After posting this I called a company back in Ca. Hydroscape, a parts wherehouse that sells all Irrigation products,
they , the manager confirmed that certain anamials are atracted to low voltage that they can sense it or smell it so to speak. He said here in the midwest, that gophers, moles @ groundhogs are also known to be attracted to lowvoltage. So just because my valves are under ground and in boxs does not mean that I'm 100% safe from such damage. It just felt good to know I'm not crazy.
Tom,
