Diode device and method for repairing sprinkler system with faulty wiring between control box and valve

摘要

The present invention is directed to methods of repairing a sprinkler system with faulty wiring between the controller and a one or more of the valves, and associated repaired systems. The method includes identifying the faulty electrically conductive line having electrical discontinuity between the controller and a corresponding first valve, and identifying a non-faulty electrically conductive line having electrical continuity between a controller and corresponding second valve. Control over the first valve is achieved by sharing the non-faulty electrically conductive line between the second valve and the first valve. Forked wiring segments are inserted on both the controller end and the valve end of the non-faulty line. Each inserted wire segment includes a diode to permit current to flow in only one direction allowing both valves to be controlled through only a single shared “hot” line.
