Sloan Valve Co.
The Dual-Flush Side Mount is battery-powered and uses Smart Sense Technology™ that automatically initiates a 1.1 gallons per flush (gpf) flush when the user is in range for less than 60 seconds. If users prefer to flush manually, they can choose the appropriate flush cycle by pushing one of two buttons: the larger, black button for a standard 1.6 gpf flush cycle or the smaller, green button for removing liquid waste with the 1.1 gpf cycle.
