One-Way Winter Pool Valve for Inground Pools

No More Draining your Pool for the Winter! Our specially designed One-Way Pool Valve is a real time-saver during winter pool closing. It prevents pool water from entering the return lines while you winterize - without having to drain the pool. Simply replace the current "eyeball" return fitting with this new winterizing Valve. Then drain the water inside the plumbing lines, fill them with Pool Antifreeze and you'll successfully keep water from re-entering the line during the off-season.
