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....

Had the same thing happen to me, after draining the HWT the check valve on the hot water tank outlet was stuck open. It's only about 3/4 of an inch long in reality, and easy to miss. You should drain the HWT, shut off the input valve to the HWT, open the bypass and then will all taps shut maintain pressure BEFORE you let the pressure off and then introduce the pink.
If the check valve is stuck open pink will fill the HWT and splash out on the ground with the drain plug open. It takes a lot of flushing to get that nasty bugger out of the HWT tank... then change the faulty valve, then do it right.
