The basic components of a lawn sprinkler system include the irrigation controller, pipes, sprinklers, and the irrigation or sprinkler system valves. Irrigation valves control the flow of water to the sprinkler system. Each valve is responsible for one area, or zone, of the lawn sprinkler system.
1. Lawn sprinkler valves may be above ground, but often the sprinkler valves are placed in a valve box and buried, making it difficult to find lost valves.
The most cost-effective way to find irrigation valves is to estimate the irrigation valve location, and probe the soil gently in that area. This is not recommended unless one is sure that the lawn sprinkler valves are protected by a valve box. Otherwise, probing the soil may result in damage to the solenoid, the valve wires or the sprinkler system pipes.
2. In automatic sprinkler systems, a third way to find lost valves is to follow the wires from the controller. The wires run alongside the PVC pipe to the irrigation valve location. Dig small holes every ten feet to trace the wire. Be careful not to cut the wire. It is helpful to note that buried irrigation valve wires rarely run under driveways. Sometimes this location method will find the buried lawn sprinkler valves. Again, one can dig up a large portion of the lawn while trying to locate irrigation valves.
3. Turn on the zone in question, and note which sprinklers are the first to pressurize. These are the sprinklers closest to the irrigation system valve.
