New Skyline Trident with fresh water leaks

We just purchased a new 2015 Skyline Trident 326 Trailer. We had it towed 100 miles from the only dealer in the area and set up in an RV Park to use and get familiar with. We had a small 25 foot motor home prior so we really enjoy the space of the new trailer.
We've been in the trailer 1 week and have been fighting water leaks under the kitchen sink. So far we have had a mobile tech fix the drain hose connection under the sink. This was after finding the P Trap under the kitchen sink and bathroom sink totally loose and dripping water. The next morning I find the area in front of the kitchen counter is still soaking wet. Everything under the sink looks dry. Then I look in the outside kitchen sink area and find that one of the braided nylon hoses is spliced with PEX stainless steel crimp connectors. Wiggling the hose results in water spraying everywhere. Replacing that with a nylon barb fitting and stainless hose clamps stopped that one. The next day more water under the sink area, but only a little. Much feeling around and I find a PEX adapter fitting for the faucet hose on the red hot water tube is leaking when the hot water hits it. Again the fitting is using a PEX crimp ring. My old motor home had PEX fittings all over it and never once had a water leak. With Skyline being sold to Evergreen RV, warranty discussions are non existent.
So two questions:
1. Since I found two bad PEX crimps, should I expect more?
2. What is the best way to fix these PEX fittings?
Sorry for being so long winded, but sometimes you need to relieve the stress.
  • PEX Stainless Steel Clamp rings........raised section on ring that gets 'Pinched'. Clamp tool can be used on various sizes of clamps

    Copper crimp ring uses a specific size tool for each size of crimp rings



    Seen both at Lowes


    Different PEX Connections

  • Are you certain those stainless fittings are PEX crimp rings? I've never seen them in stainless. I'd be guessing that the crimp connectors are a different standard than PEX. Your braided hose is NSF 61--certified good for potable water, made by Camco, and the abbreviation FWH = fresh water hose.

    As was mentioned, the Sharkbite fittings, although expensive, fit a variety of different pipes.
  • I wish I were closer to the dealer. Evergreen RV, who now owns Skyline, also handles warranty work on Skyline RVs and is not very responsive about using mobile repair services.
    Just found more leaking joints where they used PEX Stainless Crimp connections on a white 1/2" braided hose labeled NSF 61 CAMCO FWH.
    We're enjoying what works and working to get the leaks fixed. Probably won't see any warranty support.
    Thanks for your interest.
  • I can relate to your problems. We bought our New 2015 Skyline Dart and have had the same exact issues. If you have an outside kitchen make sure you check all the lines there. That gave us the most trouble. We had it fixed 3 times already by the dealer and the sink is still not usable. In addition, we had a gray tank crack before we were ever able to use our rig. Not to mention all the little things that have gone wrong that screams bad craftsmanship. I hope you are able to get everything fixed and are able to enjoy your Trident.
  • Your right, PEX tubing is too stiff for a barb connection. The place where I used the hose barb was a splice between two pieces of nylon hose, not PEX tube. I have found a number of spliced nylon hose connections under the sink, all done with PEX fittings.
    Thanks for your quick response.
  • Sounds like the PEX crimp tool was not used correctly by installer so I would be suspect of other fittings/crimps failing

    Using a barbed fitting and hose clamp on PEX will also result in leaks...PEX is too stiff to be compressed around barb fitting by hose clamp to properly seal.


    Go to hardware store
    Get PEX cutter tool
    Get some 1/2" PEX fittings.......Sharkbite (Home Depot)/Gatorbite (Lowes) work VERY well but are expensive
    FlairIT fittings work well
    Sea Tech (by Watts) are ones I prefer.

    PEX has to be cut clean, straight, no burrs

    Might need a length of PEX incase line is too short after cutting to get rid of crimps.
    You can use a Dremel Tool with cut off wheel to cut across crimp......or fine tooth hacksaw. Just cut across crimp enough to weaken then use pliers to remove. Don't cut into PEX

    Personally I just cut PEX into and redo the whole works vs trying to cut crimps off



    Good luck
