[DK on the road]

In my tank bay I have found 2 different leaks that I would not have thought there should be fittings.

The first one, not pictured was behind my water isolation panel. It was a dead-end line with a push on connector. I don't know what this line would have been needed for. This line was zip tied behind a large electrical line bundle. I could barely hear it, (or see it) and once I had taken the panel off and started to remove zip ties, I saw it. This one was only about 18" inside so with a full arm stretch, I could get to it.

The 2nd one was a brass tee with 3 push connect fittings located in the middle of the chassis and above the pure water tank. I am preparing for a longer trip and had not planned on removing both pumps, the water isolation valve assembly and the pure water tank. After about 10 hrs (I'm slow) I got it all out and replumbed the line with a DOT compression coupler in the middle of the chassis and reinstalled the Tee with DOT compression couplers near the DS outer door just before the 2 lines head up the exterior wall. 

I now am reinstalling a new treated wood separator between the tanks, the tank, and all the plumbing. 

Picture don't come out that well or do justice to the location.
