Ok, did some kitchen remodeling and moved a wall back 4'. This moved the location of the fridge. I ran a new water line to the fridge via the attic from water line coming into the house in the garage. I live on a slab and the sink is on the other side of the kitchen seperated by an arch way making it difficult to run water line thru wall without doing some major dry wall demo and repair. My quistion is, living in northern Indiana what are the odds the line freezes even if I insulate?? Are there options for running plumbing thru attics or is this a major no no??
