A.o. Smith 100108260 Aluminum Anode Rod 29 Inch

Product Description

The A.O. SMITH 100108260 is a standard aluminum anode rod designed to protect water heater tank linings from corrosion through sacrificial electrochemical action. Measuring 0.75 inches in diameter and 29 inches in length, this rod is threaded with a 3/4-inch hex-end connection for straightforward installation and removal. Aluminum construction makes it suitable for water supplies where magnesium rods are less effective, including softened or treated water. Licensed plumbers and water heater service technicians install this rod as part of routine water heater maintenance to extend tank service life.

This anode rod is intended for use in residential and light commercial storage-tank water heaters requiring a 3/4-inch hex-connection replacement rod. It is a direct replacement part suited to standard tank configurations where a 29-inch rod length is specified. The rod is installed vertically inside the tank and degrades over time in place of the tank wall, making periodic inspection and replacement a standard service procedure.

Key Features

• Aluminum material provides sacrificial corrosion protection for the water heater tank interior
• 0.75-inch diameter rod, 29 inches in length for compatibility with standard tank configurations
• 3/4-inch hex end connection allows removal and installation with a standard socket wrench
• Drop-in replacement part designed to meet OEM-style fitment requirements
• Suitable for use in softened or chemically treated water supplies where aluminum outperforms magnesium

Compatibility

Designed as an OEM-style replacement anode rod for residential and light commercial storage-tank water heaters requiring a 3/4-inch hex-end connection and a 29-inch rod length.

Installation Notes

Anode rod replacement is typically performed by a licensed plumber. Before servicing, shut off the cold water supply and disconnect power to the water heater, or turn off the gas supply at the shutoff valve. Relieve tank pressure at the temperature and pressure relief valve before loosening the anode rod fitting. A breaker bar or impact wrench is commonly required to break loose a corroded rod, and thread sealant tape should be applied to the hex fitting threads on reinstallation.
