ATWOOD Water heater
Water heater spillage from pressure relief valve, emptied water tank. Is the pressure relief valve bad?:h
Forum Discussion
I suppose if the pump doesn't shut off at the proper pressure it could build up enough pressure to relieve out the t&p valve until the tank is empty! However IMHO the more likely possibility is that the t&p valve is bad. and its a quick and easy replacement. If the pressure switch is at fault it is a bit more involved unless you just replace the whole pump.
