H2O issue

[shark24]

Noticed while camping to first time in a while that there was water under the foam floor covering. Noticed when walking across is outside the bath to the end of kitchen the weight of walking on the floor caused the water to seep to top of he foam flooring. Started looking and water inside the storage area under the bunk had soaked some extra towels we had stored there. We hooked the water hose to the camper and no leaks underneath camper where the water pressure is going into the camper. For sure something is leaking somewhere. Any ideas?
Thank you!

Could it be water on the road forced up through the wheel wells? That is a very common problem on LLs as there are gaps in the wheel wells that let water spray in. The fix is pretty easy- remove the wheels and caulk along the gaps.

Purchase a can of automotive rubberized undercoating and apply to the whole wheel well after you re-caulk. One large spray can is perfect for both sides. If you are going to remove the wheels this is the time to apply the undercoating.

When we were out there was no rain. So not that. We did replace the toilet valve due to it being broken. No water under mat floor until we attach the hose for water pressure. Not sure if it could be something else burst around the toilet area. Water was all in the storage area under the bunk as well. Saturated our stored towels there.

The easy fix has been discounted. Let the difficult detective work begin. Hopefully it won't be like my multi year saga to find a roof leak!

If this problem were mine, I'd check the lines leading to the outside shower. Not there? Then I'd drain the system, attach an air hose and listen...ugh, if it's in the bathroom wall! GK

I had the same problem in my 2016 21BHS. As GK suggested, it was the cold water flexible line that went to the outside shower.

Not so good before and after fix pictures attached. I couldn't find any of the flexible tubing, so put in two straight lengths and a right angle connector.
