Leaky waste tank

[davidkerryedwards]

Most I have been able to see. The ones I couldn't see closely enough to pin
down exactly,
I just patched a larger area to make sure I fixed it. Sounds like yours is not
one of those.

Behind that
there is an air gap, then plywood that begins at the center of the drain and
goes back
(toward coach centerline) an unknown amount. Looks like it is quite wide, maybe
goes all
the way?

including under the forward plywood strip. Using the mirror, it appears the
bottom of the
tank is dry forward of the larger piece of plywood.
