Why is my irrigation valve stuck open?

Debris under the diaphragm, a damaged diaphragm, or a solenoid that will not seat can keep a valve open. Shut water supply, disassemble and clean the valve, replace the diaphragm kit if torn, and flush the mainline. A leaking bleeder screw or manual bleed lever left open will also pass water.
