Is this a check valve? This is what I have on the outgoing (top) of my hot water heater.
No that is not a check valve.
But it is the source of your problem.
It is a 'mixing valve'. Combines cold water with VERY hot water to give you a constant temp hot water.
It is clogged up with sediment/scale
Sometimes you can clean them out......remove and soak in vinegar.
Otherwise.......replace. About $140 for an Atwood one.
Your water heater heats the water to about 160*F and the mixing valve is set for roughly 130*F output.
Thank You Old-Biscuit. I was searching and searching last night for a check valve that looked like mine and got nowhere. Now I know it is a mixing valve. Just called a local RV guy (only game in town apparently) and he wanted $220 for the part. I now know the part is $120 so that guy just lost my business. I don't mind them making a small percentage on the product, but near 100% markup is offensive. I'm going to try and do it myself. Thanks again :)
