I have high water pressure. My supply side pressure coming from the meter is approx 160psi. I have a Watts 35B regulator and while the water is running it works flawlessly, I just replaced all the rubber parts from a rebuild kit. I have the running water pressure set at 60psi. That being said, on 3/4" copper pipe, as soon as I shut off the water, my water pressure quickly climbs to 110psi, and if left to sit long enough, will climb to match the supply side. To some degree i'm sure it could be thermal expansion from the water heater, but how fast it climbs immediately after turning off any fixture leads me to believe its just from the supply side. Is there a solution to this? Would 2 regulators ever be able to deal with it? Is an expansion tank necessary or would it even stop the problem? The house is only 6 years old, but I still worry about my pipes bursting from the high pressure. |

What they said.... Plus, 60psi seems a tad high, for your inside pressure. I'm only an electrician, but I've picked up a few tidbits along the way from guys on jobsites. Funny you said that number, I actually remember more than a couple plumbers back home in CT mentioning the water pressure was about 60 psi as well in the town we worked in and it causes them bunches of problems. Anyways, it sounds like your regulator has a small internal leak. Probably why it's "mostly" working, but slowly equalizing the pressure on the low side, to the high after a while. I'd replace it and see what happens. |

Regulators are default set at 50, I just bumped mine to 60 after I rebuilt it since I have a 2 story and want decent water pressure for showers upstairs. A new regulator is $95, I was hoping to not have to replace it, 5-6 years seems like a pretty damn early failure, the Watts 35b is rated to handle incoming pressure up to 400psi. |
