I don't know for sure where the previous breaks were, but this one was about 10 feet above the one cable guard I could see. I plan to have the new pump guy come take a look at my system when he is in the area, and see if he has any suggestions. I think I need to at least add additional cable guards, maybe one every ten feet for the bottom fifty feet. (BTW: The one cable guard I saw below the break was not round like I see in most pictures, but was square.) It does seem strange to me that the original pump worked for some twenty years, but the wires on this one have failed five times in just three years. There seems to be a fair amount of disagreement on torque arrestors, especially in situations like mine, where the casing ends when the well hits rock.
And, as an old engineer, it still surprises me that there is so much disagreement on these issues after so many years. I would have thought that people would have done controlled experiments using video cameras under various conditions to develop hard data on the best practices for various types of installations. Instead, it seems like as much an art as a science.
