What You Will Need
To determine how much copper tubing you need:
Measure the distance from the water valve on the back of the
refrigerator to the water supply pipe. Then add 8 feet (244 cm).
Be sure there is sufficient extra tubing [about 8 feet (244 cm)
coiled into 3 turns of about 10 inches (25 cm) diameter] to allow
the refrigerator to move out from the wall after installation.
A cold water supply. The water pressure must be between
20 and 120 p.s.i.
Power drill.
Copper tubing, 1/4" outer diameter to connect the refrigerator to
the water supply. Be sure both ends of the tubing are cut square.
Do not use plastic tubing or plastic fittings because the water supply line is under
pressure at all times. Certain types of plastic tubing may become brittle with age
and crack, resulting in water leakage.
Two 1/4" outer diameter compression nuts and 2 ferrules (sleeves)—
to connect the copper tubing to the shutoff valve and the
refrigerator water valve.
If your existing water line has a flared fitting at the end, you will
need an adapter (available at plumbing supply stores) to connect
the water line to the refrigerator OR you can cut off the flared
fitting with a tube cutter and then use a compression fitting.
Shutoff valve to connect to the cold water line. The shutoff valve
should have a water inlet with a minimum inside diameter of
5/32" at the point of connection to the COLD WATER LINE. Saddle-
type shutoff valves are included in many water supply kits. Before
purchasing, make sure a saddle-type valve complies with your
local plumbing codes.
Shut Off the Main Water Supply
Turn on the nearest faucet long enough to clear the line of water.
