much toilet paper is forced into the outlet line; it plugs or jams around one of the sharp bends that
is part of the outlet line. There is little to do other than break the line at one of the joints and use a
plumbers snake to clear the blockage. This type of blockage is best prevented by a good Captain’s
briefing to all new guests prior to departure from the dock. A prominent death threat signed by the
Captain and taped on the lid of head will remind your guests of the unique nature of the “Marine
Head” which is not a common household toilet.
Toilet operation and maintenance in salt water is enhanced by the periodic use (every three
months or so) of a cup of Muriatic acid poured down the toilet. The acid chemically removes the
calcium deposits that slowly choke off your outlet lines. A cup of cooking oil will lubricate nicely
your marine head’s seals and allow it to work smoothly. Keep your head clean. Take care of it. I
have never seen a business in the yellow pages that does marine head cleaning or fixing....one
day....sooner or later....have fun!
c. Sinks
The galley and head sinks work the same. They are drained straight overboard through a check
valve and through-hull. If the sinks refuse to drain, it is generally because the check valve is stuck.
Look at the drain hose and you will see a bronze cylinder with a hexagonal fitting on top. A sharp
tap will usually free the valve. If this fails, remove the hex fitting and clear the valve.
