That hose that melted? It’s the hose that links the fresh water tank to the exterior non-pressure outlet.

I discovered this when I tried to fill said fresh water tank and noticed water pouring out of my coach.

As I stop gap measure, I removed the melted section and plugged my water hose directly into the line going to the fresh water tank. But if I ever want to sell this rig, I’m going to have to do some major taking aparting to splice in a new, non-melted, hose.

At least, my tanks look okay….
