Blue Wave Double Water Tubes, 10-ft 5-Pack for Winter Pool Covers

Blue Wave Double Water Tubes anchor in-ground pool covers for winter, with 18-gauge puncture-resistant vinyl and two independent chambers in each tube.

• Five tubes, each 10 ft (3.05 m) long — plan pool-edge coverage in manageable sections.
• Withstands -10°F (-25°C) to 180°F (80°C) — made for exposure to winter cold and summer heat.
• Flexible tubes fit rectangular, kidney-shaped, and freeform edges — use with several types of pool covers and nets.
• Fills with a standard garden hose and drains without a pump — prepare the tubes for seasonal use and storage.
• Connect tubes end-to-end — cover the pool perimeter with adjoining lengths.

Winter wind can lift or shift an in-ground pool cover, while leaves and other debris collect on its surface. Blue Wave water tubes add weight along the pool edge to help keep the cover in place through the off-season. Securing a cover also helps reduce the risk of slips and accidental falls around the pool area.

How do the tubes help keep a winter pool cover in place?

Each tube holds water to weigh down the cover edge and resist wind lift and shifting. Its two independent chambers distribute weight along the pool perimeter; if one chamber is punctured, the other can continue holding the cover in place. The 18-gauge vinyl is puncture-resistant, and reinforced seams are designed for exposure to harsh seasonal conditions.

• Blue PVC construction withstands temperatures from -10°F (-25°C) to 180°F (80°C).
• Fill each tube to three-quarters full to leave room for water expansion if it freezes.
• Blue Wave includes a 90-day limited warranty; the brand has more than 35 years of pool-industry experience and U.S.-based support.

Will these water tubes fit my pool shape and cover?

Yes. The flexible tubes curve around rectangular, kidney-shaped, and freeform pool edges, and work with solid, mesh, and hybrid covers. They can also weigh down leaf nets and summer pool covers. For perimeter planning, divide the pool’s perimeter or circumference in feet by 10; connect the tubes end-to-end for continuous coverage. Each tube covers up to 10 ft (3.05 m).

• The five-tube set provides separate lengths to position around the pool edge.
• Use the same perimeter calculation whether the pool is measured by perimeter or circumference.
• Position adjoining tubes end-to-end to help avoid uncovered gaps along the edge.

How do you fill and store the tubes?

Connect a standard garden hose to the oversized, leak-resistant valve to fill a tube, then secure its push-in plug cap. The valve and cap are designed to keep water contained during use. When the season ends, open the valve and tip out the water; no pump is needed to drain the tubes.

• Allow space inside each tube for freezing-water expansion by filling it only three-quarters full.
• After draining, store the tubes flat until the next pool-cover season.
• Reinforced, leak-resistant valve details support filling and closing the tubes for use.

How many tubes are needed for the pool perimeter?

Use the pool’s perimeter or circumference in feet and divide by 10 to estimate the number of tubes. Each 10-ft (3.05 m) tube covers up to 10 ft (3.05 m) of pool edge, and the tubes can be connected end-to-end. This calculation helps you plan coverage for the pool’s full outline.

• Measure the full pool perimeter or circumference in feet before planning tube placement.
• Use the calculated tube count to map out end-to-end coverage around the edge.

These Blue Wave tubes suit pool owners securing an in-ground pool cover, leaf net, or summer cover along a straight or curved edge. They are made for weighing down pool coverings around the perimeter, rather than for use as a cover themselves. With flexible, water-filled lengths and a pump-free drain-down process, they provide a practical seasonal anchoring option.
