Product Overview

This WaterSense-labeled tank combines water efficiency with the versatile style of the Cimarron collection. A 1.28 gal. flush provides significant water savings of up to 16,500 gal. per year, compared to a 3.5 gal. toilet, without sacrificing performance. This tank features innovative AquaPiston technology, a patented flush engine, that delivers a fast, powerful, and plug-free flush. An insulating liner helps prevent condensation on the outside of the tank. Pair this tank with the K-4309 bowl for a complete toilet.
  • 1.28 gallons per flush (gpf)
  • Standard left-hand Polished Chrome trip lever included
  • Insuliner tank liner minimizes condensation on the tank when exposed to high humidity
  • Supply line not included
  • Coordinates with other products in the Cimarron collection
  • Single-flush gravity uses the force of gravity and a precision-engineered tank to create a strong siphon during flushing
  • 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 in. flapper, for leak-free performance
  • Light-touch canister flush requires a lower actuation force than a flapper
  • DryLock System saves installation time and helps prevent water leakage
  • WaterSense toilets meet strict EPA flushing guidelines, including using at least 20 percent less water than 1.6-gallon toilets
