How Sprinkler Valve Locating Works When the Box Is Buried

Sprinkler valve boxes can disappear beneath grass, mulch and landscape changes. When there is no reliable system map, locating equipment can help find them without digging up large areas of the yard.

Follow the irrigation wiring

Most electric irrigation valves are connected to the controller by low-voltage field wire. A locator can apply a signal to that wire and help trace its route.

Valve activation can provide another clue

Depending on the system and condition of the wiring, specialized locating methods may help narrow down the valve position.

Why valve boxes become difficult to find

Turf grows over lids, beds are expanded, mulch accumulates and previous repairs may leave boxes below grade.

Locate before excavating

Once the probable location is narrowed down, the technician can uncover a much smaller area and inspect the valve and wiring.
