How does a Saniflo macerating upflush toilet work?
An upflush toilet has been engineered to solve common bathroom installation problems. While their interiors are hardworking machinery, their exteriors are a fashionable complement to any decor. Their main difference from standard fixtures is the discharge system, whose key components are a macerator/pump and a small-diameter pipe. The powerful macerator has a rotating blade that shreds and grinds solid material like human waste and toilet paper. When mixed with flushing water, solid material changes to a fine slurry which moves easily through a narrow pipe upward. The macerator/pump is sealed for life and requires NO maintenance! And no waste sits inside the unit like other brands.
A quiet electric-powered pump moves the fine slurry upward under pressure. The small-diameter discharge pipe (as small as 3/4" across), solves many structural problems as it can be run virtually anywhere. The fine slurry moves easily through this pipe to the normal sewage system, septic tank or holding tank.

Do macerating systems, gray water pumps and fixtures need to be vented?
All macerators and gray water pumps have been designed with a vent connection on the lid. All plumbing codes require connection to a vent system. Please note that the vent system should be a two-way air vent. The use of mechanical vents, air admittance valves or similar devices are not permitted as these are considered one-way vent systems. The Sanicompact and Sanistar units are “forced mains” and they do not need to be vented.
How much water does the system use?
All models in the Saniflo line are low consumption type water closets. The Sanitop/Saniplus/Saniaccess3/Sanibest Pro uses 1.28 gallons (4.8 liters) of water per flush. The Sanistar and the Sanicompact48 are dual flush systems as they use 1.28 gpf (4.8 lpf) and 1 gpf (3.8 lpf). This compares very favorably with older style water closets that may use up to 3.5 gallons (30 liters) of water per flush.
What is the discharge capacity?
Depending upon the discharge installation, the Saniplus/Sanibest Pro/Saniaccess3 can pump up to 27 gallons
per minute and the Sanivite can pump up to 18 gallons per minute. The Sanicompact/Sanistar cannot pump more than 1.28 gallons at a time as it is an electrically timed system.
