How can I properly install a fridge water supply line to ensure a reliable and efficient water connection for my refrigerator?

To properly install a fridge water supply line, first turn off the water supply, then connect the line to the water source using a compression fitting. Next, route the line to the back of the fridge, leaving some slack for movement. Secure the line in place and turn on the water supply to check for leaks. Finally, flush the line to remove any air and debris for a reliable and efficient water connection.
