I have a 125 psi pressure-only relief valve on my water heater cold water inlet, about 2 feet before the tank (in addition to the normal 150 psi T&P valve). The pressure-only valve has been leaking for several months, between a pint to a gallon a day. I replaced the valve, same thing. I suspect my service pressure is too high and is causing it to open intermittently. Service pressure was 80 psi when I moved in 5 years ago (inspector commented it is at the upper limit). My questions: What is upper limit on service pressure from the utility? If it is high, should I expect them to install a regulator? Or does the homeowner get stuck with it. I'm calling the utility KCWD90 to check this, they replaced the meters at my place and the neighbors a few months ago, I seemed to notice this leak about then.
Thanks for any advice,
Rob
