Our county water pressure routinely runs 100-110psi and I have recorded surges as high as 120. Calls to the utility dept. result in a service crew coming out throwing a leaky pressure gauge on a hose bib and telling me it is only 95psi which is below the 120psi maximum which would result in them providing me a free pressure regulator for my main, I would be responsible for the labor expense. Recently I had to install a new water heater and the instructions clearly said do not install if pressure exceeded 90psi. Monday I was talking to a neighbor and he said their bathroom flooded when the WC hose blew off and I had an icemaker input valve randomly fail flooding and damaging my ceramic tile floor in the kitchen. This time I have been persistent and finally got through to a manager that understood I wanted them to adjust the pressure for the area not make me pay to "fix" their problem at my house. Still waiting for a reply but everyone I have talked to seems to be hanging onto the policy of 120psi is the maximum allowable pressure is this reasonable? I found some county engineering specs online and they only address the minimum allowable pressure not the max. From my years of experience of DIY projects I believe 55-60psi is the recommended pressure for residential houses so I was shocked to here them tell me anything below 120psi was good to go.
