Pool Cover Water Bags Set, 6 Packs 8 Ft Single Chamber Pool Cover Water Bags & 4 Corner Tubes, 0.4mm Thick PVC Bag Weights with Leakproof Valve, for Winter Inground Swimming-Pool Covers

6 Pack Single-Chamber Pool Cover Water Bags

Each 8ft x 0.77ft winter pool water tube is built to withstand tough winter conditions. Designed to securely anchor your pool cover, it helps keep out leaves and debris—minimizing cleanup and keeping your pool clean all season.

Crafted from heavy-duty PVC, the pool cover water tubes are tear-resistant and built to last. Once filled, they provide reliable weight without cracking or tearing, even after repeated use—perfect for long-term outdoor setups.

The inground pool cover water bag features a threaded twist cap for secure, leak-proof sealing and a wide opening compatible with most garden hoses for easy filling. Reinforced with 0.59-in high-frequency welded seams to minimize leakage. The single-chamber design boosts filling efficiency.

When installing, ensure the retaining ring is fully pushed to the base of the spiral threads. Improper positioning (middle or top) may lead to leakage or bag shifting once filled.

Engineered to withstand all climates, the single chamber water tubes for pool cover won’t crack under sun or harden in cold. Whether it’s spring, summer, fall, or winter, your pool stays protected and clean year-round.
