Product Information

Specification

Enhance Winter Pool Security :

This 5-pack of 8 × 0.94 ft double-chamber pool cover water bags provides reliable weight to secure your pool cover during winter, preventing wind uplift and debris from entering. Ideal for in-ground pools, these bags are easy to fill, drain, and store—saving you time and effort during winter cleanup.

Double-Chamber Anti-Roll Design :

The pool cover water tubes feature a double-chamber construction that increases stability and prevents rolling or shifting in strong winds. Even during heavy storms, they keep your pool cover firmly in place, making pool maintenance easier.

Thickened 0.4 mm PVC Material :

Made from durable, flexible 0.4 mm PVC, these winter water tubes resist UV exposure and minor impacts. When filled to 50–70% capacity, they provide secure, balanced weight while leaving room for expansion—reducing the risk of bursting caused by temperature changes. Suitable for year-round use.

Heavy-Duty Welded Seams :

Each inground pool water tube is built with high-frequency heat-sealed edges and wide 0.59-inch seams, ensuring excellent leak resistance and long-lasting durability. They withstand both intense summer sun and winter frost without cracking or aging, offering reliable performance season after season.

Leak-Proof Twist Cap :

Each water bag includes an easy-turn twist cap with a built-in rubber gasket for a tight, leak-proof seal. The anti-loss tether keeps the cap attached, and the upgraded twist design provides better convenience and sealing power than traditional snap caps.
Tip: Before filling, slide the retaining ring to the bottom of the spiral thread for the best seal.
