Sloan Valve Co.
DFSM/SFSM flush valve retrofit units are side-mounted and can be installed in areas without an electrical hook-up. Sensor activation and diaphragm technology allow for retrofitting of manual flush units with either automatic flushing or manual dual flush (water closet only) or single-flush (water closets or urinals) options. Dual flush uses 1.6 gpm; single flush uses 1.1 gpm. Manual flush button offers mechanical override function to allow flushing when batteries need to be replaced. Indicator lights show when batteries need replacing.
