Hinsperger WB8DD Double-Chamber Water Bag / Winter Cover Tube (12″ × 96″)
The Hinsperger WB8DD is a heavy-duty, double-chamber water bag designed to secure winter pool covers on in-ground or above-ground pools. It helps keep the cover tight and stable during winter by adding weight, preventing movement from wind, debris, or water accumulation — and reducing stress on the cover and anchor points.
Key Features
- Double-chamber “water-tube” construction — two internal chambers share a single valve, distributing weight evenly for balanced cover tension.
- Size: 12″ wide × 96″ long — suitable for medium to large pool cover edges or as part of a cover-weighted system.
- Made from heavy-gauge, UV-treated U.S. vinyl for durability and long service life.
- Large reinforced valve for easy fill and secure sealing that resists leaks or slow drainage.
- Freeze-crack additive in vinyl and thicker gauge help resist cold-weather damage, extending winter cover reliability.

Why Use WB8DD
Using water bags like the WB8DD is one of the most effective and affordable ways to secure a pool cover for winter. The double-chamber design ensures even weighting, which helps prevent cover shifting, debris build-up under the cover, and potential damage from wind or rain. Its robust vinyl and freeze-resistant build make it a dependable winter maintenance tool for pool owners.
Installation & Maintenance Tips
- Slide the partially filled water bag under the pool cover at the edge; once positioned, finish filling the bag via garden hose until both chambers are full and heavy.
- Place enough bags around the cover perimeter according to cover size and pool shape — usually spaced every 2–3 feet for proper weight distribution.
- Check and top off water levels in the bags periodically through winter if freeze-thaw cycles or evaporation occur to maintain cover tension.
- Before spring opening, remove all water bags, drain, rinse, and store them dry to prolong vinyl life and prepare for next season’s use.
