Galley Tank Leak When Dumping?

[Rich Lazz]

I have a problem with my galley tank....drain the tank and it dumps but it also leaks onto the under carriage sheet material. A bit of a rookie so I don't know the name of the sheet material covering the under carriage. Can this material be cut? replaced? part of it cut out and patched over? At this point I first need access to fix the plumbing issue. Any help would be appreciated.

It really helps to get correct answers if you tell us the Year, Make, and Model of your Montana. The best way is to add the information to your signature. Click on

The bottom covering is probably coroplast, a corrugated plastic. It is held up by screws (or nails on newer models) which can be removed to gain access to the plumbing. You can also cut a flap (make sure the opening is towards the rear) to gain access and then seal it back with Gorilla Tape or Scrim Tape.

Dropping the coroplast is usually easier, especially if you have a dropped frame models.
