(SOLVED) PEX Fresh Water Drain Pipe Spins

I have a 2012 10th Anniversary Surveyor SV264.

I noticed the fresh water drain line started to spin(I can turn the blue pipe a half turn) and was wondering if anyone knew what knew what kind of pex connectors are used.

I know shark bite fittings spin, but with all the insulation under the trailer I am unable to tell whatís up there. It might have just detached from the foam insulation they sprayed in there and has always spun... not sure.

Doesn't seem that there is a strong leak since water is not rushing down. I did see a little water towards the top. My fear is that if it is leaking leaks it would do so in the sealed underbelly and not really show itself until it damages something. I'll be driving back out to storage today to see if it's wet.

I will be doing the obvious and call the dealer today, but I thought I would open it up for discussion here. Has anyone run into this?

For starters, Pex is it's on thing, with crimp fittings. As for it spinning, you need 2 wrenches to take the cap off, one to hold the pipe, the other to spin the cap. All the fittings are plastic, and won't stand a lot of pressure from twisting or bending. Look in the cabinet above the drain line, and maybe you can see the crimp connection. Borrow or rent a crimp tool, Pex 1/2 inch, and maybe re-crimp that connection.

By the way, shark bite connectors seal with an O ring, that is why they will spin.

I dont think the Fac. would use (Sharkbite) fitting$$. They normaly use the sleeve and crimp Pex connectors. When proper crimp pressure is used my Pex fitting dont rotate. Youroo!!

Ditto,

If his factory tube is spinning the upper crimp fitting has most likely failed and could be leaking. The belly Coreplast covering will hold A LOT of water before it comes down. Drill a small hole in the belly covering at the lowest sag point and see if water drains out.

If the lower fitting itself is spinning it is normal as the plastic part of the fitting (just below the crimp) is spinning just above the threads.

Following up this thread with the fix.

Dealer contacted Forest River for me who said that there was another threaded plastic fitting crimped to the Pex on the opposite side.

I simply removed 7 of the coroplast retaining screws on the frame which gave me enough give on the coroplast to fit a crescent wrench in and tighten the connection.

Thanks for everyone's input!
