Fresh Water

[Larry G]

Good Morning, I am having an issue with my fresh water tank filling and overflowing when i am hooked to city water. Is there a check valve in line somewhere that keeps the water from flowing into the freshwater tank?

Larry, there is a check valve built into the water pump. Sometimes there is a little bit of debris that causes the valve to not seal. SOMETIMES you can run your pump and clear it, but if yours is like mine it seems to be a hit or miss. Mine does it every once in a while so what I do is keep the winterizing valve closed unless I want to use the pump. Don't know what your RV has so not sure if that will work on yours, but you could put a check valve in just past the pump to fix it.
