orbit anti-siphon valve on/off lever controls two different pipes!

Hello,
I have just installed two typical orbit anti-siphon valve for my zone 3 and 4, everything was installed correctly, but I just noticed something really weird that I can't explain. So for my zone 3, everything works fine, if on/off level is on, the irrigation starts working regardless of electrical. If it is set to off, only the electric signal controls it to be on or off. Ok, now the problem is with my zone 4, when I set to on, the water flows out of a single pipe (an open pipe somewhere in the garden that I didn't notice before), but if I set the lever to off, everything works normally, the irrigation is controlled by electrical to turn on or off, no pipe water.
My question is: isn't the on/off lever just a manual thing for the solenoid? How come it can seemingly control two route of pipes?
This really bothers me since I don't understand. If anyone can explain, please email me at wepleo@gmail.com

Thank you so much

It sounds like the valve you replaced and manually turning on for a open pipe is not actually zone 4. Since you don't see this run from the controller then more then likely this was a spare zone or abandoned zone in the past. Perhaps a failed wire in the field and someone else couldn't figure it out / abandoned it . Out of the valves you replaced, are there more valves in this area? Did you turn on the solenoid to other valves throughout the system? Be careful with turning the solenoid on orbits, they have small threads and a high threshold point to manually activate the valve. It's easy to accidently pop the solenoid.

Thank you

Hi,
Thank you for the reply. You are exactly right! The valve I replaced was an abandon one. Now everything makes sense. Thank you again!
