The head macerator pump, “Y” valve, holding tank and brass seacock are all installed below the sink area in the
head.
The head macerator pump is used in the overboard discharge operation. The “Y” valve must be in the correct
position to direct the waste either overboard or to your marina’s dockside discharge facilities. Before utilizing the
dockside or overboard discharge functions, make certain that the “Y” valve is in the correct position.
Before attempting to flush the toilet, make sure that
the seacock is in the open position. The seacock is
open when the yellow lever is in the full upright
position. When the lever is in the horizontal
position, the seacock is closed.
The “Y” valve is installed on the port side of the
pump, just outside the view of the photo to the
right. It allows you to switch back and forth
between dockside and overboard discharge. The
photos below show the 2 positions for the “Y” valve
(i.e., dockside discharge vs. overboard discharge).

Dockside Discharge - When at a marina that offers dockside discharge, the marina will provide the external
facilities needed to perform the dockside discharge operation. To operate the dockside discharge, turn the “Y”
valve to the dockside discharge position as shown here.
The “Y” valve for the Electric Head as shown here is set to use dockside discharge. Follow the arrows. Waste is
going from the holding tank, to the “Y” valve and then upward to the waste outlet.
The waste outlet is a stainless steel fitting, labeled waste. It is located
amidships on the starboard gunwale. Twist the waste outlet cap to open the
fitting and insert the hose provided by the marina into the waste outlet to
connect to your marina’s dockside service facilities. Follow the instructions
provided by the marina to operate their equipment.
Warning: Waste in the holding tank can form methane, an
explosive gas. Use suitable precautions when any
maintenance is done to the sanitary system.
Overboard Discharge - To operate the overboard discharge, turn the “Y”
valve to the overboard discharge position. The “Y” valve for the Electric Head
as shown here is set to use overboard discharge. Follow the arrows. Waste
is going from the holding tank, to the “Y” valve and then to the electric head
pump. Then, go into the head area and flip the macerator switch to the on
position.
Before using the overboard discharge system, be sure to check with your
local authorities, U.S. Coast Guard, local marina or your dealer for the rules
and/or laws that may apply specifically in your area. Before operating the
electric head system, refer to the manual in your owner's packet supplied by
the electric head manufacturer for specific operating instructions.
Warning: Waste in the holding tank can form methane, an explosive gas. Use suitable
precautions when any maintenance is done to the sanitary system.
