Larsen Supply Co S-1121-4 Shower Diverter Stem

Product Description

The Larsen Supply Co. S-1121-4 is a replacement shower diverter stem designed to fit Price Pfister 6125 series faucets with a B broach configuration. The diverter stem controls the flow of water between the tub spout and the showerhead, redirecting water when the diverter handle is actuated. This part is sold individually and is a direct OEM-style replacement intended for licensed plumbers and experienced service technicians performing faucet rebuilds or valve repairs in residential bath and shower applications.

This shower diverter stem is used in tub and shower faucet valve bodies where the original Price Pfister 6125 stem has worn, cracked, or failed to divert water properly. The B broach designation refers to the stem handle interface, which must match the existing handle broach pattern for proper fitment. Typical installation scenarios include routine faucet repair, leak elimination, and diverter rebuild service on residential tub-shower combinations.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply to the fixture and relieve line pressure before removing the existing stem. Inspect the valve seat and packing area for wear or damage before installing the replacement stem. Do not overtighten the stem, as this can damage the packing or valve body threads.
