It especially important that the pump wire is taped back to the poly pipe at correct intervals with pump tape. I've pulled pumps out of the case over 15yrs set with that tape and never seen it fail. It's a particular tape used/sold in the pump business...not duct tape or plastic electric tape.
When you pull poly out of a well, be mindful it's not rubbing on the case anywhere. Any nick in the wiring that exposes the wire underwater will eventually take out your pump. What most people don't understand is that pressure tanks are sized so that your pump runs for at LEAST a minute before shutting off. All the heat is generated on startup and then they need water flowing around them to cool down. The minute plus allows for that....so size your pressure tank accordingly.
And another myth is that you can put a submersible pump for a home/homestead in a 10"-12" cased well and not have to worry about cooling. Wrong! You'll need a cooling sleeve connected around the pump because there's not enough directed flow in a big body of water like that. The pump can actually overheat. That's why most residential/homestead well cases are sized 6"-8".....to generate a good flow around the pump as it draws. The well case itself become the cooling sleeve.
Submersible pumps can run continuously for almost forever....it's the continual cycling that kills them. I put a large pump in once and had it fill a lake, wide open....after that it served a big homestead.....no sweat on filling the lake.
And then there's the whole technology of 'demand' pump systems....they spool up for the amount of flow needed only, using pressure transducers and advanced electronics. Lots of advantages there...smaller pressure tanks, longer pump life, but expensive hardware. Grundfos has/had a line of computer pumps since the 90's. I installed their first generation. Now many installers use conventional pumps that work though a very expensive 'demand' controller....that has a fan and needs air space around it in whatever location the electronics are installed.....pump house, basement etc.

Thank you for your excellent comment .
I really don't have much knowledge about the pump but some systems like how to install pressure tanks, pressure switches, electrical matters and how the system works etc.
I have a 230ft deep well and 120ft drop poly pipe replaced from galvanized pipe in 2016 with a 2hp 20gal Sta-Rite pump installed in Jan, 2006 by local well contractor
The reason to replace the poly pipe is my well water has iron that cause of rust to galvanized pipe rapidly(I have replaced two times in 15 years)
Also, I installed two of 120 gal pressure tanks 10 years ago with a 40-60 psi setup and a filter tank next to the pressure tank by myself.
The reason I installed the filter tank was because when the drop pipe was a galvanized pipe which had produced so much rust debris from the pipe it caused plugging my mini irrigation system and bad water quality.
After replacing the poly pipe, there were no more debris problems and water quality improved a lot better than before.
The main water line runs about 350 ft from the well and 15 ft lower elevation.
Also, installed DEFINITE PURPOSE CONTACTO for main pump switch.
The well system never had any problem ever since being replaced by the poly pipe..
Recently, there was no water in the house. I thought the well pump failed because of age but it wasn't.
The cause was the main pvc water pipe was broken and repaired by myself easily.
But I was very concerned about suddenly no water in the house, so I bought a reconditioned well pump for temporary repair from a local guy who rebuilt the old pump and the reason to make this pump pulling tool in case the pump failed then I can install it by myself in emergency circumstances.
Finanly, I have a question for you as a professional.
I got some information about the Stop cycle valve. It sounds good to me for the constant pressure water with a small pressure tank and they said it saves pump life.
I have researched more details about it. Yes, it will work well for sudden circumstances but not all. Specifically in my needs.
What do you have in mind?
Thank you again
