T&S Brass 003164-45 Rubber Spring Check Plunger

A valve plunger designed for commercial faucet assemblies, used to manage internal water direction and help prevent reverse flow within the check valve housing. It operates through pressure response, opening and closing inside the valve body to maintain controlled water movement between hot and cold water systems. The compact, precision-fit design allows it to seat correctly within heavy-duty faucet internals commonly found in foodservice plumbing setups. Found in commercial kitchen sink and washdown faucet systems, this component is used in high-use water delivery points such as prep stations, utility sinks, and cleaning areas. Over time, wear or damage to the plunger can lead to irregular water flow, dripping, or backflow within the faucet assembly. Replacing a worn plunger helps restore proper sealing action and supports normal directional water control during routine operation.
