Hello everyone, I recently purchased a home with a sprinkler system, builder installed in 2006. I had a couple of minor repairs to do with bad heads and the like. My question is, I have 9 zones wired in the Rainbird ESP Modular controller, but only 8 operate, being there are 9 wired, should I actually have 9? The only area not getting watered is on the other side of my driveway, the entire rest of my yard is covered by the 8 operating zones. I have walked the yard and can only locate 3 valve boxes, two in the front yard, one in back, each have 2 valves in them so there are 6 so far. Zones 1-4 cover the front yard and 5-8 cover the backyard. Now I should have a valve per zone correct? If so, I need to locate either one or two more valve boxes. None of the valve boxes I have opened so far have a pink wire in them, which is zone 9's color at the controller. Thank you!
