Locating a Buried Irrigation Valve with a Wire Locator

Finding a Hidden Valve After a Main Line Break

After repairing a broken main PVC pipe near the backflow valve, dirt entered the line causing one valve to stick partially open. The homeowner fixed one valve but cannot locate the second. Most valves are in a well with a 6″ pipe riser, but the problematic valve is missing.

Professional Method

Use a wire/valve locator: disconnect the wire from the controller leading to the target valve, connect the locator’s lead to that wire, and trace the wire with the wand. Signal strength increases over the solenoid, pinpointing the valve. Local irrigation suppliers often rent locators.
