Found tub and shower valve was constantly passing water. Found pressure at a 120 psi. Explained to homeowner that we could replace parts, but the issue might come back quickly due to the pressure problem. discussed options with the homeowner. We decided to replace the pressure regulator to get the pressure back to a safe level first. gave price and homeowner agreed to PRV replacement replaced the pressure regulator tested new pressure at 70 found the drip at the tub had stopped at this time when the pressure issue was addressed. tested no leaks or failures at time of service.
