Abstract

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.

Dependent claims

A sprinkler system comprising:

a plurality of sprinker valves;
a controller for controlling the plurality of sprinkler valves;
a first hot electrically conductive line having electrical continuity between the controller and a corresponding first valve, the first hot electrically conductive line comprising a first segment, a second segment, and a third segment, the first segment electrically connecting the controller to the second segment, the second segment electrically connecting the first segment to the third segment, and the third segment electrically connecting the first valve to the second segment;
a second hot electrically conductive line having electrical continuity between the controller and a corresponding second valve, the second hot electrically conductive line comprising a first segment, a second segment, and a third segment, the first segment electrically connecting the controller to the second segment, the second segment electrically connecting the first segment to the third segment, and the third segment electrically connecting the second valve to the second segment;
wherein the second segment of the second hot electrically conductive line is the second segment of the first hot electrically conductive line so that the second segment is shared and includes forks at both a controller end and a valve end;
a plurality of electrical diodes including a pair of first segment diodes and a pair of third segment diodes in which:
a first segment diode is disposed on each first segment between the controller and the fork at the intersection of the second segment with the first segments;
a third segment diode is disposed on each third segment between the corresponding valve and the fork at the intersection of the second segment with the third segments;
and
a common electrically conductive line having electrical continuity between the controller, the first valve, and the second valve.
