While replacing some sprinklers for a friend he mentioned a zone that was not working. I went to the distribution box and attempted to manually turn the solenoid but it snapped off. Toro system put in with the house in the 80's. I can source the diaphragm and the solenoid but do not want to damage the bonnet trying to remove the remnants of the old solenoid:
Looking for ideas on what to do? If I can't source a bonnet then the next step is to get the dremel out and try to remove the remnants of the old solenoid....
