Water Line Leak At Compression Fitting

[lifercars]

We recently purchased a new 2012 Jay Flight 32TSBH and have camped in it three times. We love the layout and features that Jayco put into our camper. On our last trip, I noticed water leaking from the compression fitting for the cold water line under the bathroom sink. The leak is a slow drip and the fitting is not adjustable. I tried putting a radiator hose clamp over the fitting but that didn't stop the leak. I then tried using a small vice grip which also didn't work. It doesn't seem to leak all the time, just after we use the sink. I was able to contain it by placing a plastic trash bag on the floor and replacing a kitchen towel every so often. It was a nuisance but it let us finish our stay. The leak is at a "T" junction which also feeds the toilet. The dealer suggested a service call but noted that the cost isn't covered under warranty. Has anyone else had this issue? Do you know how to fix these fittings? Does anyone have any suggestions before I consider towing to the dealer (40mi) or paying for a service call. I couldn't post a photo with my iPad so I'll try later on a laptop.

We replaced the fittings on our last trailer in the shower area.
I do not have photos anymore but they were basically plastic flexible hoses / pipes and they where joined together with compression fittings. They would be really easy to replace/repair by just buying the new parts, but my issue would be that you have a warranty and so why should you have to do that.
My suggestion would be have the dealership repair it... However in the mean time, if you put enough clear silicone on it while it is dry, it will likely stop the leak until you can have it repaired. I know that the silicone works, because when we changed our plumbing in our last trailer we closed off one line.. and we capped it with a compression fitting and covered it with a good layer of clear silicone and it never leaked.

Thank you Lady Wendolyn, I'll have to add silicone to my "tool stash" so I'm ready next time.

Here's a snapshot of the compression fitting where the red arrow points to the leaking one. I first used paper towel to catch the water and later switched to using a small kitchen towel.

You need to tighten the pex crimp to get the leak to stop. Tile clippers work in some cases if you don't have the tool. Another thing that might slow the leak down is a pressure regulator from the city supply if that is when you experienced the leak. If leaking while on the pump then it will leak more while on a city connection FYI.

I would let the dealer do the repair under warranty.

3'senough, great advise. It would be a quick fix if you had the right tool, and will certainly be something I'll pick up in the next few days prior to our 8 week trip starting on the 10th.
Thanks for mentioning this.

Thank you 3'senough for the tip. I do have a regulator on the city hookup but I'll look for tile clippers at the local Home Depot (hardware store). I didn't have any tools with me aside from the usual "home tool set" comprising of a few wrenches, sockets, and screwdrivers. I noticed the leak before the local Walmart closed so I was able to buy the vice grip and radiator hose clamps but they didn't do squat.

As for the repair, I am planning to take it back to the dealer to get it fixed under warranty.

Thanks everyone for the tips.

What pressure do the plumbing systems need to be at? Pressure regulator is something I do not use, but I will be.
