High-efficiency toilet

A toilet that provides at least 20 percent water savings over the federal standard of 1.6 gpf (gallons per flush), and still meets the most rigorous standards for flush performance. HETs include pressure-assist toilets that use as little as 1.0 gpf, gravity-flush toilets that consume 1.28 gpf, and dual-flush toilets that offer two different flush volumes.
