Running a water line to a refrigerator to supply its ice maker and drinking water dispenser has never been easier. This type of fitting is easy to install and is less prone to leaking than a saddle valve. In most cases, the water line can be run from a kitchen faucet water supply line through the kitchen cabinets and over to the refrigerator. If running the line through the cabinets is not feasible, you might need to run it through the floor and up to where the refrigerator is located.

Here is a step-by-step water line installation refrigerator guide. A new refrigerator with a water dispenser and ice maker needs to be hooked up to a COLD water line. Usually behind where a refrigerator is installed, there will be a water valve that you can use to hook cold water to your fridge. If there is no water valve behind your fridge, you will have to run a water line to the closest cold water pipe to get your refrigerator access to water. You may have a cold water pipe either behind the wall where the fridge is or possibly in the floor under the kitchen.
Another good alternative would be to use a braided stainless steel line, but they are double the price. Whenever installing plastic pipe with compression fittings such as these, you always want to use plastic ferrules. The ferrule, AKA sleeve or olive, is the part the compresses on to the pipe which makes for a leak free joint. If you use a brass ferrule, you run the chance of it cutting thru the pipe and causing the fitting to leak, this is where most DIYers make a mistake that could potentially lead to a disaster. Another thing to keep in mind is using a brass sleeve inside the pipe.
