VacuFlush toilets increase holding tank capacity.
VacuFlush toilets operate with a pump-generated vacuum which uses only about a pint of water per flush. Typical marine toilets use a gallon or more per flush, filling a holding tank more than four times faster than with VacuFlush.

VacuFlush toilets use less electricity to flush.
Our system draws a mere 4-6 amps, while competitive systems draw up to 60 amps.

All S-series and T-series pumps are now converted to the new W motor. When using the W motor as a replacement for older motors, the bellows must be replaced. If a new W motor is used with the older bellows design, the diameter of the old bellows plays a big factor in producing a pump knocking noise. To avoid this, it is necessary to use the complete W motor kit for all S and Q motor replacements.

The new whisper W motor kit includes: a W motor, eccentric, o-rings, shoulder bolt, bellows and two bellows clamps. The W motor kit numbers are:
12-volt: 385311423
24-volt: 385311424
