How The VacuFlush® System Operates:

VacuFlush systems operate with fresh water, eliminating the mal odors and calcification build-up caused by lake and seawater organisms that die in the lines. It only uses an average of a pint of water per flush... Less water during the flush cycle in a VacuFlush system allows for up to four times more holding tank capacity than other types of systems.

Vacuum is the most efficient way to evacuate the lines of waste. This cuts down the chances of permeation cause by sewage sitting in your lines, more common with other systems.

All this performance with adult size seats and very low power consumption from 3 – 7 amps. A boat with a VacuFlush system enhances the resale due to its long running reputation and reliability.

1. Vacuum is maintained in the system at all times. Before use, the water level in the bowl can be raised by simply lifting the flush lever.

2. When the toilet is flushed by pushing down on the foot lever, the vacuum energy stored in the system is released.
The change of pressure in the vacuum tank causes the integral pressure switch to activate the vacuum pump. The bowl is instantly cleared and the waste is moved through the vacuum pump, at 7 feet per second, and pushed to the holding tank.

3. After the flush lever is released, creating a vacuum tight seal at the toilet bowl, the vacuum pump continues to run until the vacuum level is recharged in the system. Recharging the vacuum takes about one minute.
