Plastic pipe is ok in south texas and such, where it might freeze 1-2 times in 30 years. further north you are 100% correct. Most home depos have 2 kinds of copper pipe, the red writing is the normal, the one with the blue will last though more freezes. If you have shit on exterior walls, wrap with heat tape.
