Prevent Ice Damage

As water freezes, it expands. Without an air pillow, this pressure can crack your pool walls or stretch your winter cover to the breaking point.

Actionable Steps

Using Air Pillows

Air pillows (ice equalizers) break up the surface tension of freezing water. Don't inflate them to 100%—leave some room for compression.

⚠️

Safety Warning: Secure pillows in the center of the pool with twine to prevent them from drifting to the edges.

Pro-Tip

Inflate your pillows to roughly 70%. When ice expands and squeezes them, it needs room to compress. A 100% inflated pillow will pop like a balloon.
