Product Description
The AO SMITH 100110627 is a flexible plug anode rod designed to protect residential water heater tanks from corrosion. Constructed from aluminum, this sacrificial anode rod works by attracting corrosive elements in the water, slowing tank wall degradation over time. At 33 inches in length with a 3/4-inch hex plug connection, the flexible design allows installation in water heaters where overhead clearance is limited, making service calls in tight utility spaces more manageable. It is installed by licensed plumbers and qualified service technicians during routine water heater maintenance or anode replacement intervals.
This anode rod is suited for residential water heater applications where the existing anode has depleted and requires replacement. The 3/4-inch hex end type matches the standard magnesium and aluminum anode port found on many storage-tank water heaters. Its flexible construction is particularly useful in attic installations, closet installations, and other confined spaces where a rigid rod cannot be threaded out without obstruction. Always verify port size and thread pitch before ordering.
Key Features
- Aluminum construction provides sacrificial corrosion protection for water heater tank interiors
- 33-inch length suits full-size residential storage water heaters
- 3/4-inch hex plug connection matches standard anode ports
- Flexible design enables installation and removal in low-clearance spaces
- Direct replacement part for water heater anode service
Compatibility
Designed as an OEM-style replacement anode rod for residential storage-tank water heaters equipped with a 3/4-inch hex anode port. Verify thread pitch and port diameter against the existing anode before installation.
Installation Notes
Installation is typically performed by a licensed plumber. Before servicing, shut off the cold water supply and disconnect power to electric units or set gas control to pilot on gas units, and allow the tank to cool. A 1-1/16-inch socket and breaker bar or impact wrench are commonly used to break loose the anode plug. Drain a few gallons from the tank to relieve pressure before removal, and apply thread sealant tape to the new anode threads prior to reinstallation.
