Waste and Sanitation Systems
10.2
Basically, all pumps are in some way associated with the
waste/sanitation system, but this section will only focus
on pumps that are directly associated with the process of
pumping waste overboard. The supply function of these
pumps are discussed in other sections.
Please refer to Figure 10.17 for the bilge/sump pump and
drain layouts as reference to the subsequent discussions.
Please reference the DC Electric System chapter of this
manual for details regarding control and circuit protection
of the waste related pumps.
10.2.1 Bilge Pump
The safety of those on board your boat is a primary
objective. Therefore, we strongly encourage you review
all information contained in this manual, as well as the
manufacturer’s OEM manuals concerning all systems on
your boat. Specifically, the bilge pump system will be one
that is crucial to fully understand. These pumps have the
critical function of removing water from the bilges of your
boat. They must be kept clean and functional to ensure
they complete their task.
The main bilge pump (Fig. 10.2) is installed in the main
salon and accessed through the main bilge floor panel. It
is rated at 12 1/2 GPM pumping capacity and is the first
responder in the event of water collection.
Figure 10.2
10.2.1.1 Main Bilge Pump Operations
The main bilge pump is a “smart” pump; its electronic
sensor activates the pump when water is present. In
addtion, the pump can be manually activated by flipping
and holding the toggle switch on the DC panel to the right
until the pump out is complete. The toggle will spring
back upon release. (See the DC Electric chapter in this
manual for additional details on switch controls.) The
pump will discharge waste through a starboard thru-hull.
NOTE: Power to the DC panel is not required in order to manu-
ally operate your bilge pumps.
10.2.1.2 Maintenance on Bilge Pump
No maintenance is required beyond ensuring that the
float switches are operational and pump intakes are
debris free.
10.2.2 Emergency High Water Alarm
The high water alarm will sound if your boat is taking on
water sufficient to overwhelm the ability of the main bilge
pump to properly discharge. Should the water level rise
above the high water mark, you will hear the high water
alarm sounding from the Safety Panel, located on the
forward starboard cockpit, together with a solid red light
displayed (Fig. 10.3). This alarm means high water exists
in the bilges and it is time to take action.
For reference on possible courses of action, we recom-
mend reading (prior to your initial launch) Chapman’s
Piloting, Seamanship and Boat Handling for recommen-
dations on responding to a high water situation. If you
do not have a copy of this book, we strongly encourage
purchasing a copy and keeping it handy; it is full of useful
safety and navigational information.
The high water mark is determined by the placement of
the high water float switch (Fig. 10.2) located in the main
bilge and accessed through the forward center floor panel
in the main cabin.
The alarm system can be periodically tested using the
push button switch located on the Fuel/Safety Panel.
Pressing the TEST button will activate the audible alarm
and light display to verify proper operation. Release the
button to end the test.
