So I was working in my trailer as it was raining out. My windows
have been completely rebuilt, with all new felt sliders. The rain was coming down pretty good outside, and I noticed a trail of water running down the inner wall. No way! I thought, fresh butyl, then a bead of sealant around the whole thing, a leak should be impossible. So I went outside to inspect. All sealing points were fine, but the felt slider was full of water. Now I notice that the sliding half of the window is sitting in the felt. The water that hits this half of the window, runs down the glass, and into the felt slider. The felt then fills up, the drain holes at the bottom of the windows
are clear, and I would assume, should drain out said water. In this case the rain was filling the felt slider faster than it could drain, and the excess water was coming inside. Is this a normal issue? This seems unacceptable to me. The trailer is jacked up as I was doing wheel bearings, it is by no means level, and it's the high side windows
that are leaking. Will this not happen when level?
