Sprinkler Valves
I have had two of six zones out for over a year and couldn't find the valves. I had a contractor out for some maintenence and he couldn't find the valves either. Today I rented a tone generator for $15.00 for half a day, found the two zones. One in 15 minutes, the second an hour and a half (and about six dry holes) later. Thanks - the tone generator solution worked great.
