This WaterSense-labeled tank combines water efficiency with the versatile style of the cimarron collection. A 1.28 gpf 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.

• Supply line not included
• Combines with the K-4309 bowl to create a complete K-3609 Cimarron toilet
