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?)
