The canister flush valve's 3:2 ratio optimizes flush performance and resists warping and deterioration, while its durable design features 90% less exposed seal material than a standard 3-inch flapper flush valve, guaranteeing leak-free performance. The light-touch canister requires lower activation force than a flapper, and once activated, allows water to flow into the bowl from all sides (360 degrees), increasing each flush's power and effectiveness.WaterSense Certified Product: To help make a difference on a global scale and to further its role as an industry leader in eco-performance practices, Kohler has established partnerships with a number of environmental organizations, including WaterSense. Many Kohler faucets and toilets are equipped with low-flow technology - they use less water, while continuing to meet superior performance standards.Product Specifications:Overall Height: 13-1/2" (measured from bottom to top of tank)Overall Depth: 8-3/16" (measured from back to front of tank)Overall Width: 17-7/8" (measured from rightmost to leftmost edge of tank)Flow Rate: 1.28 GPF (gallons per flush)Variations:K-4431: This modelK-3551: This model with bowl (complete toilet fixture) Standard Toilet Tanks Black Black
