  • Patent number: 10385551
    Abstract: Devices, apparatus, systems and methods for preventing lightning surges from entering metal plumbing, such as copper plumbing through the outside water hose valves, so as to eliminate pipe leaks caused by lightning strikes. To use the invention, the installer removes existing metal valves, and clamps a durable high temperature resistant non-conductive pressure rubber heater hose to the exposed exterior end of the copper piping. The other end of the hose is clamped to a reducer and a water control valve, such as a spigot. The assembly interrupts electrical surges from lightning from passing into the metal exterior valves on the sides of buildings and houses, which can damage the inside metal plumbing, such as the copper plumbing in the buildings and houses.
