Replacing refrigerator water line shut off valve

Your refrigerator dispenses refreshing ice and water all year long... as long as it's connected to a water supply line. You can use the water line leftover from your previous refrigerator, or start fresh with a new kit from the hardware store. Either way, we're going to help you get your home water-ready.

If your home doesn't have a water line installed from a previous refrigerator, you will need a water line that can run between the water pipes in your home and your fridge. Water lines are typically sold in kits and are not included with the refrigerator. We recommend using a water line installation kit that uses 1/4 inch copper tubing, a 1/4 inch compression nut, and a ferrule. Keep in mind that you will need a compression nut at both ends, and some kits only come with one.

This procedure will vary depending on the type of equipment you are using, so follow the kit's instructions. You can also use our instructional video and steps if you're unsure.

1. In most installations, the fundamentals include attaching a shut off valve (C)  to your cold water line (A) using a pipe clamp (B). Please refer to the first image for this step.

2. Then, you'll need to twist the valve until it pierces your water line.

3. After that, you'll need to connect the rest of the water line installation kit (D) to the shut off valve (C). Please refer to the second image for this step.
   

Note: For the ice maker to operate properly, a minimum water pressure of 30 psi is required. If needed, you can install a booster pump to compensate for low pressure. After installation, check the water pressure by dispensing water. It should take less than 10 seconds to dispense 3/4 cup.

Note: The RS27T and RS22T models have two water lines to connect, which is not shown here. If they are cross-connected, the water and ice dispensing functions will not work correctly. If you have one of these models and the dispenser has not worked since installation, refer to the user manual to check that these lines are correctly installed.

The water supply line is not included with the refrigerator and is typically sold as a kit at your local hardware store (if you don't have one already installed in your home). We recommend getting a 1/4 inch copper tubing kit, which should include 1/4 inch copper tubing, a 1/4 inch compression nut, and a ferrule.

A plastic tubing kit should include 1/4 inch plastic tubing with a molded end/bulb, and a 1/4 inch compression nut. If you use plastic tubing, do not use it without the molded end/bulb. Please note that a plastic tubing kit is not recommended.

Please refer to the image to see what the connection will look like using either type of tubing. This image is also available in your user manual. The ferrule for copper tubing, the molded end/bulb for plastic tubing, and the 1/4  inch compression nut for both tubing options will be provided in the purchased kit.

• (01): 1/4 inch compression nut 

• (02): Ferrule for copper tubing 

• (04): Plastic tubing leading to the fridge

• (05): Compression fitting

• (06): Molded end/bulb for plastic tubing 

• (07): 1/4 inch compression nut for both tubing options 

• (A): Section that leads to the refrigerator

• (B): Section that leads to the household water supply line

• (C): Demonstrates how the tubing will appear when installed

Use the instructions below to connect the water supply line:

1. Slip the compression nut (07) onto the tubing provided in the kit. If you are using copper tubing, also slip on the ferrule (02). If you are using plastic tubing, insert the molded end/bulb (06) directly into the compression fitting (05).

2. Tighten the compression nut (07) until it reaches the compression fitting (05). Do not over-tighten it, as over-tightening will cause a leak.

3. Turn the water on and check for leaks. If you find water drops or a leak in the connection areas, turn off the main water supply. Check the connections, and tighten when necessary.
   

4. If the model has a dispenser, make sure the water filter is installed.  Then, dispense one gallon of water before drinking or using any water from the refrigerator.
   

5. The first time you turn on the ice maker, let it make ice for 1 to 2 days. Over that period of time, throw out the first 2 buckets of ice to ensure all impurities have been removed from the water line.
