Customer Questions and Answers for Check Valve (Water Line) by Lg

This check valve is a one-way valve used in the refrigerator's water line. It prevents backflow to maintain pressure for the dispenser and ice maker, helping reduce drips and ensuring consistent water delivery.

• Allows water to flow in one direction only to prevent backflow
• Helps maintain line pressure for steady dispensing and proper ice fills
• May reduce post-dispense dripping at the water outlet
• Failure symptoms can include slow/sputtering dispense, dripping, or inconsistent ice fills

• Unplug the appliance and shut off the household water supply before servicing
• Dispense water to relieve pressure; place a towel to catch residual water
• Note the valve's orientation/flow direction and tubing routing before removal
• Fully seat tubing and secure connections; restore water and check for leaks
