PRV is regulating too much!
Posted by Madonna on December 27, 2003 at 10:53:38:
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?
