Leak under bathroom sink
We have a 2016 jayco bh. New to us! We have a leak under the bathroom sink. Anyone else had this issue? It’s the top white pipe that’s leaking around the area of the black piece by the clamp

There is an inexpensive tool available form any store that carries PEX plumbing hardware and supplies.
You may be able to just re-tension the clamp or remove and replace it with a new clamp.

You might try just tightening the black fitting. I’ve had small leaks on those and they just weren’t tightened enough. Simpler than messing with the clamp if it solves it.

So those black pieces tighten? So hard to get in there and see. Tight spot!

It should thread on — just hand tighten. Definitely hard to reach.

That's the hot water side, and they do need a little tightening after the hot water softens the sealing cone up a bit.

You will need a Basin Wrench unless you have tiny hands.

I had to tighten similar fittings on my outdoor kitchen faucet and hot water heater because of leakage.

I've worked with pex fittings for about 25yrs now. The crimp rings don't usually leak unless they are disturbed. This could be a simple bump of the line that you don't recall doing however or travel day bumps. I agree with JFlightRisk the hot side has more potential for leakage do to the heat expansion on the seal a the the fitting connection to the faucet. The cone washer/gaskets tend to get a shape to them over time and harden. I would suggest starting there snugging it up( Gl from the looks of that picture). I would also suggest checking the local hardware for these fittings particularly the cone gasket and getting a package just to have on hand. There are a few variations just pick up a few they are cheap enough. GL

A new Cone Washer and retighten would probably fix it. I just changed a faucet assembly and had a leak at first because they barely gave enough Pex on one side. Had to end up stretching it toward the faucet while tightening. Yours looks just like mine. I carry several extras now, since I saw how it is made. Probably not the crimp clamp.
