I recently purchased a used 1998 27 foot ProLine walk around with cuddy
cabin and an electric toilet. We need to empty the holding tank. I have no
documentation for the boat. Are there valves that need to be opened? If so
where are they? Do I turn on the macerator pump? Do I need to run the
electric toilet. Could someone let me know the procedure?



I empty mine by opening the "Port / Sea" through hull valve, closing
the vent lines ball valves and then, after donning my lucky shower
cap, safety goggles, filter mask and raincoat, pressurise the tank
by introducing 12 volt tire pump air into a vent line using an
automotive cooling system flush adapter and a "blow out nipple"
shraeder valve stem that threads into the flush fitting hose
connector, available for RV use or other line purging purposes.
When it farts, its done. It's a good way to test the joker valve.
If it leaks back, it gets replaced, pronto. If not, and after 3
years it still doesn't, we take bets on next time. The jackpot
accumulates, and guests contribute apace. I am considering a snug
fitting, pressure gasketed, plexiglass safety cover for the toilet
bowl, and a new rule that the flushor will collect 1/2 of the pot.
There are only two positions upon which to bet, and the bettors may
form teams, comines, or pools. THet may watch in witness, or absent
fortitude, may await hor's doerves in the cockpit.

As you may perceive the idea revolutionary or hazardous, consider
that submarines use air to dump ballast tanks every day, at depths
and pressures that are classified. My pressure system,
affectionately known as the poop cannon, needs lift the "ballast"
only about 15 inches, max. The poop chute / sea discharge is at the
waterline.

I have not yet had the temerity to try out the two elbo fittings for
the deck pump out fitting, the aimable nozzel of the cannon that
awaits those on PWCs who dare buzz me too closely, portside. The
lift height and pressures needed to permit a forceful discharge at
deck level are as yet unexplored, yet they beacon like skunky
sirens. Likewise, we have as yet not installed the ball valve in the
deck pumpout line (which has never needed using at all) that could
permit a controlled discharge of possibly the foulest weapon not as
yet banned in the articles of warfare and therefore, technically,
still a legal weapon.

The deck pump out poop canon fittings could also be used to empty
the holding tank in the driveway, into a garbage bucket for disposal
down the toilet in the basement, or at the local mall RV plaza dump
out. We preserve our alternatives.

Tire inflators cost $9.99 when on sale, but they are not marine
rated. I love multi use stuff.
