Manual Flush Head Systems

The marine head installed on your yacht uses seawater
to flush waste from the toilet.
• Before using either head make sure the appropriate
seacock is open. The intake seacocks should be left
CLOSED whenever the yacht is left unattended
• The raw water intake seacock for the forward head
can be accessed by lifting the forward salon steps.
The raw water intake seacock for the aft head can be
accessed from the floor hatch located below the
television cabinet in the aft berth.
Operating the manual flush marine head:
1. OPEN the head's raw water intake valve (seacock).
2. Before using the head, pump enough water into the
bowl to wet the sides.
3. After use, pump until the bowl is thoroughly
cleaned. Pump a few more times to clean the lines.
If excess waste causes the water to rise in the bowl,
stop pumping until the water recedes.
If you are unable to pump water into the bowl, the
probable cause is debris in the pump diaphragm. To
remedy this, shut off the raw water intake valve (sea-
cock) and dismantle the pump. The pump is generally
held together with six screws (the design is simple and
the problem will be obvious when the pump body is
split open). To winterize the head, shut off the intake
seacock and pump until the bowl is dry. Remove the
drain plug in the base and pump again to remove all of
the water. DO NOT fill the bowl with antifreeze.
Vacuflush Head Systems
(Option)
The (optional) vacuflush system
includes a vacuum generator for
each toilet and filter on your
waste tank vent hose. The vacu-
flush system uses freshwater
(refer to the fresh water section in
this manual) and the vacuum gen-
erators to flush waste from the
toilet directly into the holding
tank. Refer to the manufacturer's
operation and maintenance man-
ual (included in your yacht's
owner's pack).
