The hybrid retrofit urinal from Sloan Valve Co. features Falcon WaterFree Technology. The urinal conserves nearly 100 percent of the water and can upgrade most existing flush urinals to high-performance hybrid technology. The urinals do not require water after each use and are not dependent on users to flush. Instead, they utilize a flush system that automatically performs a full gallon flush through the housing and pipe system every 72 hours (about 102 gallons a year regardless of the users). The timed volume of water flushing through the system prevents hard scale buildup, while earning maximum LEED credits. 800/982-5839; www.sloan.com.
