2″ Inline Zinc Anode

The Pool Tool 2″ Inline Anti-Electrolysis Zinc Anode (104-C2) is an essential protective component designed to shield your pool’s metal equipment from the damaging effects of galvanic corrosion. Specifically engineered for 2-inch plumbing, this sacrificial anode proactively corrodes to neutralize electrical currents, preventing the pitting and erosion of expensive heaters, pool lights, rails, and pump seals. It is considered a “must-have” for saltwater pool systems, where high salt levels increase the rate of electrolysis. The unit features a see-through housing for effortless monitoring, allowing you to visually inspect the zinc rod and replace it only when necessary, typically every 3 to 5 years.
