Hi. howgozeit. I just saw this and I have a similar problem. But, as you may recall my 05 has no valve that looks like that. My guess is that the city water is pushing through the water pump, filling the fresh water tank and eventually leaking at the point of least resistance. This happened two years ago and I replaced the water pump. It is happening again. There is a shut off between the pump and the fresh water tank that I can close and stop the flow back to the fresh waater tank but then if I want to use the pump I have to go below and open the shut off. Is there a one way valve somewhere? What am I missing?
