Abstract: A sprinkler valve wiring apparatus and method are provided. An irrigation system has a plurality of valves designed to be electrically activated by a control unit. Valve wires extend from the valves to a junction unit. Control unit wires extend from the control unit to the junction unit, and are electrically coupled to the valve wires within the junction unit. The control unit wires include a common wire and a plurality of hot wires. Each hot wire is coupled to a corresponding valve, while the common wire is coupled to all of the valves by the junction unit. The junction unit utilizes resilient blocking members with frangible portions that block unused wire receptacles and can be removed to provide watertight access to the remaining wire receptacles. The junction unit is fixed in place via an anchoring mechanism such as a pipe clip or stake.
