My boss asked me a question I am not exactly qualified to answer as I have nearly 0 pump experience.
He has a well pump pulling water from a 200' deep well that he uses for irrigation purposes at his home. The pump has a disconnect switch and surge protection at the house panel and also is grounded to a rod; however, the pump has been destroyed now by lightning striking somewhere nearby. He is thinking that the current is coming through the ground and hitting the pump and following the piping down to the water. The pump is in an area with trees nearby but it is over 100' from the home.
The disconnect and surge suppression show no signs that there has been a lightning strike, but he's had to replaced the pump twice in 6 months now.
Does anybody have an idea how to stop the lightning from destroying the pump? A friend suggested placing a length of pvc in the pipeline to break the "grounding system" the copper tubing creates by going down so far. Would this work? Any other ideas?
Thanks so much!
