Overview

This WaterSense(R)-labeled high-efficiency toilet combines water conservation with the versatile style of the Cimarron collection. A 1.28-gallon flush provides significant water savings of up to 16,500 gallons per year, compared to a 3.5-gallon toilet, without sacrificing performance. This toilet features innovative AquaPiston technology, a patented flush engine that delivers a fast, powerful, and virtually plug-free flush. An elongated bowl, positioned at the height of a standard chair, offers comfort and ease of use. An insulating tank liner helps prevent condensation on the outside of the tank.

• AquaPiston canister allows water to flow into the bowl from all sides (360 degrees), increasing the power and effectiveness of the flush.
• Flush valve's 3:2 ratio harnesses the natural force of gravity and optimizes flush performance.
