Tapco M964905-0071600 Piston Assembly 1.6 Gpm

Product Description

The TAPCO M964905-0071600 is a piston assembly designed for 1.6 GPM flush valve applications. The piston assembly controls water flow within a flush valve, regulating the volume and timing of each flush cycle. This component is a direct service part intended for use in commercial or institutional restroom plumbing systems where flush valves require rebuild or replacement. Licensed plumbers and experienced facilities maintenance technicians are the typical installers of this part. The 1.6 GPM flow rate aligns with low-consumption flush valve standards commonly required in commercial building codes.

This piston assembly is suited for flush valve service work in commercial restrooms, schools, healthcare facilities, and other high-traffic environments. It is identified as an American Standard flush valve replacement component, making it applicable to systems using that platform. When a flush valve exhibits slow cycling, incomplete flushing, or continuous running, a worn piston assembly is a common root cause and a standard first-replacement item.
