Start at that sprinkler and try to find the valve nearby. The cheapest and easiest way to find buried irrigation valves is often to probe the soil with a thin rod, such as a long screwdriver. Often you can estimate the rough location of the irrigation valve, then find a buried valve box by probing the ground.

Make sure the sprinkler valve is closed, unless it’s the valve farthest from the main water source. You’ll want to leave this valve open and remove the sprinkler nozzle to allow air to escape when you turn on the water.
Will a metal detector find sprinkler valves?
Metal detectors can find sprinklers heads and valves without a problem because they have some parts that are made out of metal. But if these metal parts are too small, the detector can’t find them. Sprinkler heads have springs to move the riser; valves have screws, springs, and solenoids.

Are sprinkler valves normally closed?
For electronic solenoid valves – the most common type used in sprinkler systems these days – the nature of the valve means they’re ‘normally closed’.
What happens when a sprinkler solenoid goes bad?
What happens if a sprinkler solenoid goes bad? A sprinkler works because the solenoid changes the water pressure inside the sprinkler chamber and lifts the plunger that opens the sprinkler valve. If your solenoid is bad, the water pressure in the sprinkler chamber will not be changed and the valve will fail to open.
Where is my sprinkler solenoid located?
Sometimes the valves are located above ground, usually near where the source pipe emerges from the house to split into various irrigation zones. In this case, it’s usually quite easy to find the valves. Often the valves are located inside one or more in-ground valve boxes.
