AMTC introduces the HYBRIDFLUSH side-mount sensor flush valve for urinals and water closets. The flush valve is offered as a complete flushometer and as a retrofit kit that easily adapts to most existing flushometers, AMTC notes. It is an all-metal unit powered by four C-cell batteries. It features quiet operation, and electrical and mechanical pushbutton (that keeps working when batteries are drained), and includes unique water-saving options, the company adds. AMTC Corp.
