DIY: Pitless adapter to SCH40 [View all]

If you don't know what the title means, you probably can't help me. Sorry for the technical jargon.

So there is the 1: brass female threaded adapter outlet. Then there is a SCH40 1" pipe.

PVC has not worked too well. I think they make them too thin and cheap today.

So I need a brass 1" male to male threaded coupling. Fine. If I can find one. I get to use compound and/or tape. But how to I tighten that into the adapter without damaging the threads?

Then there is the transition to SCH40. It would be a straight female threaded to slip-on. That's better than what's on there.

But I also see brass female adapter to well hose. Great points for flexibility on that, would be really good. But how to connect hose to SCH40?

Would a regular plumber do this install, or would i need a well driller? It's my backup plan but being realistic I 'm not finding how to DIY

Thanks TIA for any quick help you can give!
