I am to move into a new house soon and wanted to plumb in a washer into the garage. I have the option of plumbing a line from the bathroom(1st floor) , however this would have to go through the walls of the house into the garage. The only other water supply would be via the kitchen, however the kitchen is the other side of the dining room.
Do I need to take the floorboards up and plumb in through the walls of the house or can I go out around the outside of the house??
Much help appreciated
