Hello everyone,
a few details about the house:
Newly built in 2016, moved in September. Municipal water pressure according to the pressure reducer is 3.5 bar. Water softening system with 3/4" connection, Grohe Euphoria shower fittings.
My problem is that I have relatively low pressure in the showers and otherwise the flow rate is rather poor. The washing machine does not report any issues and I measured and got about 8 l/min in the showers and at the other fittings.
In the bathtub, however, it is already about 11 l/min.
In terms of the environment, it is of course great that less water flows automatically in my house, but it is not nice when instead of a powerful jet only a quiet dribbling comes out of the shower head. Unfortunately, there is no proper flow.
Now unfortunately I do not know what could be the cause. Could the flexible hoses at the water softening system play a role? As a test, I bypassed the system at the mixing valve but could not detect any difference.
Somewhere there is a problem, right, or are the 3.5 bar from the utility company simply not sufficient? Maybe the wrong hose sizes were used in general? Unfortunately, I do not know what has been installed, but normally the fittings have 3/8" connections and that is already small; I assume that everything before that is larger, right? Shouldn’t the flow speed automatically increase as the pipe gets narrower?
For your information, I have the same flow rate in the showers in the basement and upper floor. These are installed close to the municipal line (therefore only in one direction without circulation). I estimate the maximum length to be about 10 m.
The kitchen water is much further away (I think about 20 m), but the same rate of water comes out there as well.
I hope you can shed some light on this and provide me with a solution to increase the pressure on the shower.
Best regards
