The SLOAN 3307133 is a red piston assembly designed for use in Sloan GEM2 series urinal flushometers rated at 0.5 gallons per flush (GPF). The piston assembly controls the flow and volume of water delivered during each flush cycle, making it a critical internal component of the valve. At 0.5 GPF, this assembly meets low-consumption flush requirements common in commercial restroom applications. It is color-coded red for easy identification during service. Licensed plumbers and commercial restroom maintenance technicians install and replace this part during routine valve servicing or when flush volume requires adjustment.
This piston assembly is intended for commercial and institutional restroom environments where Sloan GEM2 flushometer valves are installed on urinal fixtures. It is the appropriate replacement when the existing piston is worn, damaged, or when converting a flushometer to a 0.5 GPF flush rate. The red color coding distinguishes the 0.5 GPF piston from other flow-rate assemblies used in the same valve platform, simplifying identification on the job.
Designed for use with the Sloan GEM2 series urinal flushometer valves at 0.5 GPF.
Installation should be performed by a licensed plumber. Shut off the water supply to the flushometer and relieve line pressure before disassembling the valve. Follow standard plumbing codes applicable to your jurisdiction when servicing commercial flushometer valves. Do not force or overtighten internal valve components during reassembly.
