In response to Re: PRV is regulating too much!
: We recently had to have the main water line to our house replaced. Afterwards the water pressure increased for a while but then went back to what we had before replacing the line. About two weeks ago it jumped up extremely high. I was concerned about this harming the house pipes so I called the plumber that installed the main line. I was told that our PRV probably went bad. They came out - we did not have a PRV so they installed one - $400.00 later. Now, the pressure is terrible. The plumber told us that we could adjust the PRV to regulate the water. We tried but there was no change. The plumber came out and adjusted the PRV as wide as it would go. Then he checked the PSI from the city main, which is 90 and the house PSI is 75. But, the pressure is considerable lower. Any suggestions?

The PRV is not regulating too much. 75 PSI is at the top end of permittable pressures.
I don't quite understand what you are saying. You say the house is 75 psi and the next sentence says the pressure is considerably lower? Where is it lower? How much lower? How do you know it is lower? Where did you check it? Is everything affected? Is this a volume problem? Did you clean all areators after the work? Has the screen in the PRV been checked to make sure it is not clogged? PSI is PSI.
