Watch as I find a sprinkler valve using an underground wire finder.

I bought this house with no knowledge of where anything was with the irrigation, and have been chasing down leaks, valve boxes, sprinkler heads, etc.

This is an effective way to find the approximate location of a valve box to help narrow down where you should prod your lawn.

A couple details with this method:

1) You need to verify your wiring is actually good and activates the valve. If the wire has been split or corroded and separated, this method will not work. Verify a working valve at your controller using a multimeter, or simply turning the zone on to confirm water starts flowing at your meter.
2) You've unhooked the power supply.
