My well is a shallow well 1000 feet from the house. The well guys tell me that there must be a splice in the underground cable that has corroded as they cannot get 220v to the well. The current cable is a high quality 4 wire underground cable that is deeply buried but not in conduit. They say it is unlikely that anything happened to the cable itself and that because of the distance that it is very likely the cable was spliced and that the splice is the problem. They say that they cannot find the splice and that the only solution is to bury a new cable. The well guys are honest but TBNers are a clever lot so I figure I would ask: Anybody know of a way to figure out where the splice/fault might be so I do not need to get the excavator to bury a new cable?
