water leak

When I run the kitchen sink in my four winds 31E, water pours out from above the grey water tank. It looks like its coming from aboe the tank from a drain pipe. Access is behind the lower bunk on the slide, but I cannot see how to get that panel off the lower bunk to examine the pipes. Any ideas??

Look for the flexible drain hose from the sink. It probably wasn't attached correctly to the rigid pipe going to the tank. When you open/close the slide is when it unattaches.

Take the drawer out that's under the oven.

Is there a heater vent below the bunk?

I was able to reattach ours by removing a heater vent in our bath, above the gray tank.

I had the same issue. Seems like a poor design to me. It was "re-sealed" once but has detached again. I am going to a another shop to see ig they can anchor it better.
