A water pipe anti-rupture system for preventing freeze damage provides for an injection molded string of hollow cups spaced apart by a common connecting rod. Periodically spaced cross stabilizing leg members are disposed in a plane perpendicular to the connecting rod for frictionally engaging the inside of a water pipe to hold the cups in place substantially in the center and along a length of water pipe with hollows down so that they can entrap air. This system prevents bursting of the pipes when water freezes.
