Water pump woes UPDATED!!!!

I need help!!! They say that's the first step admitting you need help. LOL
Okay here are the details. Trailer is a 2015 and has been flawless for the 2 years we have owned it. Last month we were camping without a water hookup. Ran out of water and refilled no problem. Ran out again a few days later and tried filling from the winterization port. Got the water into the tank but when using it started sputtering and spitting like it was still out of water or sucking air. Ended up blowing air into the inlet line and it started working!
We went out this week when we ran out of water the same thing happened. This time blowing air into the inlet line didn't do any good. I removed the inlet line again and attached a hose and stuck it in a bucket. Water pump works as it is supposed to. Replaced the inlet line and then removed the line going into the water tank and put the line into a bucket. Still spitting air. I am at a loss as what to do next.
I am hesitant to start removing pex fittings but will if I have to. Is there a way to pressurize the system to check for a leak? I haven't seen any water leaking anywhere. Some times the pump will pressurize and shut off other times it just runs.
Any suggestions are welcome. I don't want to take it to the dealer. Thanks.
  • Running it dry will put a lot of air in the lines. Are you letting it spit and sputter long enough, with a single faucet cracked open to remove the air? If continually sucking additional air, then you need to find out from where.

  • wa8yxm I had thought of that and checked if the cap was tight. Is there supposed to be a gasket in that cap? Thanks

    midnightsadie I had thought of that too but the pump works as it is supposed to when I attach a hose and stick it in a bucket. When I do that the strainer is still attached.

    What really puzzles me is there is no water dripping anywhere I can find. I would think if it was sucking air it would leak also.

    Sounds like you did not fully close the winterization port valve and it's letting air into the pump. Recheck that port.
