Blue Wave 10-ft Double Water Tube for Winter Pool Cover - 5 Pack

The Blue Wave 10-ft Double Water Tube for Winter Pool Cover is designed to secure a winter cover on inground or above ground pools. These tubes are filled with water, not air, and are meant to be heavy to keep the cover in place. Although the product has a competitive price, there have been multiple complaints of leaks and difficulties in sealing the fill cap. Some customers have also noted that the plastic used in these tubes is thinner compared to other brands. It is important to consider these factors before purchasing.
