I've got 2.2 bar where mains enters house and 1.8 bar at showerhead.
The shower spray is weak though. Its takes along time for my wife to wash and rinse her hair. The spray is more like rain than a mains pressure hot and cold shower.
Is 1.8 bar a reasonable pressure to give a powerful shower?
Is a 0.4 bar pressure drop between ground floor and first floor normal?
I've got mains pressure hot and cold water, so, I've been told, can't have a booster pump installed.
Assuming that 1.8 bar is good enough, any suggestions what is causing the 'soft' shower spray and if anything can be done about it?
Thanks in adavance.
