Aquia Dual-Flush Toilet from Toto

Like most other Toto toilets, the Aquia is a

wash-down, gravity-flush toilet. The bowl has steep sides, and 100% of the flush water enters through the toilet bowl rim and exits through a larger-than-average, 2 5⁄8" (67 mm) trapway. By contrast, most U.S. toilets rely on a siphon-jet technology in which much of the flush water enters through the side of the bowl, creating a swirling, siphonic action that pulls—rather than pushes—water and wastes out of the bowl.
