2016 HR Vacationer water selection valve
We are on our maiden voyage with this beautiful rig. However, I broke a rule and tried to change the water selection valve to city water, WITH THE WATER PRESSURE ON. Now its stuck on TANK, and continues to fill the water tank. A neighbor spoke of pulling the valve and reseating a rubber O-ring inside. I am mechanically competent, so doing it is not intimidating, but instructions would sure help.
Anybody fixed this problem before??
