An optimal water pressure is necessary in every house connection. This ensures an adequate water flow even on higher floors. The ideal value is between 2 and 4 bar. However, the values ​​may vary depending on the size of the building. In larger residential complexes, the water pressure must be high enough so that it is at least 2 bar even on the top floor. On the other hand, if it is set too high, the water consumption increases.Sometimes this also causes damage to the pipe system, which is why most pipelines are approved up to a pressure of 16 bar. The following guide explains how to test the water pressure, what causes high pressure ratios and how to correct possible problems.

Test the water pressure

You will find the pressure regulator directly next to the house water connection. In a single-family house, the value should be 2 to 3 bar. Whoever lives in a rented apartment does not always have free access to all rooms in the building. However, you can check the water pressure in your home without going through complicated measuring procedures. All you need is a 10 liter water bucket and a stopwatch. Fill the bucket with water by turning the tap on fully. If this is completely filled within 30 seconds, the water pressure is around 4 to 5 bar. If, on the other hand, the process takes one minute, the pressure is around 2 bar.

What to do when the water pressure is high

As already mentioned, excessive domestic water pressure causes costs and damage. In this case the pressure regulator is set too high and you should reduce the water pressure on the regulator. Then test whether there is still an adequate jet of water on all fittings in the building. If you do not have access to the domestic water supply, it is best to notify your landlord, because as a tenant you are entitled to an adequate water flow in your apartment. Another way to remedy excessive pressure conditions are pressure reducing valves. These ensure that the pressure on the outlet side does not exceed a certain value, even if the inlet pressure varies.

Conclusion

If the water flow is insufficient or excessive, first look for the cause. The first point of contact in this case is the pressure regulator on the house water connection. Read off the value and, if necessary, vary the setting so that it is within the normal range between 2 and 4 bar. If you do not achieve any improvement with this measure, the problem lies elsewhere. Investigate where the water pressure deviates. Is only the shower affected, but not the sink? Gradually dismantle the system and remove calcification. If necessary, replace defective individual parts. Are all lines affected? There may be leaks in the pipe system. In that case you need to notify a plumber immediately.
