Lightning hit a tree, went into a septic tank near the trunk, and then presumably traveled up the septic drain pipe (or contents of the pipe?) into the house damaging some plugged in appliances. There was no evidence of a strike on the house itself. What kind of more basic protection could have been in place, aside from the obvious surge protection in various electrical feeder points and sockets within the house? Not knowing the construction of the pipe, I'm assuming that at some point (or possibly many) there should be either be ground stakes from conductive material in the pipes or in touch with the contents of the pipes. Anybody out there have some thoughts or experience in remediating factors in this very strange occurrence?
