Lochinvar & A.O. Smith 100108660 Anode
For service technicians and building maintenance managers, the Lochinvar & A.O. Smith 100108660 is the direct OEM replacement magnesium sacrificial anode rod engineered to mitigate tank electrolysis. This 32-inch water heater anode rod features a high-purity magnesium construction with a 0.84-inch diameter, providing a higher voltage output compared to aluminum alternatives. This makes it the preferred choice for soft water applications where aggressive corrosion is a risk. Designed with a standard 3/4" NPT connection, this rod integrates seamlessly into a wide range of Lochinvar and A.O. Smith residential and commercial tanks. Replacing a depleted 100108660 magnesium anode is a critical maintenance step to prevent hydrogen gas buildup and localized pitting on the tank interior. Utilizing a genuine Lochinvar replacement part ensures thread compatibility and maintains the original equipment’s engineering specifications for cathodic protection and sediment control.
Key Benefits for Professionals:
- High-Output Magnesium: Provides superior electrochemical protection in soft water to neutralize corrosive elements before they attack the steel tank.
- OEM Dimensional Accuracy: The 32" length and 0.84" diameter ensure proper clearance and maximum surface area for effective ion exchange.
- Standardized Threading: The 3/4" NPT threads allow for straightforward installation with standard 1-1/16" sockets.
- Corrosion Mitigation: Acts as the primary defense against tank wall thinning and premature failure in high-demand HVACR environments.
Common Questions from the Field:
When should this 100108660 anode rod be replaced?
Inspect the rod during annual maintenance; if more than six inches of the core wire is exposed or if the diameter has depleted by 50%, a replacement is necessary.
Why choose magnesium over aluminum for A.O. Smith tanks?
Magnesium is more reactive and provides better protection in soft water environments, though it should be avoided if a strong sulfur odor is already present in the hot water system.
Is this compatible with commercial Lochinvar units?
Use this rod for any unit specifying part #100108660; always verify the overhead clearance is at least 32 inches before attempting installation.
