Toro 1.5" valves won't come on
I've got 3 Toro 1.5" valves that won't come on. There are only 3 in the system. The lady cleaned out the valve box because golfers filled it full of dirt. The valves worked previous to that so I thought it would be a loose or bad common/ground wire. The connections checked good and I even ran a new set of wires to check it but the valves only vibrate slightly and you can feel a small amount of water running through the valve but not enough to make them come on. The valves work manually (by using the bleeder or turning the solenoid). I took the solenoid off and the pin does retract when the timer comes on. I allowed the water to flow out of the small holes below the solenoid and it did not seem clogged. The voltage at the timer is 24 volts and 23 volts at the valves. It's confusing to me that all three act the same way. Any suggestions?
