You can rent a locater. *Just hook it up to the wire that goes to the valve.
Then wave the receiver over the ground to locate the wire.

That sounds like a workable solution. I saw one of those used for
locating the water line coming into the house and the sewer line too.
The units they used had a line they inserted into the pipes and then
followed it. I didn't know there was one that might follow an
existing electrical line. I will check out the local rental center to
see if they have one.

Thanks,
