Replacing Pressure Tank - Plumbing advice needed

[Asker123]

I am posting the pictures of the old and the new tank in the next post. The old pressure tank seems to have a horizontal female thread so in order to connect to the male thread of the Tee, the previous owner has used a nipple and a coupling.
My new pressure tank has a vertical 1" male thread so how do I go about to connect to the male thread of the Tee ?
Should I add a coupling and a nipple and then a 90 Deg elbow to make it Horizontal and then another nipple and coupling to connect to the Tee?
Is it advisable to connect such pressure tank connections using a Pex pipe after converting the threaded end of Tee and the Tank to Pex using some converter fittings?.
The work will be accomplished by me and my friends who are good in DIY but wanted to check out here what is my best options.
Oh yes, another point to keep in mind that the old tank has a slight movement whenever the pressure switch cuts off so the connection should be able to withstand that.
Reason for change - Pressure tank and old and every year loses pressure and recently it started leaking from the connections ( probably due to movement as I described above)
Thanks in advance.

good in DIY but wanted to check out here what is my best options.

I would just tread on a 1" brass elbow and a nipple long enough to get to the tank cross and controls.

The tank was losing air because of a bad bladder. The tank movement at shut off is from water hammer. Both of those things are caused by the pump cycling on and off. Your "best option" would be to add a Cycle Stop Valve to the well line before the tank cross while you are doing all this plumbing. The CSV will solve those problems and many more while delivering strong constant pressure to the house.

Thanks but I don't want to put a CSV at this stage. Just want to connect to existing Tee using fittings

I presume small black flex line goes to the pressure switch. That suggests you are probably using a jet pump with a pressure switch mounted on it.

Is it advisable to connect such pressure tank connections using a Pex pipe after converting the threaded end of Tee and the Tank to Pex using some converter fittings?.

It is preferable to keep the path from where the line to/from the pressure switch connects on the tank tee minimized. The tiny size o that line to the pressure tank does not matter, because it has near-zero flow, and therefore near-zero pressure drop.

You can add more stuff that is not in line with that spot and the pressure tank input.

PEX may not be as flexible as you think. If there are elbows, that can allow some flex, but short straight lengths of PEX are not very flexible.

So best would be that you connect the tank tee to the tank in a straight-forward way. Adapt the lines from the well and to the house by adding whatever.

It is also possible to connect house and well pipe with a tee, and run the third leg of the tee to one end of the tank tee. In other words, the path from well to house does not have to go thru the tank tee. The advantage to that is there is only one line to play with when you replace a pressure tank, but you should get many years out of a pressure tank.

Yes the pressure switch is almost 3 feet higher than the Tee. Not good but seems like they were short on wires so they got the switch to where they could and used a damn 3 feet line to the Tee. Lol

Not a problem. Negligible pressure drop, since there is negligible flow. There is a slightly lower pressure at the switch due to static head. So an idealized 40-60 pressure switch would kick on at 41.3 PSI measured 3 ft lower.
