AquaPiston
Single-flush gravity uses the force of gravity and a precision-engineered tank, bowl, and trapway to create a strong siphon during flushing. The AquaPiston canister allows water to flow into the bowl from all sides (360 degrees), increasing the power and effectiveness of the flush. The flush valve’s 3:2 ratio harnesses the natural force of gravity and optimizes flush performance. The durable canister design has 90% less exposed seal material than a 3-inch flapper for leak-free performance, and the light-touch canister flush requires a lower actuation force than a flapper.
