Improper water line clamps result in leaks

[Sky]

I have a 1700BH. I noticed water dripping from the front left side corner after an outing. Investigation showed multiple slow dripping leaks from 3-4 line in the area of the water heater. Winnebago used PEX crimp fittings on braided PVC flexible lines, so of course, they leaked. I'd guess there are other posts describing this problem. It looks like W used PEX crimp fittings on all lines, whether they were PEX tubes, or not. I find this a little bit incredible. I wonder how many fittings are dripping under the trailer? Yet another repair in progress.

I've got the same drip on the hot water valve at the water heater, and have seen photos in Winnebago Facebook groups of the same exact problem. I bet this affects most, if not all of these trailers.

I'll be dealing with mine in the spring.

I purchased a PEX ring clamp cutting tool. I'm going to cut off the offending clamps and replace them with stainless steel adjustable ring clamps. I'll update later if this approach was successful.

It is an issue on some Winnebago motorized, too. They also used PEX clamps on the flexible lines that isolate water pump vibration from the PEX tubing on my Vista, and they had very slow leakage. Replacing them with stainless steel hose clamps resolved the issue.
