Hi, I inherited my sprinkler system two years ago when we bought our house. I used the system once last year and it worked fine. This year I noticed water gushing around one sprinkler. Research told me it was not a broken sprinkler, but something more. Today I ran the system fully through all 6 zones. When zone 3 came on, zone 2 would not shut off. It stayed on to the end while all the zones finished. I have a very old Hydro-Rain box controlling the system. The system would not turn off when I used the off switch. I have three valves in the control box in ground. Not sure which one controls which zones. Took the middle one apart and cleaned it. Tightened screws very tightly. SOS. help....What the hell is going on?
Thanks,
Dave
