Extra-large water capacity: Elevate your pool protection with our 13" x 13" black water bags, guaranteeing superior pressure and a tighter seal than the competition's 11.5" x 11.5". Designed for maximum water capacity, these heavy-duty bags provide unrivaled stability and weight when filled, ensuring your pool cover stays put even in the fiercest winter winds and snow.
Effortless Setup: Equipped with handles for easy fill, move, and install actions, and a strategically placed filling cap on the upper left to prevent leaks. Once hung, the top cap design ensures zero leakage, even if it loosens, freeing you from the hassle of winter refills or reinstallations due to cap malfunctions. Secure your pool cover all winter long with confidence and ease.
Triple-Layer Composite Construction: Our water bag features a robust three-layer composite design, measuring 0.7mm in thickness, with a convenient pack of 8. It is constructed with E-PVC on both the outer layers and incorporates a fiber-reinforced middle layer for enhanced safety. In contrast to weaker 0.4mm PVC options, our bags offer superior resistance to UV rays and aging. They remain intact and resilient, even when water freezes, guaranteeing long-lasting performance and dependability.
High-frequency welding: Utilizing high-frequency welding with wide seams, our water bags ensure exceptional airtightness and resist high pressure. Withstanding temperatures as low as -10°F (-25°C), fill them 3/4 full to prevent breakage from freezing expansion. Experience durability for over 2 years in low temperatures.
Screw Tops: A great feature is the screw on filler cap. Most water bags have snap-on style water filling caps, which are difficult to close while keeping all the water inside the bag. The screw caps are much more user friendly and convenient to use. They have a rubber seal on the inside to keep the water from leaking out of the bags.
