This WaterSense(R)-labeled tank combines water efficiency 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 tank features innovative AquaPiston technology, a patented flush engine that delivers a fast, powerful, and virtually plug-free flush. Pair this tank with the K-4309 bowl for a complete toilet.

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

Durable canister design has 90% less exposed seal material than a 3-inch flapper, for leak-free performance

Light-touch canister flush requires a lower actuation force than a flapper

DryLock(TM) System saves installation time and helps prevent water leakage

WaterSense(R) toilets meet strict EPA flushing guidelines, including using at least 20 percent less water than 1.6-gallon toilets
