Optional Vacuflush Head System

The optional vacuflush head system uses freshwater and a vacuum generator to flush waste from the toilet into the
holding tank. If your yacht is equipped with a Y-valve (located in the utility room), waste can be routed into the hold-
ing tank or, where regulations permit, pumped directly overboard. The holding tank is plumbed to a waste fitting on
the deck for dockside pump-out and to a macerator pump for pumping waste overboard (where regulations permit).
The macerator switch is located at the helm station.
