Head Waste System
WHAT IS THE LAW?
Congress enacted the Clean Water Act of 1972 (amended in 1987). This law
addresses a wide spectrum of water pollution problems, including marine sewage from boats in navigable
U.S. waters including coastal waters up to three miles offshore. The law further provides for "no
discharge" by boats operated in enclosed lakes and reservoirs or in rivers not capable of interstate
navigation. States may apply to the EPA to have certain other waters declared "no discharge zones" if
discharge of treated sewage would be harmful. In short, boats with installed toilets must have an
operable Coast Guard approved Marine Sanitation Device (MSD) designed to either hold sewage for
pump out ashore or for discharge in the ocean beyond the three mile limit, or to treat the sewage to
Federal standards prior to discharge.
All boats built since 1977 with installed toilets must have an operable approved type I, II or III MSD.
Since 1980, all boats (including those built before 1977) with installed toilets must have an operable MSD.
Both the U.S. Coast Guard and the Natural Resources Police can enforce MSD requirements.
Check with your local authorities, Coast Guard, local marina or your dealer for the rules and/or laws that
may apply specifically in your area.
Dockside Discharge Waste Outlet
This stainless steel fitting labeled “waste” is located amidships on the port gunwale. Twist the cap to
open the fitting and connect to your marina’s dockside service facilities.
Vacuum Flush Head System
Your Pro-Line is equipped with a VacuFlush head system and dockside discharge. The overboard
discharge system is available as an optional installation.
Note: There must be fresh water in the fresh water holding tank in order for the head
macerator pump to operate and properly flush the system. Operating the pump with an
empty tank could cause serious damage to the pump.
To operate or test the VacuFlush head system, make sure that your fresh water tank is full of water.
Make sure that the DC main, fresh water, and head switches on the AC/DC panel are all in the on
position. To flush the VacuFlush head system, use your foot to depress the pedal at the base of the
head. This action will pump fresh water into the stool, empty the head and transfer all waste into the
waste tank. When you release the pedal, water will stop entering the stool and the flushing action will
cease.
Dockside Discharge – When at a marina that offers
dockside discharge, the marina will provide the facilities
needed to perform this operation. You will not need to use
the Tank Watch system (optional equipment with overboard
discharge). The stainless steel fitting labeled waste is
located amidships on the port gunwale. Twist the cap to
open the fitting and insert the hose provided by the marina
into the dockside discharge waste outlet to connect to your
marina’s dockside discharge service facilities. Follow the
instructions provided by the marina to operate their
equipment.
