Performance-verified, low-flow pre-rinse spray valves use less water to rinse dishes than normal restaurant spray valves. Low flow valves restrict the amount of water and, depending on design, exhibit comparable performance.
Normal pre-rinse spray valves use about 3 gallons of water per minute (gpm). A low flow pre-rinse spray valve uses up to 1.6 gpm, about a 50 percent reduction in water use. In addition to water savings, water heating and sewer charges are reduced. If the valve is used 3 hours per day annually, the possible savings can be in the hundreds of dollars per year.
