I am wanting to install a sprinkler system at my house. I have 3/4 PEX coming from water meter into my house. I was wondering the best way to tap into this line. I want to run PVC for the sprinkler system so I will need some sort of 3/4 PEX fitting with a tee for the PVC to run off of. Can anyone provide me with direction on what fittings will work?

3/4" PEX might work for a one bath home. Not for irrigation though.
I would pull something much bigger right off the meter if you're planning on popping the heads up on your irrigation. There is a lot of friction loss with the small lines and PEX is a small size anyway.

A chart for PEX
You can see how much better 1" is over 3/4".

For most residential homes for irrigation 1/2", 3/4", and 1" PVC is the norm. To switch from PEX to PVC, sharkbite is the best way to go but since it will be underground, the coupler must have a silicone wrap around it. You also will need a backflow device before the irrigation system.

Not knowing the size of the yard, type of sprinklers you want to use and GPM your city water can provide, it hard to say if 1" inch would help unless you have very long runs. 1" will reduce the friction as Terry stated. For the most part you run 3/4" everywhere and tee off to the sprinkler head with a 3/4x3/4x1/2" tee. https://www.homedepot.com/p/Charlot...-Thread-Reducing-Tee-PVC024012900HD/203812421
