DIY steps
- Shut off the water supply to the icemaker by locating the shut-off valves behind the refrigerator and turning them clockwise. Open the refrigerator door and pull out the icemaker drawer to access the back of the fridge. Wear protective gloves and safety glasses to prevent injury from sharp edges or flying debris.
- Locate the water supply line that comes with the icemaker and cut it to the desired length using a utility knife or tubing cutter. Remove any protective caps from the ends of the supply line and discard them.
- Install a listed tee or adapter and dedicated quarter-turn shutoff valve compatible with the existing cold-water pipe; do not treat a saddle valve as an end-of-line threaded fitting. Follow the fitting manufacturer's instructions and do not overtighten.
- Connect the icemaker supply line to the dedicated shutoff using the fitting and sealing method specified by the line manufacturer. Tighten only as specified, then support the line so it cannot kink or rub.
- Turn the water supply back on and check the connections for leaks by running a bucket under the icemaker to catch any water that may drip out.
- Clean up any spills or messes made during the installation process, and dispose of any packaging materials from the icemaker supply line and saddle valve.
