Don't settle for a wimpy flusher. Maximum Performance testing (MaP) gauges a toilet's ability to get the job done with just one push of the handle. Look for a loo with a MaP score of 500 or higher; this group includes many WaterSense-rated toilets, high-efficiency models that use as little as half of the 1.6-gallon-per-flush legal limit.
