When I hook up fresh water hose ,I get a leak coming from water tank compartment. If I use water tank and turn on pump no leak and water pressure remains good.Pump only cycles when I turn on water in ...
As I understand it on my rig is that the city water pipe is connected to the output side of the water pump. That city water pipe has a check valve someplace that prevents water from the pump going out the city water connection when it is not used. So your leak would be on the city side of that check valve. That valve may be right at the city water connector.
