After wetting our coach we discovered three leaks and a ruptured insta-hot from our RV dealer not correctly winterizing the system. They fixed that problem but we continued to have a leak issue. After the third trip back for repairs, and still leaking, I removed the water bay panel – inside the basement to view into the inside of the bay and discovered a cracked grey water ABS drain pipe. I was able to replace the 20 inch section that had cracked all along the seam through the access hole behind the towel dispenser (no easy task). After adding water to the grey tank I still have a drip coming from the next section of piping after the 45 degree bend up to the tank itself. My question is if the abs piping is glued to the tank or held in place by a grommet. Before changing the bad section there were no leaks in that area. Next question if it is needing to be replaced, how difficult is it to remove the exterior stainless panel to gain access to the inside of the bay to replace the next section.
