GLI 8ft Heavy Double Blue Waterbag - 500008WTDHDBLU

PROMOTION: Buy 2 or more Waterbags and save 10% on your order! Protect your investment with the GLI 8ft Heavy Double Blue Waterbag. Engineered by GLI, a leader in pool winterization, these bags are designed to keep your solid pool cover perfectly in place even through the harshest wind, snow, and ice.

Why Choose the Double-Tube Design?

Unlike standard single waterbags, the double-tube design provides a wider footprint and extra stability. If one side happens to get a puncture, the other side stays full to maintain tension on your cover, preventing costly cover slippage and debris entry.

Key Features

• Heavy-Duty Construction: Made from high-gauge, UV-resistant vinyl to withstand freezing temperatures and sun exposure.
• Leak-Resistant Valves: Features a secure, easy-to-fill leak-proof valve that stays shut all winter long.
• 8-Foot Length: Perfect for lining the perimeter of rectangular or oval pools.
• Double-Tubed Stability: Prevents rolling and ensures the bag stays exactly where you place it.

Pro Tip: Only fill waterbags halfway to three-quarters full. This allows for water expansion when the bag freezes, preventing the vinyl from bursting.
