How do you move a washing machine into a garage?

Is the garage subject to freezing temperatures? If so it is not something you would want to do. All supply lines and drainlines would have to be plumbed to that location and drain lines would have to be properly vented. I would suggest a plumber for a job of this magnitude and to ensure that it is properly done. Todays washers require a minimum of 2" diameter piping for the drain capeable handling flows of about 17-18 GPM.
