-Start poking the lawn for valve boxes with a stick. Carefully.

-Or, you can rent a wire tracer. They are difficult to use if you've never used one before.

-You can also call an irrigation expert, and they'll do it all for you.



Try to find where the PVB (pressure vacuum breaker) is on the side of the house and the boxes may be located near that. Although, if the system is old, it may not have a PVB. Over time, the valve boxes will get covered be dirt/grass, covered by a bed of mulch for plants, or even the valves directly buried. (I HOPE NOT :wacko: )
I'm no expert..........YET! :D I just like to suggest things and learn... :thumbsup: See what the pro's have to say first.

There are no wires in a Toro hydraulic system, so tracing is out, and there isn't enough metal in one of those valves for a detector to notice.

Look over the old threads on "Freetime Four" controllers.

By the way, it is entirely possible that an old Toro hydraulic controller could be repaired at the factory.
