b. The Toilet
The toilet is one of the standard U.S. makes using seawater for flushing.
The normal maintenance is of the pump. Head manufacturers all produce
pump rebuild kits and you should have one aboard at all times. Probably
the dirtiest job afloat is cleaning a plugged head outlet line. The toilet
outlet-becomes plugged because too much waste was allowed to
accumulate and it cannot be forced around one of the sharp bends which
is of necessity in 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 making the one who caused it
clean the line.
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.
