The SYMMONS INDUSTRIES 7-225-CK-MS is a mixing valve component designed for controlling the blend of hot and cold water in plumbing systems. Mixing valves are critical components in residential and light commercial plumbing installations, maintaining consistent outlet temperatures and protecting against thermal shock. This cartridge kit provides the internal working parts needed to service or rebuild an existing mixing valve assembly. Licensed plumbers and experienced service technicians typically install or replace this type of component.
This kit is suited for mixing valve service work in residential and light commercial plumbing applications. Mixing valve cartridge kits are typically used when the existing valve exhibits inconsistent temperature control, leaks at the mixing chamber, or general wear that requires a rebuild rather than a full valve replacement. Installation takes place at the point of supply or at fixture-level mixing valve locations depending on the system layout.
Designed as an OEM-style replacement cartridge kit for Symmons Industries mixing valve assemblies. Verify fitment against the installed valve model before ordering.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the water supply and relieve line pressure before disassembling the valve. Inspect the valve body seat and sealing surfaces prior to installing the new cartridge components. Do not overtighten fittings or compression components, as this can damage the cartridge seat or distort sealing surfaces.
