Protect your pool or spa equipment from corrosion with this SOLAXX REG20A inline sacrificial anode. It's a zinc anode already secured inside a PVC fitting, ready for installation into your saltwater pool or spa's plumbing. How it works: the zinc anode corrodes first (it's 'sacrificial'), which helps prevent your more expensive metal components—like heaters, pumps, and ladders—from rusting and deteriorating. Easy to install and replace when depleted. A simple, cost-effective way to extend the life of your pool equipment and keep everything running smoothly. A must-have for saltwater pool owners.
