Water pump not working

I just bought a 2001 Terry 5th wheel and I went to try the water pump, and it’s not working.
Before I bought the unit, I flipped the pump switch on and heard it kick on, but quickly turned it off because it did not have water in the tank.

I brought it home and filled the fresh water and flipped the switch, and now all it does is have a very quiet humming noise but no water pumping out.

Is the water pump done for?

    I checked the fuse and it looked fine to me


    Did you just look at it or check it with an ohm meter?

    So I had all the faucets closed and kept the water pump on for about 3-4 minutes. I turned on the cold kitchen faucet and water spurted out like it was pressuring. It then stopped and no water after that. I had to get the kids to sleep so had to shut it down for the night. Should I just leave the pump on for a long time?

    Hook a city water hose to the water inlet and check everything. Open each faucet one at a time. Allow to air to purge out of the lines. Remember the HW heater could have a LOT of air in it. Once you have good water flow out of each fixture, turn off the city water, go back in turn on the water pump and let us know what happens.

    Any chance there is a selector valve right by the water pump leading to a secondary source used for sucking antifreeze during winterizing? If so, try turning it the other way and repeat the steps above

    You did not say if you bypassed the water heater. If not, it takes time for it to fill, and pressurize the system. Using city water to fill lines and WH is a good idea, but the pump should do this on it's own, just takes longer.

    This might be my problem. I will make sure the water heater is full and try again when I get home from work.

    I will report back with what happens. Thanks.
