I'll post some pictures soon, but I'll try to describe it first. My efforts to fix the leak in the slide have been a success. After two good rains and some water testing the floor in the slide has remained dry.
The floor in the main area, not so much.
Finally did an extended test... attached a sprayer to the ladder and let it rain on the slide roof.
Everything appears to be working fine.
The sweeps hold off most of the water. Some water sneaks in behind the side sweeps at the gaps where the side trim pushes it out. I imagine this is pretty normal and most of it runs straight down.
Problem is some of it manages to wick across the sweep and get into the channel between the sweep and the inner bulb seal that the fascia of the slide smashes against when it's open, more of a weather seal than a water seal. It's not really a problem, its still all rubber and plastic.
As it runs down these seals to the bottom if falls into a black plastic "cup/cover" for lack of a better description (which I will post pictures of). It's held on by 3 bolts and doesn't appear to have any weep holes in it. There was a slow drip from this cover at the inner most corner (under the floor insulation area).
I could imagine in a long extended rain that the volume of rain getting dripping from the bottom of the sweep and bulb seal might exceed the rate the cup can drain. If this happened, the cup is nearly level with the floor, the carpet could soak up water and distribute it across the floor. We've never had it that bad, but the carpet got pretty wet in this last rain.
This would not affect the RV while the slide is in because the outer bulb seals are doing their job of shedding water before it even gets in.
Take a look under your slide, are there plastic corner pieces under the the trim?
What do you think?
