Are you thinking about installing a new tank, or replacing yours with an
old one from a similar model of coach?
When I last worked on a in-use black tank, and dealt with that stinky
unsanitary mess, I vowed to never work on another tank that was in use.
I take a sawzall, and cut all the pipes, disconnect and label the
wires, and remove the toilet. Then I lower the old tank, duct tape closed
all the openings, and put it in the back of my pickup for a trip to the
landfill.
Then I temporarily install the new tank, mark where the pipes enter
it, and remove it and cut all the holes with hole saws . Then, put it back
in place. Hook up all the pipes, and that's about it. Wear gloves, and a
good respirator, and safety glasses.
That's how I do it, when I can't get out of it.
