HEAD SYSTEM

HEAD
It is always good seamanship to close the intake and discharge
seacock (if installed) for the head when leaving the vessel. Also,
be certain, while sailing, that the flush control valve or lever on
the head is not left in the flush position so as to prevent the head
from filling with water which will spill as the boat heels.
Y VALVE - Opt.
If your vessel is operated outside the territorial waters of the D.S.,
the "Y" valve may be shifted to pump toilet effluence directly over-
board. Note that this practice is illegal in U.S. waters and will
result in a substantial fine. Some waters prohibit the existence of a
"Y" valve, so the device should be removed for navigation in these waters.
Conformance with sanitation laws is an owner responsibility. Please
see the diagram showing the direction of effluent flow to be sure the
handle on the "Y" valve is properly positioned (see p. 7.3-1)
HOLDING TANK
Your vessel is equipped with a holding tank for retention of sewage.
The holding tank, like the water tank, is also made from polyethylene
and is connected to the following hoses: (a) Waste Discharge Hose from
the Head; (b) Pump-out Hose leading to deck plate; (c) Vent hose. This tank
vents overboard.
Sea water is used to flush the head, and the sea water and effluent
are pumped into the holding tank by pumping the toilet. A deck fitting
is provided through which the holding tank may be evacuated by a
shoreside pump-out station.
With the standard holding tank, it is not necessary to "prarharge" the tank
by adding water before using the system. Be certain that the pump on
