TYPICAL VACUUM STYLE HEAD SYSTEM
Vacuum Toilet- The Vacufl ush® toilet operates in a
different way from other marine toilets. The system
uses around 16 ounces per fl ush plus a simple vacu-
um to complete each fl ush which is a substantial wa-
ter savings over other systems. The toilet is connect-
ed to a pressurized fresh water supply. Fresh water is
the key to an odor-free bathroom compartment. Se-
lected other systems use intake water from wherever
the vessel is sitting which may carry an odor. The Va-
cufl ush® units are equipped with a special vacuum
breaker which prevents the possible contamination
of the potable water system.
Vacuum Tank- This tank stores the vacuum energy
used in the system. When a switch senses a drop in
the vacuum it automatically energizes the pump to
upgrade the vacuum. This process in on-going be-
tween fl ushes.
Vacuum Pump- This unique bellows style pump is
designed to handle solids without a problem. It uses
two duckbill valves on each side of the pump cham-
ber to prevent backfkow of waste and vacuum.
Vacuum Generator- This unit houses the vacuum
pump and tank in one unit. It is compact over other
units.
Holding Tank- Unit features polyethylene compo-
sition 50% thicker than other holding tanks. A de-
odorant additive is required to keep the holding tank
odor-free.
In-Line Vent Filter- The vent fi lter is located above
the holding tank. It helps keep the boat’s waste vent
system sanitized. Heavier-than-air malodors accumu-
late in the holding tank. The fi lter uses special charged
fi lter media to remove the odors before they become
offensive. Replace the fi lter each year. Contact your
Regal dealer.
Fresh Water and Waste Monitor- Your vessel uses a
fresh water and waste monitor panel to display the
levels in each system. See the information earlier in
this chapter.
Overboard Discharge Pump- An optional overboard
discharge pump vacates waste through the deck waste
fi tting or a seacock (only used beyond the 3 mile limit
in the USA).
