A skimmer Gizzmo is a hollow, non-collapsible plastic tube that threads into the bottom of your skimmer line after it is blown out and sealed. It acts as a sacrificial freeze-expansion vessel, absorbing ice pressure so your skimmer housing doesn’t crack during freezing Canadian winters.

• Crucial for Mesh Safety Covers: Mesh safety covers allow rain and melting snow to drain straight into the pool, raising the water level over the winter. When water creeps back into the skimmer housing and freezes, the Gizzmo crushes inward to protect the rigid PVC plastic from cracking.
• Dual-Purpose Protection: In addition to absorbing ice expansion, it seals the top of the pipe to keep dirt and water out of your cleared plumbing lines.
