The Rheem-Ruud AP18572 Powered Anode Rod (0.500" Diameter x 44" Long) is a corrosion protection component designed to extend the service life of compatible water heaters by preventing tank deterioration. Unlike traditional sacrificial anode rods, it uses a low-voltage electrical current to neutralize corrosive elements in the water, reducing tank corrosion without being consumed over time. Commonly used in Rheem and Ruud residential and commercial water heating systems, this powered anode rod enhances equipment durability, minimizes maintenance, reduces odor caused by certain water conditions, and helps maintain reliable, long-lasting water heater performance.
