Fresh Water Tank

Ok.. Here is the situation. I emptied my fresh water tank last week because we are staying for the winter in a full hook up park. When I checked the other day it was full. I left the valve open and noticed that a small amount of water is still running out. It seems that it is getting some water from the park water supply somehow. Also, the fresh water pump will not run now.
There is a switch/valve for the city water supply and tank fill. A bad valve ??
I bought a new water pump but have not put it in yet.
Thanks for any help.

Hello Jim, As far as the fresh water tank filling, you got it, the only thing that it can be it the "fill valve" leaking by, try exercising it, on/off and see if there might be something in the seat that you can flush out before replacing it. As far as the pump, is all the city water pressure off it? if the pump pressure switch is satisfied it will not run. Disconnect the city water and see if it works, if not , turn the pump on and check for 12 VDC at the pump, if no power find the fuse, check for power at the fuse.........

The check valve in the pump is probably leaking. Your new pump may be the fix.
