Pool Tool 104R-KIT Inline Zinc Anode Replacement Kit
The Pool Tool 104R-KIT is a replacement zinc anode kit designed to protect pool and spa metal components from galvanic corrosion. The kit restores a sacrificial anode system — the zinc anode corrodes in place of more critical metal fittings (pumps, heaters, heaters, lights, etc.), helping extend their lifespan.
Key Features
- High-purity zinc anode — sacrificial metal that corrodes first, safeguarding plumbing and equipment metallurgy.
- Complete kit — includes zinc anode rod, thru-rod, O-ring, and replacement cap for easy installation.
- Inline installation — integrates into existing pool or spa plumbing systems with anode housings, providing passive corrosion protection.
- Ideal for saltwater pools or systems with high mineral/chemical content — reduces risk of metal degradation over time.
Specifications
- Manufacturer: Pool Tool
- Part Number: 104R-KIT
- Included Components: Zinc anode rod, thru-rod, O-ring, replacement cap
- Application: Sacrificial anode for pool/spa plumbing — protects pumps, heaters, lights, metal fittings
- Recommended Replacement: Roughly every 2–3 years, or when the anode is reduced to ~50% of its original size
When & Why to Replace
Use 104R-KIT when the existing zinc anode is depleted, or as part of regular maintenance on saltwater or mineral-heavy pools. Replacing the anode helps prevent corrosion-related failures in expensive pool equipment and plumbing — an inexpensive way to extend the life of the system and avoid costly repairs down the line.
Installation & Maintenance Tips
- Turn off the pump and depressurize the system before servicing the anode housing.
- Remove old anode rod, clean the housing interior, then install the new 104R-KIT components — seat the O-ring and secure the cap to ensure a tight seal.
- Check the anode rod annually; replace when visibly corroded or worn to less than half original size.
- After replacement, monitor system water chemistry — maintain proper balance to reduce corrosion rate and maximize anode life.
