Do underground water pipes freeze?
Even buried, underground water pipes are subject to freezing. Problems usually arise when soil in new water line trenches has not fully settled, or when earthwork or construction above the pipeline removes too much soil or replaces soil with materials like concrete that conduct heat away more easily.

Can you run an extension cord through PVC pipe?
While you are using it you can run it through a section of PVC pipe as it runs along the edge of the deck against the house so it doesn’t fall in the crack. The pipe must be fat enough so the plug slips through and the cord is removed from the pipe before being put away for the day.
