Javelin: Thanks for the reply and the link. I can access the hose and tank connections by removing the storage area floor under the sink and lifting it up. The stiff hose and the fitting going into the grey tank are very accessible. After looking at the link and what others have to work with, I’m more fortunate than most. The elbow that connects to the straight pipe going into the grey tank was just barely connected. Glue was the only thing holding it there. It won’t go on any more due to a support bracket that is in the way, of course it came off when the slide was retracted. I can’t get any more drop in the spa hose because it has to lay under a support for the sink floor. Using swimming pool tubing looks very promising. I called Thor and asked the rep if he knew what the canvas was supposed to do. He had no idea what I was talking about and asked for some pictures.
