Check valve that prevents water backflow in the appliance's supply line, helping restore proper water flow to the ice maker or dispenser. Replaces a failed valve to address leaking, slow fills, or no-fill conditions. What it does:

• Stops reverse flow in the water line so water only moves toward the dispenser or ice maker
• Helps prevent water leaks and cross-contamination of the supply line
• Common symptom fixes: intermittent or no water to ice maker/dispenser, weak fills, or water pooling
• Fits inline with existing water tubing and works with the appliance's fill system

• Shut off water supply and unplug the appliance before replacing the valve
• Confirm tubing size and orientation before installation; install with correct flow direction
• Tighten fittings to prevent leaks but avoid overtightening plastic fittings
