[C320-list] Waste deck fitting

[Dave Hupe]

 I did an extensive job in 2018 of replacing all of my waste tank sanitary hoses (including the waste pumpout hose), the intake water lines and thruhull valve feeding the toilet, and replacing the tank vent hose.  My boat is 1994, so this may not be the same for you.
The medicine cabinet removal was very easy.....just remove the screws around the cabinet perimeter and pull the cabinet straight out.  Access to the higher cutout for the waste pumpout hose and fitting is much more difficult.  It required removing the cover panel that is above the shelf over the medicine cabinet.  To do this, I first had to remove the boatboard shelf strips, remove the teak wiring cover behind the fluorescent light, and remove the mount screws of the light fixture (first must remove the frosted lens cover, bulb and shield behind the bulb) so it can be shifted out of the way.  Next, turn off all boat power and remove the electric outlet cover, disconnect all wires from the outlet (tape/mark the wires where they mount for reference), then completely remove the outlet.  
Lastly, remove the screws from the back cover panel itself and try to pull/pry it gradually out/off.  As you do this, feed the wires back into the hole in the wiring outlet box.  My panel was very difficult to remove because I believe the plywood of the panel was slightly swelled from past moisture problems.  Once removed, I wound up removing the perimeter rubber trim on the panel (just stapled), trimming 1/4 inch off each of the wood ends of this panel, then reinstalling the rubber trim before reinstalling the panel.....much easier to put back on than take off!
Once the back panel is removed you will see a high cutout in the fiberglass that exposes the waste pumpout hose and lower part of the deck fitting, as well as the waste tank vent hose and the vent fitting.
Hope this helps.

 I finally decided to dive into fixing the leak at the waste deck fitting. I have things pulled apart but have absolutely no idea how to get back behind the medicine cabinet in the head and from the sides to get at the hoses. I’ve figured out how to dismantle the medicine cabinet but what else do you have to dismantle to get back behind there?
