flush) and is controlled by DC electrical
power. Each toilet is equipped with an
integral vacuum breaker that prevents a
backflow of contaminated water into the
potable water supply. Vacuum energy,
supplied by the Vacuum Pump, is stored in
a Vacuum Tank and is monitored to main-
tain a certain level. The Vacuum Pump is
controlled by an electrical breaker switch,
located on the AC/DC Electrical Panel.
Refer to the Electrical Pages of this sec-
tion in this Owners Manual for the location
of the switch. As the toilet is flushed,
vacuum energy is depleted and the
Vacuum Pump will automatically activate
to restore the required level. The Vacuum
Pump will operate for approximately 30 to
90 seconds until the system reaches the
required operating vacuum level. Toilet
waste, both liquid and solid, is removed by
the vacuum energy and water combination
to a Waste Tank having a capacity of sixty
(60) gallons. The Mechanical Layout in the
Schematics Section of this Owners
manual shows the location of the Tank.
This waste is stored in the Waste Tank
until pumped out at a proper facility. The
photo below shows the waste tank. It is
located under the forward stateroom.
MARINE SANITATION SYSTEM
All vessels with fixed toilets that are oper-
ated on the waterways of the United
States and some foreign countries are
required to be equipped with an operable
Marine Sanitation Device(MSD). The
Marine Sanitation System in your 43MY
is a Waste Tank system, defined by the
United States Coast Guard as a Type III
System. Type III Systems permit operation
of the toilet without the direct discharge of
untreated waste after every flush. Type III
Systems can be discharged at marina
dockside pump-out stations or, if in coastal
waters, at least three(3) miles offshore.
NOTE: Overboard discharge capability
must remain inoperative while within the 3
mile limit. This is accomplished by closing
the macerator discharge thru-hull valve.
Refer to the Mechanical Layout Schematic
in the Schematic Section of this owners
manual for the location of the valve.
Your 43MY is equipped with one of the
following Marine Sanitation Systems,
depending on the option you chose from
your Silverton dealer at the time of pur-
chase:
• SeaLand Vacuflush Toilet
• Jabsco Quiet-Flush Electric Toilet
(Fresh Water)
• Jabsco Electric Toilet
(Raw Water)
SeaLand Vacuflush Toilet
This system is operated by vacuum,
combined with a small quantity of water
supplied by the pressurized fresh water
system (approximately one(1) pint per
