I have my pressure gauge hooked up to the drain faucet on the hot water heater. All day long it stays at @60 PSI, all evening it stays the same, at 11PM I go to bed and it is the same.
I check it in the morning and the red needle is sitting at 140 PSI and the current PSI needle is setting at 60.
Street PSI goes up at night, that I do know. My PRV was installed in the late 1980's and it is suspect. I also removed the expansion tank and it was never pumped up past the 40 PSI. So I pumped it up to @60. When I set the hot water heater up to as high as it goes there is no spike --- so I believe the expansion tank is working.
I did set the PRV back to 60. It was showing 80 psi.
I always thought a PRV is good for a long time but the water company tells me that we are in a high pressure area (needed to pump up the big hill) and that a PRV is only good for 10 years.
So am I looking at a new PRV.
