Product Description 8' Double Chamber Black Water Tubes are constructed of heavy-duty, puncture resistant vinyl. All of our water tubes have a conveniently placed, leak-proof valve that is easy to fill with a garden hose. Water tubes keep your pool cover in place all winter long. Water tubes should be filled half-way to prevent popping caused by expansion if the water freezes. Safety Warning Handle with care during installation, use, and removal. Always secure the pool cover properly to prevent drowning hazards.
