- way2rollNavigator IIIAwesome. Glad you got it fixed and reported back.
- HikerdogsExplorerI don't think you really want to access either the black or grey tanks unless absolutely necessary. We had to do it in our 2001 Adventurer and it was a royal PITA.
First off you have to remove a couple of the side panels. They're held in place by screws on a top and bottom flange. To get to the screws you have to remove the trim belt.
Once the trim and panels are removed you have to remove a set of sheet metal panels between the main floor and the sub floor. Once the screws are removed you have to get a thin putty knife under the sheet metal and slowly break the caulking type seal. The sheet metal panels are thin and the glue/caulking is strong. It takes lots of patience to keep from destroying the panels.
Once you gain access to the tanks you'll find there's very little room to work on them. You have to be a bit of a contortionist just to get to the plumbing connections.
We had a leak where the fitting from the toilet meets the black tank. We didn't know it until we had driven about 250 miles and were pulling in the drive. As we went up the slope you could see black gummy crud dripping out the back of the motorhome.
It took several hours to access the tanks, and another couple hours to flush out the smelly goo. Once everything was clean It was a real chore to get into the area and find the problem.
Once we found the problem we quickly realized the repair was beyond our capabilities. We didn't have the tools or components to replace the broken connection to the tank. In the end we took the motorhome to the Forest City service center. Even though we had already gained access to the tanks it took the better part of a day to repair the connection. We stayed overnight and they leak tested and reinstalled the panels the following day.
It's not a process I would wish to repeat. If we have a similar problem in the future the motorhome will go directly to Forest City. - KevinandHarveyExplorerHey gang! Found the issue. Pulled up the whole outdoor shower assembly and discovered that the Grey Drain Pipe joint had separated! Three minutes later it was fixed. I did call Winnebago Tech and they were great however still no solution to how to access the rest of the tank. So all fixed. Thank You all for your help!!!!
Harvey - way2rollNavigator IIIGoing to assume you know it's the grey by the levels going down on that specific tank? What about the blade/gate valves in the wet bay? Also can you see any connections in the wet bay?
- MountainAir05Explorer IINot your RV, but when we had this I was able to find it and see from the sewage connection compartment door. I was able to find it and took a while to figure out how to reach it. Not easy but did get the bad connection cut out and put back together with out so many joints. Straight runs then cut as needed to get it all back to a working condition.
- IB853347201Nomad IIWhy don't you call Winnebago service? They are very helpful.
- KevinandHarveyExplorerI have been under the rig. The tank is not visible or “mounted under”. Seems to be installed , sandwiched between the main floor and subfloor. Crazy. Can’t find any access.

Thank you! Dennis looking at this diagram, the grey water tank is located closer to the middle of the rig. It is unclear to me how to get access. Worst case is there access from inside under the floor?
Have you tried crawling under to see if it's a leak on the tank itself, or a connection? A camera scope can be had on Amazon for about $20, and are great for scoping out leaks etc that are otherwise physically hard to get to. They work with your smart phone. - KevinandHarveyExplorerThank you! Dennis looking at this diagram, the grey water tank is located closer to the middle of the rig.
