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.

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

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.

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.

I think some used an o-ring for the cap to seal when tightened.

All the ones I have seen - the cap shouldn’t make any difference, there should be a valve, is the valve fully in the correct position, which is the only thing that matters.

This. Mine has a three position valve on it. In one position it draws from the short hose for antifreeze. In another position it draws from the tank. The third position doesn't work for either as it seems to connect to both the short hose and the tank. That allows air in from the short hose causing problems.

Maybe take the cap off the winterizing (antifreeze) tube and put the tube in a glass of water. Then open the faucet and see if the cup gets drained. That should tell you if the valve is set correctly to draw from the tank or still from the tube.

Does your trailer have a gravity port on the outside to fill the fresh tank? If so are you sure it's full? If you open the drain do you get gallons of water coming out? The winterizing tube is to suck antifreeze out of a jug and push it through the lines and out the faucets. It does not put antifreeze into the tank.

What inlet tube are you blowing air into?

Maybe try unscrewing the aerator out of the kitchen sink and run the pump for a while. These are diaphragm pumps and are not damaged if run dry so let it run for a few minutes. I once helped my brother with the same type of situation and there was a bunch of sediment clogging the aerator. And this was after he owned it for a few years.

If you have an outside shower, check to see if the knobs are turned off. If on and the shower head turned off, the head loves to drip.
