Marine Lavatory (aka Head)

• The marine lavatory is a complete, compact lavatory. There is a marine toilet,
wash basin, and shower. Some important points follow:
• Marine toilet (aka marine sanitation device (MSD))
o The marine toilet empties into a holding tank on board the boat. The
holding tank must be emptied by scheduling a pump out. See the Pump
Out procedure for details. There is a warning light in the lavatory to
indicate when the holding tank is full.. When the light is lit the tank is full
and the toilet cannot be used until the tank is emptied. DO NOT WAIT
FOR THE LIGHT TO BE LIT TO SCHEDULE A PUMP OUT.
o Marine toilets are flushed by manually pumping effluent out using the built-
in hand pump – see the procedure below for details.
• Wash basin
o The wash basin empties overboard. If it does not drain verify that the
seacock for the drain is open. The seacock is in the storage area located
on the lower forward wall of the lavatory.
o Water for the wash basin comes from the on-board freshwater tanks and
is pressurized by a pump. If there is no water when you turn on the tap
verify that the Pressure Water switch is ON on the 12VDC panel above
the navigation station. If the switch is on verify that the tanks have water in
the and that the valves at the tanks are open.
• Shower
o The shower is made of 2 parts
▪ The shower head is a pull out from the wash basin.
▪ The drain empties water into the bilge. Normally the bilge pump will
drain the bilge automatically. If it does not you must turn on the
bilge pump manually. After the bilge is drained reset the switch to
automatic.
