Here's my situation:
The pressure relief valve on the water heater is weeping (6 years old). I put a Y adapter on the garden hose bib so I can have a pressure gauge with a lazy hand one one leg and let water out of the the other.
Lazy hand said 150 PSI. If I run water, pressure returns to 80, then climbs.
Today with just me here, I checked the thermal expansion tank. It's shot. Air side was full of water and bench testing shows it won't hold pressure.
Turned the water heater off at the breaker to eliminate thermal expansion. No change it behavior at the gauge.
I got the regulator set lower, now at 40 psi. Gauge hovers there for a second and starts climbing. Goes over 100 within 5 minutes.
I think my regulator is shot. What do you guys think?

A new regulator and expansion tank and we're holding steady at 45 PSI. Mrs. West is unhappy with the reduction in pressure, she had become spoiled with street pressure. (Or is that spoiled further?) Anyway, I may have to crank it up a few pounds. Thanks for the help!

When I install them, I DO crank them up to 75-80 psi.
