Question
1" Female Thread, NPT, Jar-Top. I have k-rain irrigation electric valve zones and i am running 4 zones. Thing is when i turn my ball valve on all my sprinklers come up and i cant control it with my control box that i have wired them to. When you breath through them air comes through the other side, how do you turn it so when you blow air it doesn't go through. I have taken the jars off and there all clean and the wiring is perfect.

Answer
Hi Sean

You mean all the zones come on at same time?

They are all open because:

1.- All the selenoids are connected to ONE port, connect one selenoid to only one port at the controller, or
2.- The selenoids are on ON  position. Turn at OFF position, or
3.- The bleed assembly is at faulty, replace it, or
4.- The diaphragm at the valves is defective, replace it.
