To repair a leaking sprinkler valve, first turn off the water and power, then open the box and unscrew the solenoid valve, disassemble the valve and clean all of the components. If cleaning the valve does not solve the leak, replace the solenoid valve. Solenoids sit on top of valves and control a small plunger that turns water on and off. If you are using a manual sprinkler system, these solenoids are the control point for each valve. Shop underground sprinkler valves in the irrigation repair section of Lowes.com.
