Sloan 4328466 Shower Head Piston Replacement Kit 2.5 Gpm

Product Description

The SLOAN 4328466 is a piston replacement kit for Act-O-Matic showerheads rated at 2.5 gallons per minute (GPM). The piston is the internal metering component that controls water flow and shutoff timing in Act-O-Matic self-closing shower valves. When the piston wears or fails, flow control and automatic shutoff performance degrade. This kit restores correct function without replacing the entire showerhead assembly. Installation is performed by licensed plumbers or qualified maintenance technicians in commercial and institutional plumbing systems.

Act-O-Matic showerheads are commonly specified in correctional facilities, schools, dormitories, athletic facilities, and other high-traffic commercial or institutional shower applications where automatic shutoff and water conservation are required. The 4328466 kit is the OEM-sourced replacement piston for 2.5 GPM Act-O-Matic units, making it the correct service part for restoring original flow and shutoff performance in those installed assemblies.

Installation Notes
