ELIMINATES THE NEED TO DRAIN WATER WHEN WINTERIZING YOUR IN-GROUND SWIMMING POOL!
- This pool valve prevents water from entering the return lines with a unique one-way valve system.
- Simply replace your current "eyeball" return fitting with this valve when winterizing, drain the water from the lines, fill with antifreeze and water is prevented from re-entering the lines.
- Valve can be installed without ever having to drain your pool!
