Water in pan under fresh water tank
I have a 2005 Safari. There is the classic white plastic fresh water drain valve between the wheels but there is also a radiator style drain valve in the pan that holds the fresh water tank. When I hook up to city water, and turn it on, water under pressure comes shooting out of that radiator fitting. The strange thing to me is that with the radiator valve closed and I turn on the city water, it will pressure up to city pressure and by pressing my ear to the inlet fitting of the hose, I can tell that water has ceased flowing into the trailer. Then, with the city water turned off, when I open the radiator valve, the couple of cups shoot out until the pressure bleeds off and the pan is empty. It seems that only about a couple of cups of water will enter the pan. If I leave the city water on and the valve open, it will just shoot out city water under pressure forever. This cannot be right. How is fresh water getting into the pan in the first place, much less under city pressure? All of this while the fresh water tank is empty and the plastic valve is open.
This does not strike me as a check valve issue and I have tried the ideas from this forum to unstick a check valve with no change in how the pan appears connected to city pressure. Any ideas, Airstreamers? I figure I am going to have to drop the pan and the tank to fix the problem.
