Hello, I have a 36' Keystone Mountaineer. When I run water in the bathroom sink it backs up into the tub. I plunged the tub, and that didn't work. I went in with a cable through the bathroom sink pipe. No good. I went in with a cable under the tub through the drain pipe going to the gray tank. I went in about 25'. Still didn't open it up. I have even put drain cleaner in it and that didn't do it. It appears that the gray tank must have two inlets, because the kitchen sink drains just fine and the gray tank drains fine out the outside drain. Any ideas? The drain pipe is in the floor so I can't access it. Is there a chance that when I go in with the cable it is going up a vent or something instead of clearing the clog before it gets to the gray tank? I called Keystone to get a schematic of how it is plumbed but they were no help at all.
Please help.
