Hook up ice maker to sink
You would connect one of the female ends from the flex line to the valve in the wall and then connect the other end of the flex line to the back of the refrigerator.
Required Tools for this Project
Find your water supply lines beneath your sink. Carefully move the refrigerator out from the wall, and remove any kickplates installed on the lower part of the cabinet on the floor. If there is no water dispenser, throw away the first full batch or two of ice to make sure it is all clean and ready to use.
To start, locate the cold water source nearest to the refrigerator—perhaps under the kitchen sink, below the floor, in the wall or even in the ceiling.
Now turn on the faucet shutoff hook up ice maker to sink under the sink and check for leaks at the Adapt-a-Tee connections. MORE as needed, using channel-type pliers or an adjustable wrench.
If the refrigerator has a water dispenser, flush out several Slip the compression nut that came with the kit over the newly installed supply line. Then slide on the compression fittings, lubricate the threads on the refrigerator fitting with pipe compound and screw on the tubing.
This can cause a leak. You can solve this with an ice maker installation kit that allows you to use the plumbing beneath the sink. Position the valve on top of the cold water line with the clamp on the bottom.
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. Tools and Materials You Will Need.
In this kitchen, we ran the new water line from under the kitchen sink through cabinets. Loosely run the line under the cabinets leaving enough slack so there is no tension on the line.
Plumb the fridge
Use pliers to untwist the faucet supply line from the cold water supply valve. If the line is just a replacement, Follow all of the same steps with the exception of drilling the hole in the cabinet and adding the valve, then screw the nut with the line on the existing valve. The refrigerator water line will then need to go through the cabinets, if possible, and come out just behind the refrigerator. If so, your job is very easy. Usually, this will be at some other existing water hookup, like the water supply lines connected to your sink faucet or dishwasher.
The valve connected to the right side of the faucet is the cold water supply line. Tighten the flex line using two adjustable pliers. Saddle valves tend to not last as long as a normal shut off valve because they are so small but they will get the job done. Then attach the tubing to the back of the cabinets every 2 to 4 ft. We just paid a plumber to install this very things.
