Leaky waste tank

[Don Bradner]

Anybody ever have to deal with a leaking waste tank?

Mine started leaking a few days ago, parked in my driveway with, at a guess, 10
gallons of fluid in it. I pulled the shroud, emptied the tank and dried things
out, then today filled it until it started leaking. Took to 3/4 full before
leaking became obvious, and it quickly grew. So far as I can tell it is not from
anywhere around the drain - appears to come from somewhere further to the rear.

I'm guessing my only option is to pull it and look. I'm taking it to my local
small RV repairer tomorrow - as usual they will be happy to have me do most of
the labor under their direction and with their tools.

I hoping they will have good ideas on how to get it off the valve in order to
get it turned to come out, but I'm wondering if someone has done it on a PT-40?
