2013 Cambria Fresh Water Tank filling while on City Water

[bbbeebop]

This is the first time this has happened in our Cambria we are hooked up to City Water with a pressure regulator and filter, water valve is I the full normal position  but the fresh water tank is filling very slowly, like over night it will fill approx 1/3 of a tank.  Is there another valve or check valve I could be missing or leaking.  Looking for input.  Thx

There is a check intergrated in the water pump. It may need cleaning.
Also the valve, which needs to be opened to fill the tank, may be leaking by when it's shut.

My guess is the three way valve (fill - city water) has an internal leak. I had one go bad a few years ago.
