Step 2 · Shut Off Water Supply and Prepare Area
Locate the water shutoff valve for the refrigerator, which is often a small saddle valve on a pipe under the sink or in the basement. Turn the valve clockwise until it is fully closed. Next, carefully pull the refrigerator away from the wall to access the water line behind it. Be mindful of the flooring. To relieve pressure in the line, dispense a glass of water from the refrigerator's door dispenser until it stops flowing. Place towels on the floor where you will be working.
