The Gizzmo is designed to screw into your pool skimmer and seal the plumbing lines leading to your pump. This will prevent water from leaking through the skimmer. When ice begins to form, the Gizzmo will absorb the pressure and prevent your skimmer from being damaged. The gizzmo will crush inwards as the ice forms instead of the ice pushing outwards against the skimmer walls causing cracks. Works on almost all standard pools!
Standard 1.5" thread for regular skimmers or Super 1.5/2 inch thread for big deep skimmers.
Remember to protect your pool with Gizzmo!
