FW tank fills when fw hooked up via hose.

[D_E_Bishop]

Our 2002 Winnie 32V water tank fills when hooked to shore water. All valves are in correct positions. I am looking for the exact location of check valve, if there is one. I looked at on-line PDF but not labeled clearly. I did not se any CV just V designations.

I know it could be a leaky valve and they are all plastic. Both shower faucets are shut securely. Any ideas.

You got me,dude. My kind of humor!

Water pump has an 'internal check valve' ---- a diaphragm ---- that seals off to stop backflow thru pump.

Also if you have a 'Fill' valve it can be leaking thru

Disconnect pump suction line and see if water runs out (back thru pump) when using city water.
If it does......install a in line check valve (Shurflo has them) in pump suction line ($10-15) Problem solved.

If no water ...then fill valve is leaking thru.

X2 I had the same problem once, and running the pump for a while solved it instantly.

Look for a check valve in the 12 volt water pump. If you can disassemble, maybe just dirt in the valve. Replacement pump heads can be found on ebay if needed.
