My husband and I are trying to replace our submersible well pump. I was able to see a conversation thread on here from 10+ years ago where somebody had the same type of pitless adapter we have. In that thread it was referred to as a "drill-thru pitless adapter". We cannot get this thing pulled even after reading through all the comments. I attached a photo to show you what it is we have. Any advice for pulling that adapter will be greatly appreciated. Thank you!
