Setting the pressure correctly in a domestic waterworks is crucial for the delivery performance and safety of the device. We'll show you how to do it here.
Minimal Print
The minimum pressure or minimum pressure is the so-called switch-on pressure. This determines when the system switches on. It should be between 1 and 2 bar. 1.5 bar is often ideal. However, this is an estimated value that must be varied depending on the system and the water column.
However, it should not be less than 1 bar. Because the system consists of two chambers and an air-filled membrane, which can be damaged by excess or negative pressure.
Maximum pressure
The maximum pressure is also known as the differential pressure. Once this point is reached, the system switches off. The difference between the minimum pressure and the maximum pressure is crucial for the delivery performance.
The greater the difference, the greater the delivery rate. If the water column is very high, the performance must also be correspondingly high. In general, the pressure should be between 3 and 4 bar. With some domestic water systems, the maximum pressure can also be increased to up to 5 bar.
Height of the water column
In order to build up the appropriate pressure, the height of the water column must be taken into account. It is important to take these into account when making your purchase decision. Pumps for water columns up to a height of eight meters can be purchased from a hardware store or other specialist retailer.
Even particularly powerful domestic waterworks are not designed for a delivery depth of more than ten meters. Even the highest pressure setting cannot solve this problem. In these cases, other solutions are available.
In general:
Select domestic waterworks to suit the height of the water column.
Diameter of the pipe
The diameter of the pipe also plays a crucial role. The larger the diameter or circumference of the pipe, the higher the pressure must be set.
Again, it is important to follow the manufacturer's instructions. Under no circumstances should the minimum pressure be undercut. This can cause various problems. These are:
- continuous running of the pump
- increased ongoing costs
- missing suction
- insufficient amount of water
- Waste of energy
Pump efficiency
The efficiency of the domestic waterworks should be as high as possible. Because this results in various advantages. Below:
- the pump runs for a shorter time
- Energy can be saved
- Noises caused by the running of the waterworks are shorter and often quieter
- larger delivery depths are possible
- Price differences are often small
Setting the pressure – instructions
Setting the pressure on a domestic waterworks is comparatively easy and can be done in just a few steps. The following step-by-step instructions will help:
- The cover on the pressure switch must be removed.
- There are at least two and at most three adjusting screws behind the cover. The largest screw is normally used to regulate the minimum pressure. The maximum pressure can be adjusted using the small screw.
- By turning left or right, the pressure can be reduced or increased. Please pay attention to the pressure gauge display.
Tip:
The manufacturer's information must always be observed, as the different types and models of domestic water systems can differ significantly from one another. In order to avoid errors and damage, the details must be taken into account.
