Adding a fridge water line

This Temecula home owner decided to install a fridge in the garage to keep those extra items nice and cold! The only problem was they wanted to make ice cubes as well but guess what? No water supply. So we opened up the wall and tapped into the laundry rooms cold water line. Then we installed a new ice maker shut off valve in the wall and presto! Ice cubes and cold water please! In the garage if you don't mind!
