My house has 300′ of 3/4″ Schedule 40 PVC pipe for a main water line. I’d like to “T” off it and run 60′ out to a new shed. I have 2 questions:
1) Should I match the existing 3/4″ or can I use 1/2″
2) What’s the best way/steps to cut into the main? I can’t figure out how to cut out small section and manipulate the lines such that they will form a solid connection with the “T”.
Any help/suggestions would be appreciated.

I've done alot of this sort of thing with PVC>
Why even consider 1/2" cost is not that much different and volumn capacity will be affected.
To do the joint, dig at least 3 feet either side of where the tee will be, put the tee on the line, mark where the ends will be, cut out a section (sawzall would work well here)dry fit to make sure you have enough flex to bend out enough to slip the ends in the tee, , prime and cement. Make sure you have enough room in the trench to manipilate, cause once the glue goes off, it's done.
Make sure you're ready to keep pressure on the joints for 30 seconds or so, so it doesn't push apart on you.
Good Luck
Instead of flexing the existing line to get it into the ends of the T, I would use a compression coupling to put the line back together.
And I agree with Johnny, no good reason to use 1/2".
You mean the rubber couplings with stainless clamps? Or he could always get a couple of unions.
Suprising, though, how much that stuff flexes.
How deep is the trench?
Something like this is what I had in mind.

Oh, it wouldn't be hard to flex it enough, I just figured the less you have to flex it the smaller the hole you have to dig.
What is the line for? If it's simply for a sink or faucet with a 1/4" supply tube, running 1/2" line 60 feet long should be plenty. If it's for a hose bib, then I would definitely run 3/4" if possible.
