Hot Water Pressure Relief Valve

[Rambler]

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 heater.

Thanks in Advance

As the other person said, Roughly as hard as hooking up a garden hose to the park water spigot.

TURN OFF WATER (or bypass the water heater) turn off heater, Remove drain plug and replace with a short tube so as to get water out past the edge of the RV. remove TPR valve (unscrew) go to Lowes, home Depot, Sears, Joe's hardware, most any plumbing supply, Hand to customer assistance clerk, get new one, pay, screw back in (Brass should not need tape or putty but you can if you like) remove drain tube, replace plug (See above comment applies to nylon as well)

Restore water, restore power.

Okay thanks, I have already tried to turn but couldn't move?
The heater is about 15 years old and runs very good.
Didn't know if there was some secret method of getting out besides muscle.

Very simple...unscrew the old one, and replace...Use a couple of wraps of Teflon tape on the threads.

Home Depot, Lowe's.
