Brasscraft ST3546B Diverter Stem

Product Description

The BRASSCRAFT ST3546B is a replacement diverter stem designed for faucet and shower valve service. The diverter stem controls flow direction within the valve body, redirecting water between outlets such as a tub spout and showerhead. This part cross-references to American Standard application 9803-02 and is installed by licensed plumbers or experienced pipe tradespeople during valve repair or rebuild service. It is a direct OEM-style replacement intended to restore proper diverter function without replacing the entire valve assembly.

The ST3546B is suited for residential faucet and shower diverter valve repair. It fits into the valve body in place of a worn or failed original stem, making it appropriate for tub and shower combination fixtures where diverter function has degraded. Technicians typically source this stem when rebuilding a valve that is leaking, failing to divert, or passing water to both outlets simultaneously.

Key Features

Compatibility

Installation Notes

Installation is performed by a licensed plumber. Shut off the water supply to the fixture and relieve line pressure before removing the existing stem. Standard plumbing hand tools are sufficient for stem removal and seating; consult IPC guidelines for service procedures. Inspect the valve seat and packing for wear before installing the replacement stem.
