Travis Brungardt walks through the replacement of an aging frost-free hose bib at his own home, using the project to explain how anti-siphon, frost-free sillcocks prevent freeze damage. He outlines how traditional hose bibs can trap water near the exterior wall, where freezing temperatures cause expansion and pipe failure. A frost-free design relocates the shutoff point deeper inside the thermal envelope, allowing exterior water to drain and reducing the risk of burst pipes. In the process, Brungardt replaces old CPVC plumbing with PEX, carefully enlarging the exterior opening and fishing new pipe without opening finished basement ceilings, blending practical plumbing repair with building science fundamentals.
