Zone 2 of my Orbit 6 Valve system always runs while the other 5 zones are turned on either manually or with the control box. Orbit kept assuring me it was a wiring issue and even went so far as to send me a free new model -#57896. I give them credit for their customer service. I'm almost positive I have it wired correctly and have triple checked the wires to make sure they match up with the colors at the valves. I also have two white wires in the common valve slot and one blue wire in the pump slot.
The 6 valve system comprises of 1,2, and 6 in the west box and 3,4,5 in the east box. There is an anti-siphon valve next to the west box and it is connected to the common wire and the pump wire. I have replaced valves 1,2, and 6 and replaced the solenoids last fall- and have since double checked the diaphragms and cleanliness of these valves and their wires, but have done no rewiring or checks of the east box.
I've disconnected the zone 2 control box wire and zone 2 still turns on. Also when I manually turn on the system at the anti-siphon valve, zone 2 is the only one that runs and the others will too if I loosen the solenoid. I just can't figure out how the wiring could cause this problem - BUT is it possible that lets say zone 5 in the east box has a bad solenoid or diaphragm, that it would cause this problem? Do I need to revamp all those valves as well?
I'm happy to add some pictures if needed and I hope my info was thorough enough.
Sprinklers are quickly becoming the bane of my existence.
Thanks for any help.
