Saniflo's Sanibest Pro macerating toilet system uses a smaller amount of water than conventional toilets: 1.28 gpf vs. 1.6 gpf, but with no sacrifice in flushing power. It is also eligible for LEED certification, and recognized as water-saving by the EPA’s WaterSense program. The Sanibest Pro is used to install a complete bathroom up to 25 feet below the sewer line or up to 150-feet away from the soil stack. This one-horsepower pump system contains three inlets to handle drainage for a full bathroom. Aside from the 4-inch inlet for toilet connection, a 2-inch inlet on either side of the unit easily connects to other sanitary fixtures — a sink, a bathtub or a shower — to drain greywater.
