Pre-rinse spray valves—often used in commercial and institutional kitchens—are designed to remove food waste from dishes prior to dishwashing. By switching to a high-efficiency pre-rinse spray valve, a commercial or institutional kitchen can save more than $110 annually in energy and water costs. After having a label for efficient high-performing pre-rinse spray valves for several years, WaterSense has successfully transformed the marketplace for commercial kitchen pre-rinse spray valves.
