I installed a new 50 gal water heater in my house about 2 years ago. A couple months ago I noticed that the pressure relief tube was dripping about a cup of water a day. I replaced the relief valve and still have the same drip. The temp is measured at 120 degrees. I purchased a pressure gauge today and read 65psi for the house. At the bottom of the hot water tank it goes off the scale at over 100 PSI. So I assume I have a pressure problem.
What I find strange is that I do not have a check valve or regulator on the incoming line, so I don't really understand why this would have changed a couple months ago.
I guess the solution is to install an expansion tank at the cold water line. Does 100 PSI on the tank sound out of line? Thoughts?
Thanks,
Erik
