If your new refrigerator comes equipped with an icemaker, you may not need to call the plumber to hook it up.

Step 1: To tap into an existing water line, measure the distance from the water line to the back of the refrigerator. Purchase a quarter-inch, stainless-steel flex line, copper tubing or plastic tubing long enough to reach from the water line to the refrigerator, allowing enough extra line to pull the refrigerator away from the wall.

Step 2: Drill a hole in the floor behind the refrigerator to route the water-supply line through. Make sure the hole is large enough for the compression nut at the end of the tubing to slide through, but small enough that nothing else will come through the hole once the tubing is inserted.

Step 3: Use the main shutoff valve to turn off the cold-water supply.

Step 4: Open the cold-water side of the faucet along the water line you have shut off and allow the remaining water to drain out. Leave the faucet open while you work on the water line.

Step 5: To route the water from a copper water line, secure a self-piecing, quarter-inch compression valve to the underside of the copper tubing using the clamp portion of the valve. If you have galvanized pipe, drill a 3/16-inch hole on the underside of the pipe first and then position the valve on the hole. Once the valve is secure, tighten down the piercing portion of the valve by turning the handle clockwise as far as it will go.

Step 7: Use a quarter-inch compression nut to attach the tubing or supply line to the self-piercing valve. Hand-tighten the nut and then use an adjustable wrench to turn the nut one-half of a turn more. If you are using plastic tubing, place a brass insert inside the tubing end first. This will keep the tubing from collapsing under the pressure of the nut.

Step 8: Place the open end of the supply line or tubing into a bucket, and turn the water supply on to flush the line of any debris.

Step 9: Turn the water supply back off and snake the supply line to the refrigerator and attach it. Hand-tighten the compression nut and then use an adjustable wrench to turn it a half-turn more.

Step 10: Turn the water supply back on. Check for leaks. Make any necessary adjustments. Push the refrigerator back into place, and relax while the icemaker makes your world a little cooler.
