Thanks, I keep looking and cannot find the other boxes, one I thought might be it controls front yard. So....I guess I need to find someone to help. Thanks again.
Ok, I am a new female homeowner with 2 puddles, started small getting bigger. I have already replaced and replumbed the sump pump in the backyard so I'm feeling handy. I can only find 2 green valve boxes and the one closest to back has one SRV valve in it. I have 12-13 different zones. Tried twice to get repaired, man never showed up. I want to try to repair myself if possible because as luck would have it, now my sewer pipe is leaking from the slab. Yes, I had everything inspected before buying...
