6 zones and 2 are not working
I have a 6 zone automatic sprinkler system. I seem to be having a problem with 2 of them not coming on. The zones are on different areas of my lawn, one on the front side, the other on the last zone in the back yard.
I really have no clue on where to even start to look at what the problem may be. Any help would be greatly appreciated.
One other note, I did notice that when I ran a "test" on all the stations, at one point, I heard some "whining" type noise coming from one of the stations areas. Would this have something to do with it?
