Quick answer: Buried sprinkler valves can often be narrowed down with system layout knowledge, electrical testing and professional wire-tracing equipment before targeted digging begins. Random excavation is usually slower and causes unnecessary landscape damage.
Why valves become difficult to find
Valve boxes can be covered by soil, mulch or turf over time. Older systems may also have incomplete plans or valves installed far from obvious locations.
How wire tracing helps
When usable field wiring is present, a locator can follow the electrical path from the controller toward the valve area. Electrical testing can also help identify which conductor belongs to the missing valve.
What if the wire is damaged?
Broken or shorted wiring can complicate locating, but testing may still narrow the problem and identify where additional investigation is needed.
