Product Description 8 inch double chamber water tubes are constructed of heavy-duty 16 gauge, puncture resistant vinyl. All of our water tubes have a conveniently placed, leak-proof valve that is easy to fill with a garden trousers. 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 Do not overfill water tubes to prevent expansion and popping when frozen.
