Available in a two-piece unit as well as a high-efficiency toilet, the Champion 4 flushing system eliminates clogging and noisy flushes, the maker says. Its 4-inch opening between the tank and bowl pushes water into the bowl three times faster than standard valves, the makers says, and a bigger trapway can move a 70 percent larger mass than a standard product. The system also includes EverClean, a fired-in antimicrobial surface that repels dirt and resists bacteria growth on the exposed surfaces of the toilet. 800.899.2614.www.americanstandard-us.com.
