At the pitless adapter. How would one install and transition into PEX from the pitless which is a threaded female adapter?

I thought I answered this? I guess it didn't go through. Anyway with a 1 1/4" pitless, you will need a 1 1/4" male pip adapter to Pex. You may not be able to do that with one fitting. Just go from 1 1/4" male pipe thread to whatever you can find to attach to Pex.

Thanks for the info
On the brass pitless when I unscrew the temporary galvanized pipe. I can just unscrew it from the outside without any worries of something loosening on the inside of the well, right?
On the brass threads do you typically use pipe goop or teflon tape?
I found this brass SharkBite that is 1 1/4" male adapter to 1 1/4 PEX
Interesting that the INNER DIAMETER of 1.25" PEX is 1.00"

That fitting looks like it would work. And yes you can unscrew the pipe from the pitless without disturbing anything inside the casing. But you need to use a backup wrench to keep from turning the pitless shoe sideways. You should also check the friction loss of that 1" ID pipe to make sure it does not cause any restriction between the well head and the pressure transducer.

The pressure transducer will be located inside the garage so the 1" ID PEX pipe will connect to the transducer inside the garage area. No restrictions.
At the pitless adapter the PEX will run underground about 80 feet to the garage where it will resurface and connect to the transducer.

The charts I looked at show 1" PEX to have from 18 to 23 PSI loss per 100' at 20 GPM. If I remember correctly you are shooting for 26 GPM? I don't even see a chart with more than 20 GPM for 1".

Average pump output is 13GPM. So the 1" inner diameter PEX will suffice.
Pump can put out 23 GPM but that is at full flow open line which is not required/needed for the house.

Just need some info before I dive into this job.
Looking at the below photo. I want to remove all the galvanized pipe up to the pitless adapter. I can do that without any worries of the pitless adapter coming loose in the well, right?

The large brass nut at the pitless (see photo) will be held in place with a wrench and then I plan on just unscrewing the male galvanized pipe that's currently threaded into it. Then it will be replaced with a 1.25" brass SharkBite male adapter. See photo.
On the brass threads do you typically use pipe goop or teflon tape?

Don't hold the brass nut but the fitting the brass nut screws on to. As long as you don't unscrew the brass nut off the fitting the pitless will be held tight to the casing. Teflon tape or pipe dope either will work. I use both with the tape first then dope over the tape. In my opinion Teflon paste is too slick and doesn't let the fitting get tight.

Your pump installer should've gave you the option to use PEX or Wirsbo/Uponor. If he didn't have the products or equipment to do the job, then he should've recommend you to a plumber that knows what he is doing or the plumber needs to ask the pump installer what size pipe to use so he doesn't cause friction loss when running multiple faucets at once for both houses.
I would post some links for you but I don't have enough posts yet. A male adapter would do the job coming out the pitless with a solid 1.25" but I have used SharkBite fittings on brass/copper tank tees on tank removal with no problems as well when the line going to the tank is copper and not brass. I wouldn't recommend 1" for two houses. I usually see 1.5-2" pipe being used for two houses.
You can test friction loss by the way, just ask me how. For the people that have low pressure in their house and they can't figure out why when the plumber is blaming the pump installer for installing to small of a pump. I guess the plumber doesn't realize that the faucets he is testing uses less than 10gpm so there should be no problems unless he didn't do something right on his end.
