The water pressure at my house seems quite high and with my bezzera commercial I have a resting pressure on the pump/line gauge of 7 bars, which seems a bit high.
I noticed when the washing machine uses water this will drop to about 5 bars and may swing quite high afterwards. It always returns to seven after the bezzeras pump kicks in. When coffee is extracted the gauge hits about 8 for a few seconds while the preinfusion pressure builds up to about 9 bars.
Should I install a pressure limiting valve for the machine? If so what pressure or what kind?
