The one-way winter valve for winterizing pools is the perfect match for those who use the Aquador skimmer cover when closing the pool. Snap on your Aquador, then screw the one-way blow-out plug into your wall return. Add antifreeze into the return lines, or use air from a blower box or a compressor, at a low air pressure setting. The one-way winter pool valve will allow the water to be blown out of the line, without allowing any water to come back into the line.
Commonly known as a blow-out plug for pool winterizing, the one-way winter pool valve completely eliminates the need for rubber pool return plugs or freeze plugs when winterizing your pool. Much better constructed than a winter duck plug – our one-way pool plug keeps water out, and you can count on its performance year after year.
Did you know that some people, when closing their pool, actually lower the water level below the returns, plug the lines, and then fill the pool back up? Our unique one-way winterizing valve saves time and water. Recommended by pool professionals in the know – prevents worry about water in the lines freezing, when you close the pool with our one-way winter pool plug.
Pool freeze plugs, made of rubber, last only a few years before they dry-rot and crack. Our threaded blow-out plug inserts easily into your wall returns and pool cleaner fittings (1.5" threaded), and seals up tight with a durable Buna-N o-ring. Winter duck plugs have a rubber seal that can open during winter, and a flimsy plastic cap that easily get misplaced during summer.
Easy to use, long lasting and snug fitting, there is no better winter pool plug available. Can be used on both inground and aboveground pools.
