: I am a 30yr old plumber living in Boston, Mass. We here have recently experienced a really cold spell and a lot of old water mains are being replaced and it seems to me that water pressure is rising in a lot of houses. This message is in regards to houses with larger water mains (ie: 1 1/4", 1 1/2"). I went into a house that the plumbing system was making a very loud moaning noise is the best way to describe it even if no faucets were being used or anything. This problem stumped me and 2 of my associates until I put a pressure guage on the potable water system and sure enough the pressure would hang right around 80psi wich is real high anyway then drop 10 psi to about 68-70 psi and rise again. While it was rising the moaning noise would occur and particulary at the kitchen - bathroom tees. I ended up solving the problem with a pressure reducing valve and putting at about 55-60 psi. I wanted to share this to see if anyone else in the area has seen this problem anywhere else?

The size of the water main has nothing to do with the pressure.
Did you also install an expansion tank?
