create strong siphon during flushing.
•
AquaPiston® canister optimizes the flow out of the tank,
harnessing gravity and the natural powerful reducing cascade
of water to increase the power and effectiveness of the flush.
•
Easy-to-flush canister design requires less force to actuate
than a 3" (76 mm) flapper, and has 90% less exposed seal
material which resists conditions that cause wear, tear,
shrinkage and swelling.
