2017 Thor Conquest Water Pump

My best friend just bought a 1017 Thor Conquest MH on a Ford Chassis and is having trouble with the fresh water pump not turning off after the water faucet is shut?

Any help would be very much appreciated.

    IF he has a water panel with switches/valves then have him check the 'Fill Valve' ----needs to be fully closed or pump can not build enough pressure to shut down.

    Other thing.....all air needs to be purged from system ---hot/cold system not forgetting outside faucet


    If pump has an internal bypass then adjustment to discharge pressure settings and bypass open/close settings may be wrong ----discharge pressure higher then bypass full open setting---never reaches discharge set point
