Technology
•
Single-flush gravity uses the force of gravity and a precisionengineered tank, bowl, and trapway to create a strong siphon
during flushing.
•
AquaPiston® canister allows water to flow out of the tank from
all sides (360°), 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" flapper for leak-free performance.
•
Light-touch canister flush requires a lower actuation force
than a flapper.
