The Water Line Union is an OEM part for LG refrigerators. This component connects sections of the water line, ensuring a secure and leak-free passage of water to the refrigerator's icemaker and water dispenser. It is an elbow tube union connector, which connects two tubes at a 90-degree angle.

Causes of a bad water line union can include wear and tear from frequent use, damage from high water pressure, or deterioration due to mineral buildup and age. A compromised union can lead to water leaks and disruption in the water supply.

Symptoms of a bad Water Line Union include:

• Water leaks around the connection points
• Reduced water flow to the icemaker or water dispenser
• Puddles or moisture near the refrigerator
• Unusual noises from the water line
