As long as the pump can go down the PVC liner, it can be set at anywhere below the end of the liner. IN the liner won't allow proper flow to cool the pump and your present pump may not be able to be set that deep. If you need a new pump, I'd go that route before having a liner installed, that's because the casing may not be as bad as the driller thinks since he didn't clean the rust buildup off it. And then there is the part about iron causing corrosion of steel casing. Maybe you heard him wrong or are off a bit from what he said so call him and ask about that.

There are a few very solid reasons for steel casing, one is the fact that most rock bore wells (in to rock) aren't straight enough for plastic. Plus it usually takes decades for acidic water in a well to cause the casing problems. Bad electrical connections at the pump pigtail or damaged wiring or splices from the pump up the well can cause problems very soon though. Using the casing as a ground electrode may also.

BTW, we all should want to become as independent as we can and want less intrusion into our lives by the government.

I recall back when I lived in TN up in the mountains that we ended up having to have the same PVC shaft protector put in on our well shaft as every time it rained really hard it stirred up the water in the well and we got nasty looking water coming out. The PVC shaft protector with the hundreds of cuts in the shaft really helped to reduce that.

Let me say that I know nothing about water treatment, but I would have the pump pulled and the well cleaned either with a brush or by surging to clean up and break down the iron. I would then have an old test pump installed to clear the well of the iron that is in suspension, followed by installation of your present pump if it is still good. Your contractor should be willing to take it to the pump shop and have it tested while he is doing the other work. You may find that the surging has helped to increase the well yield, another added benefit.

As for improper pump cooling in a lined well, BS. It will be no worse than setting a pump in an open hole. As a matter of fact, if the slots are at the bottom of the well, the pump will draw water past the motor when it runs, much like a porter shroud in a standing column geothermal well.

I'm glad to see you agree with me about cleaning the well but...

You are saying that when he uses water and his static water level falls the water to the pump is coming up from below the pump... BS

Also, since his pump is at 200', I doubt his casing goes down that deep so his pump wouldn't be in the liner.

Sure it would, run the liner to the bottom of the well and run two slotted pieces in the hole first with a pump setting at 160'.

Wow, your advice for a deteriorating well casing is to drop chlorine pellets into it? Would that not just exacerbate the situation?

I would put in a liner.

A pump only has to move water for the static water level but since it is at 200', I'd guess it was a 3/4hp but we don't know the gpm.

Have you talked to the camera guy about iron causing corrosion?

he said some corrosion on the casing witch is letting iron build up on the casing walls but no holes in the casing

If your water contains iron, the soluable iron is oxidized as the water pressure decreases and comes in contact with air and that causes rust to build up on the casing in the draw down area at the top of the water column.

Lining the well will not stop that or stop the effect of your acid water. If it were me, I'd have the well cleaned (depending on the cost) and get a backwashed mixed bed AN filter and a water softener.

Hey, wait a minute.
