Unknown leak location 2011 32’ cruiser Patriot

[Robldoit]

I have water dripping through the underside mesh Just about mid way near the frig location, which appears to be clean.Previous owner must have know as the is a patch over a assess cut. It appears to stop when the water is shut off when we’re away. Any ideas on how to determine without removing the mesh? I tried a scope but couldn’t really see anything.

If you are absolutely positive it isn't coming from a water line that you can see from inside, and it starts and stops when water pressure is applied to the system, then the only thing left is to attack the issue from underneath. You can cut small holes in the underbelly and use a small camera on a 3' wand (Home depot/online) to try and isolate the area. I have removed a few bolts and the metal strip along a side of the RV and pulled a small portion of the membrane down to repair a black tank spryer clog. Maybe that would be an option. Pulling the membrane down is relatively easy - putting it back up tight will probably take two people. Good luck and keep us informed of the progress.

Access through the previous owners access cut area. When finished use wide black Gorilla tape to patch the area closed again. Let us know what you find.
