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...

15 yrs old so chances are T&P Relief Valve has built up enough scale that it is NOT a matter of re-establishing the air pocket. Time to replace.
15 yrs old it is well stuck
Try 'tightening' first then try removing. Might have to work back/forth to get it to break free.
Remove the exhaust shield so you can get better access.
And if you have a propane torch slightly heat tank area around the valve...but stay away from valve...it is brass and will absorb heat quickly (making it harder to remove)
Use a breaker bar for extra leverage to remove old one.
15 yr old T&P is a 1/2" NPT-------Atwood changed to 3/4" NPT when they changed design (2004)
