Default Flooding when driving in the rain.

Hey guys we are noticing a lot of water getting inside of our trailer as we are driving in the rain. obviously the rain is coming in underneath the trailer as the water splashes up. Is there a fix for this or have any of you experienced this before and how did you deal with it???

If you know for a fact the water is splashing up, then it sounds like you need to replace the bulb seal that is on both halves of the trailer. Even when I had bad bulb seal I never experienced water splashing up, though I have never driven in extremely heavy rains. We did and still do get dust inside.

Well the carpet and floor are soaked but I don't see any leaks on the ceiling or windows so I am assuming the road spray must be entering the trailer from the bottom. I am not really sure how to know for sure. I figured someone out there has experienced this before.

Cory, what size of trailer do you have as plumbing could be the issue. This year when we were camped in Banff, Canada and with hook ups, we had water leaking from the inlet water connection. Soaked the carpet and part of the floor.

Have you checked the fender/wheel well areas for gaps or cracks? You could get lots of infiltration in those areas. The roof vents and A/C could get water coming through as well. I would think if water was getting past the bulb seal there would be wet walls rather than on the floor.

I'm with Garry here. Check under your sink(s) first for leaks there. Then, if you don't find any, look at all the piping in the vicinity of the water pump.

It would be hard for water to splash up from the road, between the halves, even if there were NO bulb seal. Were the windows all closed? How about the skylight vent?

Agree with all the above. If it WERE road splash, then the curtains would be wet. Even more wet than the floor or carpet, like Jack says. Must be coming from another area. Might be tough, but a camera setup would show something. But waiting for a rainy situation, setting up a video camera and taking the unit for a short trip would be a pain. Water must be coming from somewhere.

Pex tubing, which seems to be the norm in the RV industry is not very forgiving. If you have any connections that get bumped or tweaked, they can start leaking, based on my experiences. I have replaced both hot and cold water lines from the back of my water heater, using brass adaptors, with better quality flex hoses used in house plumbing. I also replaced the pex
that was hooked to my fresh water inlet, which as mentioned, had soaked carpeting and floor. An RV repair shop told me they use regular flex hoses all the time. So far I have not had any problems with the revised plumbing.

Our tanks are empty before we drive.

The only time I had water come in was ice melting from the A/C after running it during very humid weather. I learned then that when weather is like that it has to be run on high speed.
