Water Intrusion In Bedroom Slide!

I had a couple water problems similar to yours. One, was a slide out topper had some water seepage thru a seam. The water ran off the top of slide, down inside the sweep and onto the carpet right next to the side of the bed. I sealed the topper seam, so the water would run off instead of thru it.

Second water problem next to the bathroom sink, other side of the wall actually in the bedroom. Floor would get wet at weird times, one was after I washed the coach. I thought this too might be a slideout sweep problem but it turned out there was a two inch round access hole drilled into the floor which was covered with carpet. This hole was inside a rear wheel well. When I washed the coach wheels, I sprayed water up this hole which soaked the carpet padding and the sub floor. I had to rip up the carpet, dry out the rotted wood, patch it, then patch the carpet. I filled the hole with foam crack filler. This bad section was between a slideout and a wall, and the repair is not noticeable at all. Point is, leaks can come from some unexpected places.
