I successfully repaired my irrigation system today with the outstanding assistance of this site's members but am very confused about the sprinkler system's plumbing.
The system has four zones.
1st mystery:
There are actually five solenoids controlling the four zones.
Zones 1 and 2 each have a valve and solenoid.
Zone 3 has two valves each with a solenoid.
Zone 4 has one valve and solenoid.
Zone 3 appears to be hooked up in parallel to run the two solenoids simultaneously although the wires are different.
I am mystified about this and wonder if anyone else has seen such a set up?
2nd mystery:
There is a valve 'downstream' from Zone 3 that has a solenoid that is not connected to anything. I pulled the solenoid out and ran the system. Water squirts out.
The two attached images show my system. The first is an establishing image showing all of the valves. Image two shows Zone 3 valves (right side) and the mystery valve (left side) with its unconnected solenoid. Any ideas about the mystery valve?
