The POOL TOOL 104R-KIT is an inline zinc anode replacement kit designed to protect pool equipment and metal fittings from galvanic corrosion and stray electrical current damage. Zinc anodes work through sacrificial corrosion - the zinc degrades preferentially, drawing electrochemical activity away from more critical metal components in the system. This kit is installed directly in a pool's plumbing line and is serviced by pool technicians and plumbing professionals performing routine corrosion-control maintenance. The anode body measures 0.98 inches x 0.98 inches x 0.98 inches and is constructed from zinc.
This replacement kit is suited for residential and light commercial pool systems where anti-electrolysis protection is part of a standard maintenance program. Inline anode installations are common in pools with mixed-metal plumbing, pools located near electrical infrastructure, or any system where galvanic corrosion has been identified as a recurring issue. The compact form factor fits into existing inline anode housings, making it a direct drop-in service replacement.
Designed as an OEM-style replacement anode for POOL TOOL inline zinc anode assemblies used in residential and light commercial pool plumbing systems.
Installation is typically performed by a licensed pool technician or plumbing professional. Before servicing, shut off the circulation pump and relieve any line pressure to avoid leaks during disassembly. Inspect the anode housing for wear or scale buildup before inserting the replacement anode. Follow all applicable local plumbing codes and the equipment manufacturer guidelines when reassembling the inline housing.
