AquaPiston canister allows water to flow out of the tank 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
