Why is my Rainbird sprinkler valve leaking?
Leaking valves can be caused by a damaged gasket. There is also an O-ring on the solenoid that should be checked. Rinse off any debris on the surfaces of the parts. Dislodge debris if it is clogging any of the “ports,” the tiny holes that are found in the diaphragm and the plastic base that the solenoid screws into.
What are the parts of a sprinkler valve?
The main components of sprinkler valves are the diaphram, solenoid, springs, and various gaskets or O-rings. The solenoid, an electric cylinder, is a crucial part of an automatic valve. The solenoid receives electric message from the sprinkler system controller, and in turn controls the movement of the diaphram.

What causes a sprinkler valve to not shut off?
If your irrigation system does not turn off, you need to isolate the problem. This starts by checking the main water line and the controller. If those are working, then you need to locate the valves and check to see whether they are dirty, the diaphragm is torn, or the solenoid is broken.
What causes a sprinkler valve to stay open?
Air Trapped in the Valve: The valves may have air trapped in them. A small bubble of air becomes trapped in the tiny water ports of the valve, this stops the water from flowing through the port. Since the water flowing through the port is what holds the valve diaphragm closed, the valve stays open.
What does the bleed screw do on a sprinkler valve?
To close the valve, turn the solenoid clockwise until the valve closes. This is the method that many prefer because most times when you open the manual bleed screw, it causes water to leak out into the valve box. If the valve is left on for any period of time, it can start filling the valve box with water.
