Aquia Dual-Flush Toilet from Toto
Toto, a leading toilet manufacturer whose toilets have consistently been among the best in terms of flush performance, introduced to North America the Aquia™ Dual-Max™ dual-flush toilet in May 2005. While this toilet has been available elsewhere for five or six years and is the most popular toilet in Thailand, where it is manufactured, according to Gunnar Baldwin of Toto, this marks the company’s dual-flush entry in North America. The Aquia uses 1.6 gallons (6.0 liters) of water in the high-flush mode and 0.9 gallons (3.4 liters) in the low-flush mode. The low-volume flush is designed for use with liquid wastes (and paper), while the standard flush is for solid wastes. 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. ...
