Abstract
The present invention provides a sacrificial anodic plug for insertion within an irrigation span to provide anodic corrosion protection. According to a preferred embodiment, the anodic plug of the present invention includes a protective cap connected to a securing bushing, and an anodic coupler which extends into the interior of the irrigation span. Preferably, the securing bushing includes non-conductive threads for mating with the threads of a sprinkler outlet and for electrically isolating the anodic coupler from the protective cap. According to further preferred embodiments, the anodic coupler is formed of magnesium and extends down away from the protective cap and terminates in an anodic base. According to a further preferred embodiment, the protective cap may include a wear indicator indicating the amount of anodic material remaining in the central anodic coupler and anodic base.
