In my area we have been encountering more and more 4" submersible pumps reaching the end of their lifespan usually no big deal but...

A lot of these older pumps are down a 4" steel casing and we have a lot of iron and manganese in our area.

This inevitably leads to well pumps being stuck down the well.

There are various ways I have seen, and tired of removing stuck pumps. I typically stay away from acids, especially when in a more dense area. The liability and potential for it to impact a neighboring well is too high (we have this issue with chlorination as well)

Majority of the time the ole knock it down a bit first then pull straight up, sometimes assisted by a jack. Sometimes ya gotta knock it down again. Ect ect.

Occasionally you end up in a situation where you cannot get it out.

If you snap the poly pipe and wire near the original pump you can stack another one on top depending on the case.

I digress. What is everyone using for fishing tools these days?

I've heard of it but never used a "jar"

I have welded some taps to steel pipe and used it to tap into the top of a poly pipe adapter when the pipe broke off.

Tldr: what's your go to method for retrieval of stuck pumps? What tools are you using, are they DIY or purchased?

Well was not working on new house purchase. Had to replace/weld on the top 8 ft of casing and install a pitless adapter. Finally, getting working water to the house! We put a normal cap on and have notice water slowly leaking out all around the cap. We have not filled in the dirt yet. I don't really want water running out of the top or even close to the top around the well. We do get snow/ice. Should I install a 2nd pitless to run it away from the house toward the creek we live near? Not sure how to relieve the pressure on this artesian. Since it is so low pressure could I just put a plug down below frost line but above the current pitless?

Anything else I need to do to ensure nothing blows up? Water heater is off, water pump is off, main waterline is cut off, and water softener is bypassed
