|In response to Re: Leaking TP valve on new gas H2O heater|
: The old heater had the problem of a leaky TP valve for about the past year, BUT NOT prior to that. Is it normal to not need one (expansion tank) and then all of the sudden need one?
It can if something like a check valve has been added at the water meter. This is becoming more common as utilties add measures to prevent back-flow contamination. Disregard the water shutoff on the hot side of the picture, it should be on the cold inlet side. Terry
