Yankee Pool Pillow Corner Water Tubes for Rectangular In-Ground Covers, 23.6×11.8 in Heavy-Duty 0.4mm PVC, Cold-Resistant

Yankee Pool Weights are heavy-duty corner water tubes designed to anchor rectangular in-ground pool covers securely through winter using durable 0.4 mm PVC and leakproof valves.

When winter arrives, a reliable way to keep your pool cover taut and safe is essential. These corner water bags measure 23.6" x 11.8" and are built from thick 0.4 mm (27-gauge) PVC that resists cold down to about -10°F (-23°C). Tested for safety and manufactured with airtight seals and wide-fill valves, they’re created to simplify installation and minimize maintenance while protecting your pool through the off-season.

How do these weights hold a rectangular in-ground cover in place?

The weights use water ballast to add mass along the corners and edges of a rectangular pool cover, preventing wind lift and shifting. Their shape and size optimize contact with cover material so the cover remains level and protected.

• Fill with garden hose using wide valve openings for fast water intake.
• Mass distribution from water prevents wind from blowing the cover loose.
• Designed to sit flat at corners and along straight cover seams.

Are these pool cover bags durable in cold climates?

Yes—manufactured from 0.4 mm (27-gauge) PVC, these tubes withstand winter temperatures down to about -10°F (-23°C) without becoming brittle. Their construction and reinforced seals resist punctures and cracking that can occur with thinner materials.

• Heavy-duty PVC resists tears and abrasion.
• Cold-resistant rating suitable for harsh winters.
• Reinforced seams and robust material extend service life.

How do I fill and seal these water bags without leaks?

Each tube features an extra-wide valve engineered for quick filling with a standard garden hose and a grippy, leakproof twist cap that secures tight closure—no snap caps that fail over time. The airtight sealing technology keeps water inside until you intentionally empty them.

• Wide-funnel valves speed up filling and reduce spillage.
• Threaded, grippy twist caps prevent accidental openings and leaks.
• Lab-tested airtight seals ensure season-long performance.

Are these safe for families and pets around the pool area?

Safety was part of the product design: the materials are US CPSIA compliant and were evaluated by an accredited lab for harmful substances. That reduces concerns about toxic chemicals or dangerous metals in the material touching your pool cover or yard.

• CPSIA-compliant materials tested by an accredited laboratory.
• No known harmful metals or banned chemicals used in production.
• Rounded corners and low profile limit tripping hazards when placed properly.

Who is this for? Homeowners who winterize in-ground rectangular pools and want a low-effort, rugged solution to secure covers will appreciate these Yankee Pool Weights. They're especially useful for people living in colder climates, those who prefer quick hose-fill installation, and anyone who values tested materials and sturdy, leakproof construction for season-long protection.
