Question about Rheem 81VP6S/430126 Water Heater
When I leave on vacation I turn off my hot water heater. When I return and turn the breaker back on the hot water overflow pipe dismisses water for quite awhile. I just returned and the same thing occured...it does not seem to be slowing down this time. If I turn off the water supply to the tank the water stops running out.

Do you have an expansion tank tank in the line leading into water heater? If not what is happening is that the water is no longer allowed to go back into the city supply. You said that you had turned it off while you left so the water heats up and has no place to go so the preasure/ temperature P/T valve opens and lets out the excess water from the expanded supply (heater water) that has no where else to go. It used to be that the extra expanded water just backed up into the supply pipe and back into the main. That is no longer possible in most places by the National Plumbing code. The answer may be to install the expansion tank into the incoming line. You can see then now at all hardware stores where water heaters are sold.
