Tapco 12316-0070A Diverter Stem Assembly Tub Valve

Product Description

The TAPCO 12316-0070A is a diverter stem assembly designed for tub valve applications in the Williamsburg series. This component controls the flow diversion between the tub spout and the shower outlet by engaging the internal stem mechanism within the valve body. It is a direct replacement part intended for licensed plumbers and experienced service technicians performing tub valve repairs or rebuilds on residential bath fixtures.

This diverter stem assembly is used in tub and shower valve repairs where the original stem has worn, cracked, or failed to hold diversion pressure. It fits within the Williamsburg tub valve configuration and is suited for residential plumbing applications. Technicians typically encounter this repair in older bathroom fixtures requiring valve stem restoration rather than full valve replacement.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply to the fixture before disassembly and relieve any residual pressure by opening the faucet. Remove the handle and trim to access the valve cartridge housing before extracting the worn stem. Inspect the valve seat for wear or corrosion before installing the replacement stem assembly.
