STERLING®TOILETS
WITH DUAL FORCE™TECHNOLOGY
Dual Force technology by Sterling provides an outstanding combination of water
conservation and exceptional performance. Operated by a user-friendly, two-button
actuator integrated into the tank lid, STERLING toilets with Dual Force technology flush
either 1.6 gallons or .8 gallon. The .8 gallon flush option, for liquid and light waste, can
save a household of four up to 25,000* gallons of water per year.
Equally impressive, the 1.6-gallon setting, assisted by the
toilet’s flapperless valve and large trapway, consistently
removes bulk waste with just one flush, eliminating the
need for wasteful, repetitive flushing. In addition, 100% of
the water passes through the rim, keeping the bowl clean
with its siphonic washdown system.
*25,000 gallons versus a 3.5 gallon toilet, or 6,000 gallons versus a 1.6 gallon toilet.
