How To Hook Up A Water Line To A Refrigerator From The Sink
Dec 07, 2016
A refrigerator with an automated ice maker and a built-in water dispenser does absolutely nothing if you do not have a water line to connect to it. Many homes have a refrigerator water supply line installed during initial construction, but this feature wasn’t included in the original building plans of some homes. You can solve this with an ice maker installation kit that allows you to use the plumbing beneath the sink. The kit provides you with the required parts to hook up a water line to your refrigerator.
Find your water supply lines beneath your sink. You may have three water supply lines beneath the sink; two lines connect directly to the faucet while the third line connects to the dishwasher. The valve connected to the right side of the faucet is the cold water supply line. Turn the cold water on the supply line clockwise to close it.
Attach a 5/16-inch drill bit to your drill. Drill holes in the base cabinet walls to route the water line from beneath the sink to the rear of the refrigerator. Drill as close to the back wall of the cabinet as possible, so you do not lose storage space inside the cabinet.
Thread the water line, included in the ice maker installation kit, from the area behind the refrigerator to beneath the sink. Leave the excess water line behind the refrigerator.
Turn on the cold water faucet to drain any water left in the supply line. Use pliers to untwist the faucet supply line from the cold water supply valve.
Wrap threads on the cold water valve with two or three wraps of thread-seal tape. Twist the male end of a quick-tee adapter onto the valve. Wrap the female thread on the opposite end of the adapter with thread-seal tape. Twist the faucet supply line onto the female end of the adapter.
Slip the compression nut that came with the kit over the newly installed supply line. Make sure the threads are facing the end of the line. Thread the ferrule from the kit onto the new line.
Wrap the remaining male threads on the quick-tee adapter with thread-seal tape. Insert the new water line into the opening on the tee. Slide the compression nut over the male threads and tighten it on the adapter.
Tighten all three nuts on the quick-tee adapter with pliers or an adjustable wrench. Do not twist the nuts too tight as this could damage the supply valve, the supply line and the adapter.
Place the end of the water line you intend to connect to the refrigerator into a 5-gallon bucket. Turn the cold water supply valve on beneath the sink. Let 1 or 2 gallons of water run through the new line to remove the air. Turn off the supply line.
Slip the remaining compression nut and ferrule over the refrigerator end of the new water line. Connect the line to the water line connector on the back of the refrigerator.
Turn the supply line on once again. Watch for leaks at all the connections. Tighten the connections slightly if you see a leak. If tightening the connection does not stop the leak, turn off the water, remove the connector and add additional thread-seal tape before reconnecting the water line.
Plug your refrigerator into the wall. Coil the excess water line behind the refrigerator. Push the refrigerator against the wall.
