Manual Timer not turning water on
We have an older model Toro sprinkler system that was here when we moved into our present home, 8 years ago.
The device has a manual timer that seems to advance normally; but it never kicks off the water at the set time.
The system works when run manually. (there are 4 zones).
Any thoughts to what to look for that should be happening but is not?
Thank you,
Steve
