Gerber expands the Avalanche toilet family with the Avalanche 1.28 LS. Now available in one and two piece options, the Avalanche 1.28 uses only 1.28 gallons of water per flush (gpf) versus the industry standard 1.6 model. Engineered with a 3-in. flush valve for quick evacuation, all the Avalanche toilets have an effective flushing process which clears the bowl faster and more efficiently. The Avalanche 1.28 LS includes a reliable Fluidmaster Leak Sensory Pro Fill valve that eliminates toilet run-on when not in use, thereby saving water.
