How to Change a Water Line for a Refrigerator: Step-by-Step Guide

A damaged or leaking refrigerator water line can lead to costly water damage and reduced appliance performance. Fortunately, replacing a water line is a manageable DIY project with the right tools and a little know-how. Here’s a complete guide from PRS Parts Inc. to help you do it right.

Tools & Materials You’ll Need

  • Replacement water line (OEM recommended for the best fit and durability)

  • Adjustable wrench

  • Bucket or towel (to catch water drips)

  • Teflon tape

  • Shut-off valve (if replacing)

  • Utility knife or tubing cutter

Step 1: Turn Off the Water Supply

Locate your refrigerator’s water shut-off valve—usually found behind the fridge, under the sink, or in the basement—and turn it off. If there’s no dedicated valve, shut off the main water supply to your home.

Step 2: Unplug the Refrigerator

Safety first—always disconnect the appliance from its power source before starting any repair work.

Step 3: Disconnect the Old Water Line

  • Pull the refrigerator away from the wall.

  • Place a bucket or towel beneath the connection to catch any water.

  • Use an adjustable wrench to loosen and disconnect the water line from both the fridge and the shut-off valve.

Step 4: Install the New Water Line

  • Wrap Teflon tape around the threaded ends to ensure a watertight seal.

  • Attach one end of the new water line to the shut-off valve and tighten with the wrench.

  • Connect the other end to your refrigerator’s water inlet.

Step 5: Check for Leaks

  • Turn the water supply back on slowly.

  • Inspect both ends of the connection for any drips.

  • If you see leaks, tighten the connections slightly until they stop.

Step 6: Push the Refrigerator Back and Test

Plug the fridge back in, push it gently back into place, and run the water dispenser or ice maker to confirm everything is working.

Pro Tips from PRS Parts Inc.

  • Always use OEM (Original Equipment Manufacturer) water lines for the best fit and long-lasting performance.

  • If your current shut-off valve is old or corroded, replace it during the installation.

  • Avoid over-tightening connections to prevent stripping or damage.
