Since irrigation valve electrification in the early 1980s, the system of two electromechanical controllers in the backyard red patio—one for the front yard and one for the back—had served acceptably well. Designed for turf irrigation, their 30 minute maximum cycle time proved inadequate for reasonable drip irrigation. Besides, with no rain cutout and not really enough zones for additional valve circuits, it was time for a change.
As it turns out, the new irrigation controller did not arrive until 2005. What did occur in 2002 along with the new water piping was some Extreme irrigation electrical infrastructure installation: Conduit.
