Grey Water System
When equipped with a Grey Water System
you will notice that the sinks and shower
drain into the Sump and are pumped to the
Grey Water tank.
From here this tank is emptied at dockside
with the procedure described on page 14.
When using the overboard discharge
procedure (where legal) there is a "Y"
valve that must be switched between the
WASTE tank and GREY WATER tank. The
discharge pump, valve and switch operate
the same in either case.
Note: It is against the law to discharge
waste overboard in many areas of
the United States.
It is your responsibility to make sure
that you are in compliance with all
applicable federal, state and local laws
when using your boat's overboard
discharge system.
People who discharge waste overboard
in restricted areas are subject to
significant penalties.
