Product Information

Specification

Enhance Winter Pool Security :

This 6-pack of 8 × 0.94 ft double-chamber pool cover water bags is designed to add reliable weight and keep your pool cover securely in place throughout winter, preventing wind uplift and blocking debris. Ideal for inground pools, these bags are easy to fill, drain, and store—helping you maintain a clean and protected pool all season.

Double-Chamber Anti-Roll Design :

The dual-chamber construction increases internal stability and prevents the bags from rolling or shifting in strong winds. Even during heavy storms, they hold your pool cover firmly in place, making winter maintenance easier and more effective.

Thickened 0.4 mm PVC Material :

Made from durable, flexible 0.4 mm PVC, these winter pool water tubes resist UV exposure, minor impacts, and temperature fluctuations. When filled to 50–70% capacity, they provide stable weight while allowing space for expansion—reducing the risk of bursting in freezing conditions. Suitable for year-round use.

Heavy-Duty Welded Seams :

Each water tube features high-frequency heat-sealed seams with a wide 0.59-inch edge, ensuring excellent leak resistance and long-lasting strength. They withstand harsh sun and freezing weather without cracking or aging, offering dependable performance season after season.

Leak-Proof Twist Cap :

Each water bag is equipped with an easy-turn twist cap featuring a built-in rubber gasket for a tight, leak-proof seal. The anti-loss tether keeps the cap attached, while the threaded design provides better sealing and convenience than traditional snap caps. Tip: Before filling, slide the retaining ring to the bottom of the threaded pattern for optimal sealing.
