2006 Montana 2955RL Tank Leak

[Richard Paden]

Hi folks,
This is my first post.Our Montana has developed a leak in the wastewater system. I keep the valves closed and open them once in a while to drain the tanks. Our Montana sits on a campsite and has not been moved in 8 years. I drained the tanks a few days ago and everything seemed fine. I drained the "Black"tank first followed by the "Gray" water tank next(pull handle right by the Black water"handle". Then lastly I drained the tank with the handle just in front of the tire. Later in the day I noticed that water was dripping from the area where the plastic belly liner meets the frame. I put a small hole in 2 areas where the liner was sagging down and water ran out of both areas. My question is does anyone know how the tanks are configured up in there? I am a "do it your self-er". Thanks for reading my story.

You've got to pull the chloroplast underbelly to see what's going on. Could be a valve, fitting or tank.

I just repaired my galley tank. I had to pull down some of the chloroplast underbelly. I removed the panel above the axles and pulled the one behind that partially down. You won't need to remove the panel behind the axle like I did. While I was investigating I noticed that the brace that held the galley tank had a cracked/broken weld. During welding some slag fell on my hydraulic lines so I had to replace them also. I watched some YouTube videos on how to do it. I mixed ABS cement with ABS shavings and applied over screen door mesh. The repair was much easier than R&R of chloroplast.
