Water heater bypass not working?
So I'm winterizing my trailer today and at first I don't know where the darn water heater bypass valve is. I finally locate it under an access panel which is under the mattress to the front queen bed....

If you only have one valve to bypass your water heater then it is
the system that uses a check valve in the top fitting in the water tank to prevent afreeze from entering the water tank. I had to change one today....sounds like yours needs changing to.
This gets my vote. Remove the check valve from the top (inlet) fitting. If you can blow air thru both ends, it needs cleaning or replacing. They like to attract calcium deposits...and that keeps them from closing completely.
