Hot Water Pressure Relief Valve
How difficult is it to replace the relief valve in a Atwood heater. Is there any tips or suggestions for this. Or is it just use the tool and apply pressure to unscrew it? 15 year old Atwood heate...

Before you replace the t&P valve try the following;
Your tank needs an air pocket at the top or else it may leak so,
Get a can of PB BLASTER and spray inside the drain opening then
turn off water supply and open a hot water faucet that is higher than the heater, now go out to the heater and open the T&P valve until water stop draining out
Spray inside the drain with PB BLASTER again you are okay if some gets into the heater, you are trying to spray the sealing surfaces which may be rubber, then close T&P valve
Now go inside and close the faucet and lastly turn on water and after the heater is filled start the heater. Do not open faucet to purge air
This may save you a lot of grief takes about 10 minutes
