I used 160psi 1" poly 30+ years ago, 900' run, no issues. If I recall correctly, you can get ~20 gallons a minute with 1" pipe. More than adequate for my needs.

Polyethylene black pipe for sure. don't know why people are suggesting PVC lol. Use PEX inside the house only.

! 1/2" black poly here, heav.y wall but a bit of flexibility plus rock resistance.
That is also what my down well piping is.

To answer this question you first need to know how many GPM your well is capable of producing. If you can get 50 GPM out of your well then run a 2" line. If your well is only going to give you 3 GPM then do not waste your money on large pipe.
In fact, if you WANT sediment to build up in your line use a large line size that moves a minimal velocity of water.

My well is 500' with the pump set at 400'. I have 1 1/4" poly pipe from the pump to the pitiless adapter. The run from the well head to the barn is 220' using 1" Pex. The well produces 12 GPM and I can easily pump it dry if the water runs long enough.
There is no sense in sizing a pipe to handle a flow larger than the well & pump can deliver.

I run 1 1/4” hdpe from the pitless to the pressure tank/CycleStop valve (reduces to 1” at the tank/valve). 3/4” PEX to a Viega Manabloc. 1/2” PEX runs to fixtures. Well flows about 11gpm. 2 hp pump with about 50’ of head to the shop. No flow or pressure issues.
I’m not a fan of PVC for water lines-bad experience on a prior home.

I would be placing the PEX into a PVC conduit pipe to protect and insulate it. Last time I ran PEX for a water line, it was installed in a conduit pipe for protection and insulation.

The water line comes through the stem wall, just above the footing, and then it enters the home under the slab. It comes into a mechanical room which has a small 3 gallon pressure tank as I use a VFD well pump so I don't need a large pressure tank. I actually don't have room for a large pressure tank so the small 3 gallon pressure tank works well as it attaches to the wall using a bracket.

Typically the underground is polyethylene not pex. Pex is a more modern material
