Buffalo Blizzard Blue Heavy Duty 16-Gauge Single Chamber Water Bag, 4 ft, 18 Pack

Buffalo Blizzard Water bags are the best way to keep your swimming pool's winter cover secure during the colder months. This single chamber water bag lays flat on top of the winter cover and reduces the risk of the water bag rolling once frozen. It also works great to hold on leaf net for swimming pool. Manufactured from high quality vinyl, it has been designed to withstand sub-zero temperatures and has been treated with antibacterial & anti-fungal additives, as well as UV inhibitors to prevent fading. All water bags come with a leak-proof valve that is conveniently placed for ease of filling with a garden hose.

Instructions:

Once you have your winter cover in place, slide these bags through your cover’s water bag loops before filling them with water. Fill water bags 1/2 to 3/4 full to allow room for expansion due to freezing. If you are having trouble closing the valves on your water bags - try this trick! Soak them in warm water and they will close easily.
