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 16500 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 virtually plug-free flush. Pair this tank with the K-4309 bowl for a complete toilet.

  • Combines with the K-4309 bowl to create a complete K-3609 Cimarron toilet
  • 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 Inch 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 guide lines including using at least 20 percent less water than 1.6 gal toilets
  • Eligible for consumer rebates in some municipalities
