Pool cover water bags are a great way to keep your winter pool cover in place throughout the season. With double chambers, these pool cover water tubes are constructed of a heavy-duty vinyl that is 35% heavier than other water bags, and have much more puncture resistance as well. Double chambers are optimal in case one chamber breaks, there is still enough weight in the water tube’s other chamber to help keep the cover in place.read more
The double pool cover water bags are easy to fill with a unique valve that locks on to a garden hose during filling. Fill the water bags about half way to two-thirds full, allowing room for ice to expand during the winter. Place pool cover water bags end to end on your winter cover along your pool, overlapping the bags in places where the pool cover covers less than two feet of your deck.
