We discovered that we were getting water leaking out of the pressure relief valve/pipe... about a cup per day.
I called in a plumber and they suggested that our pressure in the tank was really high. They changed a main feed from outside and also changed the pressure valve. This was fine for about 2 weeks. We are now seeing water coming out of the valve again.
What else should be checked or what can be suspect? The water heater is 9 years old... is it that I need a whole new one?
Any advice would be great! Scott
