herb Posts 7	I have a 10 Gallon Attwood water heater model#GC10A-4E, installed in my 05 Vacationer. Over the past year it has leaked from the preasure/temperature relief valve with increasing frequency. Each time, I go through the drill of turning off the water, relieving the water pressure at the sink, opening and closing the valve..letting it snap back and then re pressirizing the system. It got to the point where I was getting a cup or more a day out of it ( I put a cup under the valve). I decided to change out the valve with a new one. The problem went away for a day or two and is now back!! I also changed the pressure reducer at the water compartment panel. I tested the water temp at 150 deg. F Seems a little hot. Any advice would be appreciated.

Sounds like the water is getting too hot which will also increase pressure causing the pressure and temperature relief valve to do its job, relieve pressure. Make sure the thermostat is making direct contact with the aluminum tank. The spring should be mounted on top of the thermostat pushing it against the tank. Also make sure no insulation is lodge between the thermostat and the tank.

Still leaking from the valve whenever the water goes through a heating cycle after usage. I purchased the thermostat/eco combination at Lazydays and installed them yesterday. The only thing that has changed is the size of the leak...about a quarter of a cup.

Steve Roddy Lazydays Employee Posts 647	Is the water temperature still at 150? No signs of a leak to lose air pocket at top of tank? Rare that P&T valve goes bad so I would not think you had two bad valves.

herb Posts 7	The temp is running about 135 degrees, perhaps just a little more. The leak would have to be at the top of the tank where the air pocket is I would think. From anywhere else it would just leak water. In any case I can find nothing. Although it won't fix what may or may not be a problem, I think I'll just put a drain line from the relief valve, so any leak will be under the coach.

Steve Roddy Lazydays Employee Posts 647	What is the temp and pressure rating of the p&t valve you installed in the water heater? The one Atwood uses is rated at 125/150 psi / 210*.

herb Posts 7	150 psi and 210* That is also what was in there origionally
