    Flushing Technology

    • AquaPiston canister allows water to flow into the bowl from all sides (360 degrees), increasing the power and effectiveness of the flush
    • AquaPiston canister flush valve optimizes flush performance and resists warping and deterioration
    • 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
    • Single-flush gravity uses the force of gravity and a precision-engineered tank, bowl, and trapway to create a strong siphon during flushing
