Hot water leak - repairs won't take

Trailer is new last summer. First trip out this summer we noticed water on floor inside cabinet. It was the night before we were leaving so we just turned off pump when not needed and had towels to catch any dripping.

Got home, called the Jayco dealer here about warranty, of course they are booked up forever but was told it was okay to attempt fixing ourselves. So we discovered leak is coming from hot water connection to kitchen sink tap. Tightened compression fitting. Tested. No leaking appeared. Thought we had it fixed.

Next trip out, I checked after doing dishes. Still leaking. Pulled hot water connection apart, discovered gasket inside compression fitting was folded. Drove back to the city and bought a new gasket. Replaced and tightened. Tested again, no leak. Thought we had fixed it. Appeared not to leak for the next day we were there.

Third trip out. Leaking again!! The compression fitting will NOT go any tighter. The leak is much slower than it was. My husband thinks it may be because the hot water hose is too short and pulls on the connection at an angle. The leak appears to be dropping from the bottom of the black screw on connection whereas prior it was coming from the top of it. It's very slow.

Maybe it's their silver crimped fitting below the black compression fitting. Which is something we can't fix as we don't have those tools.

Any other suggestions? I'm losing my mind here.

Three tries with minimum fix and no success?


Time for total teardown, thorough examination and new pieces.


Are the threads in the hot water tank OK? No nicks or missing segments?


Be prepared to cut off the old connector and splice in fresh parts.

Get some "SHARK BITE" fittings and a short piece of pex tubing that way you can make the line longer and it won't be pulling on the connector.

Well it has improved each time. But ya, it's not completely fixed.

We were thinking adding a section would help. I'll look into the fittings you suggested. Not sure if I can get anything like that around here and we won't be back in a city for 6 days. But I think the leak is slow enough, that with a chamois on the floor to catch any of the slow drips, we should be able to make it that long.

We have water hook up this time so are turning the water off whenever we leave anyway, and are out and about biking and sight seeing so the water isn't on full days right now.

Yup. We're on our way to go biking right now and then heading to a friend's site for dinner. So not until late tonight or tomorrow. Meant to grab pics already but I was so sick of unloading and reloading that cabinet that I forgot.

When you remove the black fitting is there a tapered rubber gasket in the fitting?


Also when you look up into the brass portion does it appear that it is tapered on the inside?

Here is a pic of the gasket. This was the damaged one and we've since replaced it.

No, not tapered.

Try putting the gasket with the flat side up against the brass fitting Being that isn't tapered it may provide a better seal
