The SYMMONS INDUSTRIES 556708 is a replacement cartridge designed for use in Symmons faucet and valve assemblies. Cartridges are the internal control components that regulate water flow and temperature within a faucet body. When a faucet develops a drip, becomes stiff to operate, or loses temperature control, the cartridge is typically the component requiring service or replacement. This part is installed by licensed plumbers and experienced service technicians performing faucet repair and maintenance in both residential and light commercial plumbing systems.
This cartridge is suited for faucet repair applications where the original Symmons cartridge has worn, cracked, or failed. It is intended for use in systems where the existing faucet body is sound and only the internal cartridge assembly requires replacement. The part is identified in supplier data as a KN-4 type cartridge, which may indicate a specific valve family or cartridge series within the Symmons product line.
Designed as an OEM-style replacement cartridge for Symmons faucet and valve assemblies requiring a KN-4 series cartridge. Consult the original fixture documentation or Symmons service literature to confirm fitment before installation.
Cartridge replacement is typically performed by a licensed plumber. Shut off the water supply to the affected fixture and relieve line pressure before disassembling the faucet body. Follow IPC guidelines for faucet service and refer to the fixture manufacturer documentation for cartridge removal and seating procedures. Do not force the cartridge into position, as improper seating can cause leaks or damage to the valve body.
