Irrigation/One zone does not run


Zone one on my Toro TMC-212 does not run. This is the case automatically and manually. The other zones work in either case. What do I do about it to fix it?

If a zone doesn't work it is typically an electrical issue.  I would check the station terminal (see if it is putting out the proper voltage) check the zone wire from the timer to the valve.  Check the ohms to make sure there is no open circuit.  Last check the valve solenoid of the valve in question.  The solenoid is typically the most common cause of your issue.

I am able to answer any questions related to lawn irrigation systems and backflow devices. But pumps are not my speciality since they are not common in my area. Most of my product experience is in Hunter, Rainbird and Irritrol components.
