Technology
•
Single-flush gravity uses the force of gravity and a
precision-engineered tank, bowl, and trapway to create a strong
siphon during flushing.
•
AquaPiston canister allows water to flow into the bowl 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.
•
Light-touch canister flush requires a lower actuation force than
a flapper.
