Ao Smith 100109624 Aluminum Anode Rod 16 in 3/4 Npt

Product Description

The AO SMITH 100109624 is a 16-inch aluminum anode rod designed to protect water heater tanks from corrosion. Anode rods work through sacrificial electrochemical action, corroding in place of the steel tank lining to extend tank service life. This rod measures 16 inches in length and connects via a 3/4-inch NPT hex-end fitting, making installation straightforward with standard tools. It is a direct replacement part intended for residential and light commercial water heater service. Plumbers and water heater technicians install anode rods as part of routine maintenance or warranty-related repairs.

This anode rod is suited for use in storage-type water heaters that accept a 3/4-inch NPT threaded anode port. Aluminum anode rods are commonly specified in areas with soft water or where magnesium rods have caused odor issues. The 16-inch length fits a range of standard tank configurations. It is installed as a replacement part during scheduled water heater maintenance intervals or when the existing rod has been depleted.

Installation Notes

Installation should be performed by a licensed plumber or qualified water heater technician. Before removing or replacing an anode rod, shut off the cold-water supply and relieve tank pressure at a hot-side faucet. A 1-1/16-inch socket and breaker bar or impact wrench are typically required to break loose the existing rod. Follow all applicable local plumbing codes and the water heater manufacturer guidelines when servicing the anode port.
