Product Description 10’ Double Chamber Blue Water Tubes are constructed of heavy-duty 20 gauge, 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 Potential drowning hazard if not properly secured. Fill water tubes halfway to allow for ice expansion. Use caution when handling and securing the pool cover.
