This is an Anti-Electrolysis Zinc Anode Replacement Kit when you need to replace your inline Anti-Electrolysis Zinc Anode by Pool Tool. The kit includes zinc anode, thru rod, new cap, and o-ring.
The Zinc Anode will sacrifice itself and corrode before all other metals in the pool. In doing so, the anode protects other metal parts from galvanic corrosion. The Zinc Anode will need to be replaced approximately every three (3) years or when it is 1/2 its original size.
The inline zinc anode is attached to the bonding wire thereby protecting all metal parts against the effects of galvanic corrosion. The see through housing allows the anode to be easily replaced when depleted. No re-plumbing required. A must for salt water pools.
