Leaks in a Refrigerator Valve Compression Fitting

Valve Compression Fitting Basics

• The valve compression fitting is found on the water supply line, typically a copper tube on most refrigerators. The fitting opens to allow water to flow through the tube when you press the water dispenser lever or when the refrigerator needs to make ice and then closes when water isn’t needed anymore. The fitting is located close to the end of the water supply line that connects to the refrigerator. You can generally view the component by pulling out your refrigerator from the wall to expose its back side.

Symptoms of a Leaky Valve Compression Fitting

• If a valve compression fitting fails, you can expect to find water collecting both inside and outside the refrigerator. Water may appear on the refrigerator's shelves or at the base of its cabinet. Additionally, you may find water trickling from the dispensers and onto the kitchen floor. You may also find water pooling behind your refrigerator where the fitting is located.

Stop Leaks

• If the valve compression fitting is leaking, tighten its nut to stop it. Using a standard wrench, turn the nut clockwise until it's tight. If the valve is damaged, tightening its nut may not repair the leak. In this case, the entire fitting must be replaced. Contact a refrigerator repair technician to perform the repair to ensure its done right and the leak doesn’t return.

Considerations

• Sometimes a cracked water supply line can be mistaken for a valve compression fitting leak, especially since both components are connected together. Examine the water supply line’s copper tubing for signs of wear. If you feel moisture on the tube, the tube may be punctured or splitting from normal use. Contact a refrigerator repair technician to replace the bad tube with a new one.
