No maintenance is required on
y
our macerator pump
.
Helpful Hint: Should the macerator pump become clogged, you
can manually rotate the internal grinder wheels by removing
the small plastic cap on the back of the macerator pump. This
encloses the screw which is attached to the grinding wheels and
by inserting a flat screwdriver, you can rotate the wheels and
possibly remove any debris clogging the pump.

Important: U.S. Coast Guard regulations require that boats
have a sanitation system on board to control pollution. Waste
is to be stored in a holding tank or other device so it can be
properly disposed of at a shore facility. Discharging this waste
overboard in U.S. lakes, rivers, bays, and sounds and within 3
miles of shore in international waters is prohibited. Check with
the Coast Guard regarding regulations in your area.
