Abstract:
A water scale reduction apparatus to be connected in a plumbing system to reduce scaling downstream thereof comprising:(a) an elongate tubular flow member having a central passage with first and second passage openings directing a water flow therethrough; (b) a first metal surface in said passage having a specified area and formed on the interior of a conduit defining said flow passage; (c) an elongate second metal surface in said passage and spaced from said first metal surface, wherein said second metal surface is formed on the exterior surface of an elongate metal coil positioned within said conduit and between said passage openings; (d) an electrical insulator mounting said second metal surface in said passage free of contact with said first metal surface so that current flow between said first and second metal surfaces is through water in said passage; and (e) wherein one of said metal surfaces has greater affinity than the other so that said one surface collects greater deposits of water scale than the other and said surface has greater surface area than the other surface.
