Hot Water --Help

I thank all of you that came to our aid. Yes, it was the check valve. There is a good chance there will be no screaming from the shower due to having only cold water. Thanks again and again.

The check valve has gone bad. Replace it.

More likely it cruds up with mineral deposits and sticks closed.

THE SOLUTION
#1: (Temp or see WINTER note) Turn off water, Turn off heater, bleed off pressure, remove water line from check valve, use long noose pliers to gut the valve, re-connect and enjoy.

#2: replace check valve if necessary or add 2nd valve if you can not remove the original.

WINTER NOTE

Three water heater bypass sytems 1,2 and 3 valve, IF you have SINGLE valve and you use the WET method of winterizing you need that check vlve. If you have a 2 or 3 valve set up the check valve is not needed, nor is it needed if you use the Dry method (Weay Heay Blow the lines out, several times) or the "S" method like I do (Southern Georgia just now... Full time a HOT, water heater does not freeze, only a cold one)

It's probably not convenient but what happens if you 1. turn off the pump or the campground water supply then 2. disconnect the hot water line to the faucet 3 reinstate the water flow (pump or campground); Better flow?

Does cold water run? Did you check the aerater at the faucet?
