Lochinvar & A.O. Smith 100187890 Anode 328140-751 the gas valve itself remainsThe Lochinvar & A. O. Smith 100187890 Anode is a heavy duty, 19. 69" powered anode designed for high demand commercial and residential water heating systems. Unlike standard sacrificial rods, this titanium powered anode utilizes impressed current cathodic protection to actively neutralize corrosive elements within the tank. By delivering a continuous, low voltage electrical current, it creates a protective barrier that stops the oxidation of the steel
