Blue Wave 8-ft Double Water Tubes, 5-Pack for Winter Pool Covers with Dual Chambers

Blue Wave 8-ft Double Water Tubes are a five-pack of flexible, dual-chamber pool weights designed to anchor in-ground winter covers, with puncture-resistant 18-gauge vinyl for seasonal use.

• Five 8-ft (2.44 m) tubes — provides water-filled weights to secure an in-ground pool cover.
• 18-gauge puncture-resistant vinyl — made to withstand temperatures from -10°F (-25°C) to 180°F (80°C).
• Two independent chambers per tube — the second chamber can continue holding the cover if one is punctured.
• Flexible construction for different pool shapes and cover types — bends around pool edges and also weighs down leaf nets and summer covers.
• Garden-hose valve and drainable design — fill with a standard hose, then empty without a pump for flat storage.

Wind can lift a winter pool cover, while rain and fallen debris can contribute to shifting around the pool edge. Blue Wave water tubes add weight along the perimeter to help hold an in-ground cover in place through the off-season. Their flexible shape suits straight and curved pool edges, making them useful for kidney-shaped, freeform and rectangular pools.

What are Blue Wave double water tubes designed to do?

They anchor in-ground pool covers by spreading water weight along the pool edge. A securely held cover resists wind lift and shifting, helping limit debris buildup and reducing the risk of slips and accidental falls around the pool area. The tubes can also be used to weigh down leaf nets and summer pool covers.

• Useful for solid, mesh and hybrid pool covers.
• Designed to help keep covers in place during wind, rain and debris accumulation.

How do I choose enough tubes for my pool?

Use the pool’s perimeter or circumference in feet to estimate the number required: divide that measurement by 8. Each tube covers up to 8 ft (2.44 m) of pool perimeter, and the five-pack contains five tubes. Arrange them end-to-end for coverage around the pool edge; the flexible design curves to follow kidney-shaped, freeform or rectangular pools.

• Compare your pool’s perimeter with the coverage of one tube.
• Connect tubes end-to-end to cover the required edge length.

Good to know: the coverage needed depends on the pool perimeter, so use that measurement when deciding how many tubes are needed.

How do the tubes fill, and how should I store them?

Connect a standard garden hose to the oversized valve to fill each tube, then secure the push-in plug cap. Fill each tube to three-quarters full, leaving room for water expansion if it freezes. When the swimming season returns, open the valve to drain the tubes; no pump is needed, and they can be tipped out and stored flat.

• Reinforced valves are designed for filling and a leak-resistant seal.
• The three-quarter fill level leaves space for freezing-water expansion.

What construction and warranty does this five-pack have?

Each tube is made from blue PVC with puncture-resistant 18-gauge vinyl and reinforced seams. The material is designed to withstand temperatures from -10°F (-25°C) to 180°F (80°C) without cracking or stiffening. Two independent chambers distribute the water weight; if one chamber is compromised, the other can continue to help anchor the cover.

• Blue Wave includes a 90-day limited warranty.
• Blue Wave has over 35 years of experience in the pool industry and U.S.-based support.

This five-pack suits pool owners securing in-ground covers around seasonal pools, including curved pool shapes and solid, mesh or hybrid covers. Its defining fit is flexible, water-filled perimeter coverage supported by a dual-chamber design and drainable construction.
