That's what my buddy who recommended called it. I have a 50 yr old well, well and casing still looked good so I replaced the submersible pump 10 yrs ago, being a diyr I probably set the pump to low in the well. It's about a 100' well with 8" steel casing. Funny thing I found the pitless adapter wrench in a scrap pile on property. Did everything from the well pump to my new cabin in PEX. Previously the pump was set in plastic electrical conduit pulling the old pump up every coupling broke LoL only thing preventing pump from dropping was the wiring.
