Outdoor extension of hose spout
PEX stands up pretty well to freezing. It's amazing what you can do to it and how it recovers. Freezing isn't a problem for PEX.  Still I would recommend draining it during the winter via a drain spigot at a low point in the plumbing. Depending upon the plumbing configuration, you may have to &quot;blow it out&quot; using compressed air.
