The Gizzmo Winterizing Tubes are a savior for pool skimmers during the cold winter months. As temperatures drop in the winter, and water starts to freeze, the ice expands and creates pressure that can damage pipes and crack skimmers. Rather than putting pressure on the skimmer, the Gizzmo Winterizing Tube compresses and absorbs the pressure, which then in turn relieves the pressure in the skimmer and plumbing created by the ice protecting them from damage.
