The Pool Tool Replacement Zinc Anode Kit (104R-KIT) is the essential maintenance component designed specifically for the 104-D Inline Zinc Anode housing. Over time, the sacrificial zinc rod in your inline unit naturally erodes as it protects your pool’s heater, lights, and pump seals from galvanic corrosion and electrolysis. This kit allows you to restore full protection to your saltwater or chlorine pool without replacing the entire plumbing fixture. Each kit includes a high-purity replacement zinc rod, a new clear plug for easy visual monitoring, and a fresh O-ring to ensure a perfectly watertight seal. By simply unscrewing the old plug and installing the 104R-KIT, you ensure your pool’s metal components remain shielded from the pitting and staining caused by electrical currents in the water.
