"I started from scratch and ran my sprinklers with water and every zone worked perfect.
Every zone started and stopped as they should."
Ran them from where? The valve?
"I disconnected all the remaining wires to to other zones and still all the zones came on again."
The zones still came on even though disconnected? If this is true, sounds like crosswiring.
Hi, I ran my sprinklers as if I was watering the grass from the control timer box. Every zone came on and shut off as they should. I then attempted as I've done for years and attempted to blow out the sprinklers by going to each zone from the controller box. Doesn't matter what zone I attempt to blow out. They all come on at once when I attempt to blow them out with the compressor. I disconnected the other zone wires except zone 1 from the timer and all the zones still come on with the air. By going to the valve box and shuting off the flow control valves to all 6 valves I was able to blow out each zone one at a time.
I have a diagram of the system when installed and every wire is hooked up from when it was installed. No one has ever done any repair work to the system.
Thanks,
Bob
