350 SPORT YACHT

Shower Sump Below Forward Aft Cabin Berth

7.4 Cabin Drains

The galley sink, head sink, and refrigerator are
drained by gravity to thru-hull fittings in the star-
board hull side.

The shower and air conditioner condensation pan
are drained by a sump pump system. An auto-
matic float switch in the sump controls the pump.
The sump pump is protected by the shower sump
circuit breaker in the battery switch panel. The
sump system is activated whenever the batteries
are connected to ensure the shower and air con-
ditioner will drain properly whenever they are is
used. After showering, let the cold water flow for
a period of time to flush the drainage system of
soap residue.

The sump system is located below the forward
berth in the aft cabin and accessed by removing
the mattress and opening the access hatch. The
sump has a removable lid to allow the system to
be inspected and serviced. It is essential that
the sump system be inspected periodically and
any accumulated debris removed. Manually acti-
vate the system to verify operation.

Optional Grey Water System

If your boat is equipped with this option, all sink
drains and the head shower are drained by the
shower sump system which pumps the waste wa-
ter to the waste/grey water holding tank. The air
conditioner condensation pan is connected to a
separate sump pump system that pumps the ac-
cumulated condensation overboard thru a fitting
in the hull side. Both sump systems are controlled
by an automatic float switch in the sump and are
protected by individual circuit breakers in the bat-
tery switch panel. They are activated whenever
the house battery switch is on and are located
below the forward berth in the aft cabin.

The fluid level in the waste/grey water holding
tank is monitored by the “Tank Watch Monitor” in
the head compartment. When the holding tank is
full, it must be pumped out by an approved waste
dumping station. You should monitor the waste
level carefully and not allow the tank to become
full. The toilet will not flush when the tank is full
and an overfilled holding tank will force waste into
the vent filter. This will clog the filter, prevent
the sinks from draining and could cause damage
to the holding tank. It will also cause unpleasant
odors in the cabin.

Note: The overboard macerator discharge

pump option for the waste holding tank
is not available with the grey water sys-
tem.

7.5 Drainage System Maintenance

It is essential that the following items be done
periodically to maintain proper drainage of your
boat:

•

Clean the cockpit and bridge deck drain rails
with a hose to remove debris that can block
water drainage.

•

Clean the bilge pump strainers of debris and
check the bilge for foreign material that can
cause the automatic switch to malfunction.

•

Frequently test the automatic bilge pump
switches for proper operation. This is
accomplished by turning the knob on the float
switch until the pump is activated. You can
also use a garden hose to raise the water level
in the bilge high enough to activate the pump.

•

Flush all gravity drains with fresh water to keep
them clean and free flowing.

•

Flush the drain in the air conditioning
condensation pan with fresh water periodically
to remove mold and debris that can accumulate
and block drainage to the sump system.
