I have a 1999 rexhall 32 ft m/h. On my last outing I was informed by camp ground security that I had a water leak. being late at night I shut off water supply. Found the leak to be from the fresh wate...
I thought the over flow was to let you know when the tank was full so you didn't have to go inside to check the gauge. Don't understand where to put a check valve. When filling your tank there should be a valve to turn for tank fill are water to the coach! Good luck
