OK basic question: boat has a porta potty (actually more than a PP;
it's hard installed in the boat). no holding tank apart from the 3
gallon tank on the potty. it has a drain port for connecting to god
knows where. it was connected to a line allowing direct dumping to
the sea....but, since i don't like my buddies on the gold side of the
USCG busting me, i disconnected it.

question: can i hook a sanitary line directly from the output of the
potty to the pump out connection, and pump out the potty's holding
tank?

will a pump out damage the potty, or, god forbid, blow its contents
all over the head? a buddy of mine did that once on his boat...got
the valving wrong and coated his head. NOT a pleasant thought....

thanks everyone (and where's peggy when you need her?)

I'm guessing a one way valve would prevent a backlash. You should be
able to adapt it for pump out. It'll take some dismantling, and
rigging the piping, as well as drilling the deck to accept the plug.

it looks like everything is in place, including the connection to the
toilet. the only thing missing is the sanitary line from the head to
the pump out connection on the deck. i just want to make sure i don't
blow up the toilet when i flush it out.

You worry too much. Go for it. What's the worst that can happen?
