How to install a water line for a fridge?

To install a water line for a fridge, you will need to first locate a nearby water source, such as a kitchen sink or a water line in the basement. Next, shut off the water supply and connect a water line to the source using a saddle valve or a T-fitting. Run the water line behind the fridge and secure it in place. Finally, connect the water line to the fridge's water inlet valve and turn on the water supply to test for leaks.
