Found a difficult to repair air leak - DK on the road - 01-07-2025

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.

That definitely looks like a pain in the a** location. Good call on changing out the board in the middle. Come spring time i think I'm going to remove both tanks in my wet bay and clean things up and reinstall. having the peace of mind when heading out from Alaska will be nice.

Who would've thought they would put a fitting somewhere that was so hard to get at, especially a push on should of extended the lines and made it easy to get at

On mine, the tee fitting comes from a manifold under the coach rear bulkhead, enters and divides for the air operated dump valve and step cover. Mine was already compression fitted. But yes, I could not reach those fittings without pulling the tank or I could fish in a new longer line and place new tee fitting closer reach.
