Kitchen sink drain leak behind cabinet

[Gary CA]

If you have a galley slide then I suggest checking the connection between the white flex drain hose to the rigid ABS. I found a wet note pad on the floor under the galley slide. As I checked into it I saw water dripping from the kitchen sink drain flex hose where it screws into the ABS. I had to empty the under sink cabinet and remove the white panel liner to reach the connection which was loose. The factory installed metal U clamp was already torn from the floor and had caused a kink in the white drain hose but it was still intact. Suggestion: toss a piece of paper under the galley drain connection and check for leaks. The water leaking from mine had been doing so for sometime.

I previously owned an 03 Journey DL 34H. I had to repair that hose on my first outing when the coach was brand new. I'm surprised that yours took this long to leak. It's a really bad design and Winnebago used the wrong glue on the connections. The dealer and the factory both tried to repair and both failed.


The third time I did the repair. I replaced the DWV fittings with pressure fittings (they have much more surface area) where the flex is connected. I used the proper primer and PVC glue that is approved for flex pipe. Also, I installed 3 stainless sheet metal screws through the fitting into, but not completely penetrating, the hose.


After that I had no further problems. I traded it in 2012.

ernieh,
Thanks for the repair tip; will have to keep a close eye on the drain fittings and will follow your lead on a better repair.

Thanks for the heads up Gary. I'll be performing the inspection after I evac under the kitchen sink area tomorrow...
