Check valve between FW tank and city water?
I've drained my fresh water tank completely, yet after a few days I end up with more water in the tank while hooked up to the pedestal. Is there a check valve allowing water to seep into the FW tank ...

On board pump discharge and city water inlet line are tied together (same cold water line)
So there are 2 check valves in system
1 is part of the city water connection assembly so when pump is ON water doesn't come out city water connection (running down side of rig and causing pump to cycle
1 is part of pump assembly so when connected to city water backflow thru pump doesn't occur (overfilling fresh water tank)
Sometimes just running water pump will clear debris from check valve
Sometimes disassembling pump and washing check valve/diaphragms will resolve issue
Installing a 1/2" in-line check valve in pump suction line also works ($10)
Then of course there is those that have 'water panels' in wet bay where you can fill fresh water tank via a 'fill' valve when connected to city water (vs usig a gravity fill port).
Fill valve could be problem.......not closing/leaking
