Lightening Arrestor


Our Old farmhouse that we are re-doing, the well pump was replaced in 2006. It recently stopped working. Well company came and did some electrical checks and said the well pump had a dead Short. Most likely caused by lightening.

When we bought our house it had been vacant and wireing copper had been stolen from it. So we are slowly getting things wired and up to code.

Up until today there was no ground from the circuit box to a ground rod. I drove a 10 ft 5/8" ground rod and connected it to the circuit box with solid bare #6 copper.

Will this help with lightening strikes to the well etc. Is there such a thing as a lightening arrestor for wells?

Any suggestions. It is to dang expensive to replace the pump every few years.

Thanks for any help!

Lightening Arrestor


Most small horespower submersible pumps today have lightning arrestors built in. There are optional ligntning arrestors sold for well pumps. However understand direct lightning hits can't be saved by anything.

Motors are hardy, electronics is not.

With a lightning strike I'd think the motor would have failed to an 'open' state instead of failing by shorting but lightning does strange things.
