Ao Smith 100111073 Aluminum Zinc Anode Rod 16 in

Product Description

The AO SMITH 100111073 is a 16-inch universal aluminum/zinc anode rod designed to protect water heater tanks from corrosion. The anode rod works through a sacrificial electrochemical process, corroding in place of the steel tank lining to extend the service life of the water heater. At 0.75 inches in diameter with a 3/4-inch NPT hex-end connection, this rod installs directly into the anode port on most standard tank-style water heaters. Licensed plumbers and water heater service technicians install this part during routine maintenance or when an existing anode rod is depleted.

This anode rod is suited for residential and light commercial tank-style water heaters that use a standard 3/4-inch NPT anode port. The aluminum/zinc alloy composition makes it appropriate for installations where water conditions cause accelerated corrosion or where sulfur odor is a concern. The 16-inch length fits a range of water heater tank sizes where a shorter anode is required or where overhead clearance limits the use of full-length rods.

Key Features

• Aluminum/zinc alloy construction provides sacrificial corrosion protection for steel tank liners
• 16-inch length suits water heaters with limited overhead clearance or compact tank designs
• 0.75-inch diameter with 3/4-inch NPT hex-end connection for straightforward installation
• Universal fit designed for use across a wide range of tank-style water heater configurations

Compatibility

Designed as a universal OEM-style replacement anode rod for tank-style water heaters equipped with a 3/4-inch NPT anode port.

Installation Notes

A licensed plumber or qualified water heater technician should install this anode rod. Before servicing, shut off the cold water supply and disconnect power or close the gas valve to the water heater. A 1-1/16-inch socket and breaker bar are typically required to remove and install the anode rod. Follow all applicable local plumbing codes during installation.
