At Greenbuild: Flapperless HETs
February 1, 2010

Employing the only gravity-flush design that controls water flow with the use of patented tipping-bucket technology, Niagara’s EcoLogic Flapperless toilets eliminate the need for rubber flappers and flexible seals in the tank, a leading cause of leaks and callbacks for plumbing professionals. These models take this technology to the next level with the use of only 1.28 gpf, qualifying them as high-efficiency toilets that meet EPA WaterSense criteria and HET rebate standards.
