Leaky waste tank

[Don Bradner]

I gather from that you've never had a leak you couldn't see?

Near the front (outside) edge below my tank is a strip of plywood support.
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?

When the leak starts, it begins with that large piece of plywood "weeping"
apparently all along its length (as seen with a mirror and flashlight). Water
then flows in all directions 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.

There are lots of places the leak could be (sides, bottom, back) that are not
visible.
