    Default Insulating water lines

    I know that you have to insulate water lines in an attic or crawl space if you are in an area that requires it per the IRC chart for freezing weather but are there any exceptions such as the flexible water lines like PEX lines?

    Nope, pex will freeze just like anything else. It is less likely to be damaged but the water still freezes.

    INSTALLING QICKPORT MANIFOLDS, cont’d.

    After the manifolds have been installed and the tube size selected, the
    next step is to install the Zurn PEX tube. When installing the tube,
    there are several points that must be considered:
    1.
    Bending

    2.
    Expansion and Contraction

    3
    . Abrasion

    4.
    Heat Sources

    5.
