Mobile Home Remodel - Install Ice Maker Water

Today, we are backing up a bit and removing some drywall to install a plumbing fixture to get water to the fridge. This water line supplies the ice maker in the fridge. The original installation has the plumbing entering the room through the subfloor, and in a location directly below the fridge; not good. We need to move it up and into the wall where it will be safe.
