Hi, I own a 2017 KZ escape. I am replacing the freshwater tank, the original cracked. I noticed that KZ used some sort of white sealant on the hose barbs. It is a non hardening white sealant and it seems to have fibers in it. Anyone know what this stuff is? Any suggestions for extending the lifespan of the tank?
TYVM,
Stan

You only need a sealant like Ace pipe thread compound on the pipe threads, the barbs don't need it with the exception of the large diameter gravity fill hose where silicone sealer will work. Hopefully KZ didn't attach PEX tubing to hose barbs, they do that in some applications. Be sure that the water tank is properly supported and there is no stress on the attached plumbing, often there is minimal support. Post photos if you need addition input.

Post photos if you need addition input. about 1/2 my fresh water system had white braided hose on PEX barbs, guess what leaked. All I can say is why, PEX is likely cheaper. I now carry a couple sections of PEX in all three colors with PEX clamps and a crimp tool. |

As been said, the keys are to support the tank in every way possible, also make sure none of the fittings have strain- a hose that is pulling on a fitting can causes stress in other areas.

I had that problem with the hose going to my toilet. Luckily, I saw it dripping before it pulled loose. I put in a 1/2 inch barb to 1/2 inch threaded and a real toilet connector. I replaced the pex clamps on the braided line from my fresh water tank to the pump with screw clamps. They use pex clamps because it is quicker. |

I forgot I also have a hand full of the screw clamps for quick repair but change the fitting as needed. Replace hose or the fitting as needed to make it permanent. |

Probably because the white PVC vinyl tubing is more flexible and easier to install at the factory.
