Elusive Water Leak


I really enjoyed your training sessions at the Seattle RV Show. I need some suggestions from you. I have a 2007 Navion that I purchased recently. It had a wet spot on the ceiling on the driver's side above the shower. The dealer took it back but couldn't find the leak so they re-caulked all around the skylight and the rear terminator cap. They ran leak tests for three hours and said it didn't leak. They then dried everything out and removed the small stain. This was two weeks ago. Today I felt up there and it is damp again. I will take it back to them, but am worried they won't be so gracious about fixing it. Where would you suggest I have them start to find this leak? Could it be leaking in one of the lights? If they aren't helpful, is there someone you would suggest I take it to. Thank you very much for your help and suggestions. It is appreciated. Donna, (Western WA)


Donna, with so many items attached to the exteriors of RVs water leaks are some of toughest to diagnose and find the entry point(s). There’s truly only one guaranteed method of finding water leaks in an RV. It’s by using the SealTech method. 

Watch this little 3-minute video and you’ll see why.

I’m not sure if your particular dealer has a SealTech machine, but they should! SealTech publishes a list of all companies that have purchased one of their machines. It looks like there is a repair facility in Centralia that has one, but for everyone's benefit, here’s the updated and official SealTech list:

And as I mention in that little video, once water gains entry, it could flow anywhere before it is actually discovered. So I believe SealTech is the best way to go. It’s then up to the expertise of the shop to seal the leak properly. Obviously your dealer wasn't as thorough as they thought they were!
