Product Description
The AO SMITH 100210012 is a powered anode rod designed to protect water heater tanks from corrosion through an impressed-current electrochemical process. Unlike sacrificial magnesium or aluminum anodes that deplete over time, a powered anode uses a low-level electrical current to suppress corrosion activity on the tank lining. This rod measures 0.118 inches in diameter and 7.87 inches in length with a hex end type for straightforward installation. Plumbers and water heater service technicians install this component as a direct replacement in compatible residential water heater tanks where the original anode has been removed or where a maintenance-free corrosion protection solution is required.
This powered anode rod is suited for residential water heater applications where tank longevity is a priority. It is particularly useful in homes with soft or treated water, which tends to accelerate sacrificial anode depletion. The compact 0.118-inch diameter and 7.87-inch length make it appropriate for water heater tanks with limited port clearance. It installs as a replacement part and is intended for use by licensed plumbers or experienced service technicians performing routine water heater maintenance or anode replacement service calls.
Key Features
- Powered anode design uses impressed current rather than sacrificial metal to protect tank from corrosion
- 0.118-inch diameter fits tanks with restricted anode port access
- 7.87-inch length suits standard residential water heater configurations
- Hex end type allows installation and removal with standard socket tools
- Maintenance-free operation compared to traditional sacrificial anode rods
Compatibility
Designed as an OEM-style replacement powered anode rod for residential water heater tanks requiring a 0.118-inch diameter, 7.87-inch hex-end anode port.
Installation Notes
Installation should be performed by a licensed plumber or qualified water heater service technician. Before servicing, shut off the cold water supply and disconnect electrical power or close the gas supply valve to the water heater. Use a socket wrench sized to the hex fitting to remove the existing anode and install the replacement. Follow all applicable local plumbing codes and the water heater manufacturer guidelines when connecting the powered anode lead wire.
