How to Connect Your Refrigerator Water Line Safely

Adding a water line to your refrigerator allows you to enjoy cold water and ice on demand, but connecting it incorrectly can lead to leaks or water damage. Whether you’re installing a new fridge or replacing an old one, following the right steps ensures a safe and reliable setup.

Tools and Materials You’ll Need

Before starting, make sure you have the following:

• Adjustable wrench

• Drill (if a new line needs to be run)

• Compression fittings or push-to-connect fittings

• ¼-inch copper or braided stainless-steel tubing

• T-valve or shut-off valve

• Teflon tape

Process to Connect Your Refrigerator Water Line

1. Turn Off the Main Water Supply

   Always shut off the water before cutting or connecting any lines.

2. Locate the Nearest Cold-Water Line

   Most refrigerators connect to the kitchen sink’s cold-water pipe or an existing valve behind the fridge.

3. Install a T-Valve or Saddle Valve

   This valve allows water to flow from the main line into the refrigerator’s tubing. A T-valve is recommended for a more durable and code-compliant connection.

4. Attach the Water Line Tubing

   Connect the tubing to the valve and tighten it with a wrench. Avoid over-tightening it can damage the fittings.

5. Connect the Tubing to the Refrigerator Inlet

   Carefully attach the other end of the tubing to the refrigerator’s water inlet, usually found at the back of the unit.

6. Turn On the Water Supply and Check for Leaks

   Slowly turn on the valve and inspect all connections for drips or moisture. Tighten connections if needed.

Safety Tips

• Never use plastic tubing it’s prone to leaks and cracking.

• Use stainless steel or copper lines for durability.

• Check for moisture regularly behind the refrigerator.

• Always have a shut-off valve installed for emergencies.

• If you’re unsure about plumbing connections, call a licensed plumber.
