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