The LARSEN SUPPLY CO., INC. S-925-4 is a shower diverter stem designed as a replacement part for Sterling 5233 faucet assemblies using a D broach configuration. The diverter stem controls the flow of water between the tub spout and the showerhead by redirecting water through the appropriate outlet when engaged. This type of stem is a common service part in residential shower and tub-shower combination faucets. Licensed plumbers and experienced plumbing service technicians install this part during valve repair or rebuild work when the original stem has worn, cracked, or failed to seat properly.
This diverter stem is suited for residential bathroom plumbing applications, specifically tub-shower combinations where a diverter function is integrated into the faucet valve body. The D broach interface is a standardized drive configuration that must match the existing handle and cartridge seat geometry in the faucet assembly. It is sold individually per card and is packaged in units of six cards per package, making it a practical stocking item for plumbing wholesale and supply counters.
Designed as a replacement shower diverter stem for Sterling 5233 faucet assemblies with a D broach drive configuration.
Installation should be performed by a licensed plumber or qualified plumbing technician. Shut off the water supply to the affected fixture and relieve line pressure before disassembling the valve. Confirm that the D broach profile and stem length match the existing valve body before installation. Follow all applicable local plumbing codes, including IPC guidelines, when servicing shower and tub-shower valve assemblies.
