The lineup of Aqua Mizer toilet flush systems was featured in the American Society of Plumbing Engineers’ 2012 Innovative Product Showcase for the water-saving and maintenance-reducing characteristics each was designed to deliver. Tests prove that Aqua Mizer systems can decrease flush volumes by as much as 52 percent on standard three-gallon units and 26 percent on low-flow units. New designs to the lineup include a flat flapper valve that increases the velocity of water, a built-in filter that ensures consistent high-performance flushing and a fill valve diaphragm housing constructed of acetal to eliminate corrosion and clogging.
