How to install refrigerator water line?


Installing a water line for your refrigerator is a convenient way to have access to filtered water and ice without the need for constantly refilling water pitchers or ice trays. This article will guide you through the process of installing a refrigerator water line, ensuring that you have a steady supply of clean and cold water at your fingertips.

Gather the Materials

Before you begin the installation process, it is essential to gather all the necessary materials. Here are the items you will need:

– Refrigerator water line kit (includes tubing, fittings, and valve)
– Adjustable wrench
– Pipe cutter or hacksaw
– Drill
– Drill bit suitable for the tubing size
– Teflon tape
– Screwdriver
– Pliers

Locate the Water Source

To install a refrigerator water line, you need to find a suitable water source. The most common options include a nearby cold water pipe, a water line under the sink, or a dedicated water supply line. Ensure that the water source is accessible and can provide a clean water supply.

Shut Off the Water Supply

Before making any connections, it is crucial to shut off the water supply. Locate the main water shut-off valve and turn it clockwise until it is fully closed. This step will prevent any water from flowing while you work on the installation.

Prepare the Refrigerator

Next, you need to prepare your refrigerator for the installation. Move the refrigerator away from the wall to create enough space for you to work comfortably. Make sure you have easy access to the back of the refrigerator.

Install the Water Line

1. Begin by attaching the compression fitting to the cold water supply line. Use an adjustable wrench to tighten the fitting securely.

2. Measure the distance from the water source to the back of the refrigerator. Add a few extra inches to allow for any necessary adjustments.

3. Using a pipe cutter or hacksaw, cut the refrigerator water line to the measured length. Ensure that the cut is clean and straight.

4. Attach the compression fitting to one end of the cut tubing. Use an adjustable wrench to tighten the fitting.

5. Thread the other end of the tubing through the hole in the back of the refrigerator. Be careful not to kink or damage the tubing during this process.

6. Connect the tubing to the water valve on the back of the refrigerator. Again, use an adjustable wrench to tighten the connection securely.

7. Turn on the water supply by opening the main water shut-off valve. Check for any leaks at the connections. If you notice any leaks, tighten the fittings further or apply Teflon tape to create a watertight seal.

Test the Water Line

After completing the installation, it is essential to test the water line to ensure everything is functioning correctly. Follow these steps:

1. Plug in the refrigerator and push it back against the wall.

2. Dispense water from the refrigerator’s water dispenser. Check for any leaks or irregularities in the water flow.

3. Activate the ice maker and observe if it fills with water correctly.

If you encounter any issues during the testing phase, double-check the connections and make any necessary adjustments.


Installing a refrigerator water line is a relatively straightforward process that can provide you with a convenient supply of filtered water and ice. By following the steps outlined in this article, you can ensure a successful installation and enjoy the benefits of having a connected water line for your refrigerator.
