Re: Water Heater Temp/pressure valve leak
The PRV will leak if the temp or pressure is exceeded.

Over heating can cause a pressure that exceeds normal operating conditions. NashuaTech's information was correct. Reducing the temp would be the first option to try. An expansion tank should not be needed if the WH is operated within its recommended settings.
You are right, Dodds did seem to throw a tantrum rather than just suppling information.
