Zurn’s low-flow EcoVantage 1.1-gpf ZTR sensor wall bowl system requires 31% less water per flush. The low-flow performance also is 20% better than the LEED baseline water savings for commercial buildings. The system includes the wall bowl and the 1.1-gpf top-mount sensor flush valve or the 1.1-gpf top-mount sensor flush valve with long-life battery. It can be used in combination with the reduced splash-back Omni-Flo urinal, which includes the 0.5-gpf sensor-activated, battery-operated piston flush valve with long-life batteries.
