Is there a freeze-proof copper pipe?

    Is there such a pipe, copper or otherwise, that doesn't matter if it
    freezes? My pipes up to the upstairs bathroom run within an outside
    wall, and while its inside the insulation it has frozen before, luckily
    never burst, but I don't trust it to do that again!

    No such luck. Even with water off and the pipes poorly drained, residual
    water can freeze and break pipes.
    I have never had it happen, but I have had a water filter break because
    there was a little water left in it.

    Supposedly pex will can tolerate freezing. Perhaps someone will elaborate
    on that.

    It may help in some cases, but often the arrestor is too far away. Water
    expands 17% when it freezes and can easily do lots of damage.

    PEX would be a better product in a potential freeze up though.

    It's an old story... If you run pipes in an outside wall in a climate
    subject to freezing, you're going to have trouble.

    Best to relocate the pipes in the heated space and cover them with
    insulation if there is any doubt.

    I would put heat tracing on them and insulate.
