Why choose a single-chamber water tube over a double-chamber water tube, and what are the advantages of a single-chamber water tube?

1. Unlike traditional double-chamber tubes that require precise filling and constant adjustments, our single-chamber design streamlines the entire process, allowing you to spend less time prepping. Just fill the tube once, and you’re done—no need to worry about uneven distribution or leaks between chambers.
2. These tubes are also virtually seamless which means there will be less chance of the tubes failing and leaking at the seams, as most of the leaks occur at the seams(Dual-chamber water bags have more seams). The simplicity of a single chamber eliminates the risk of leaks between compartments, offering peace of mind that your pool is fully protected.
3. Our single-chamber water bag outperforms traditional dual-chamber ones with its higher capacity, providing extra weight and pressure to keep pool cover tubes flat and secure. This ensures a tighter seal, preventing wind, rain, and snow from slipping under and causing damage, even in harsh weather conditions.

These tubes are very sturdy and maintain a much more defined shape which helps seal the edges of the cover than thinner 0.4mm 1-layer PVC tubes.

• The upper/lower layers are crafted with premium E-PVC, ensuring exceptional resistance to cold temperatures, cracking, and wear. The fiber explosion-proof middle layer adds superior strength and durability, preventing punctures and leaks.
• Our top-tier composite material isn’t just tough—it’s practically indestructible. Offering more than triple the leak protection of standard single-layer PVC, it’s built to handle the harshest conditions. When water freezes inside the bag during winter, it stands up to the challenge, resisting expansion and keeping everything secure.

Ultrasonic welding is faster, more energy-efficient, creates less heat damage, offers precise welds, and doesn't require formaldehyde-based adhesives.

• Strong, Precise Seams: Ultrasonic welding ensures tight, durable seams that prevent leaks.
• No Adhesives: The process eliminates the need for harmful adhesives.
• Durable for Winter: Provides long-lasting protection against cold weather.
• Smooth, Clean Finish: Delivers a high-quality, neat finish that resists wear and tear.

The screw caps are a nice feature to make these pool water tubes easy to fill and empty.

• The best feature is the screw on filler cap. Most water caps are snap-on, making it difficult to close while keeping all the water inside. The screw caps are much more user friendly and convenient to use. They have a rubber seal on the inside to keep the water from leaking out of the bags.
• Compared to screw caps with rubber sealing rings, other styles of water caps (such as snap-on) are difficult to tighten. When you try to tighten them, water will spray out, leaving you soaked.
• The screw caps also has a long service life and stronger water pressure resistance. It won't experience reduced sealing effectiveness and leakage like snap-on caps do after prolonged use, or leak due to increased water pressure caused by freezing and expansion of the water inside the bag during winter.

The compressive strength is so strong that it can pass the car run-over test

• Due to the utilization of the most advanced welding technology, high-quality composite materials, and the excellent sealing properties of the screw cap, our water tube can withstand the test of being run over by a car. No other similar product on the market has been able to pass the car run-over test.

The water tubes could be positioned along a curve.

• Versatile coverage along curves for flexible pool edge protection.
• Overcome design limits, ensuring optimal winter pool cover protection.
• Achieve optimal coverage around pool edges, a feat impossible with the external design limitations of double-chamber water bags.
