I'd like to cut into an existing hot water (copper) line to add a Tee and run a new hot water line to somewhere else in the house.

Do I need a regular Tee or a Slip Tee? I'll be using Sharkbite connectors but it sounds like a Slip Tee is made mostly for repairs so I'm a little confused.

I've already purchased a regular Tee (Sharkbite) but I'm not sure how to measure the section of copper to cut and then how to stick the Tee between the cut ends. It sounds like a Slip Tee solves these problems?

Using a slip tee or reg tee depends on how much movement you have once you cut the pipe. In either case you will need to make 2 cuts to where you want to add your tee. The second cut will be made to remove enough pipe so that once your tee is set, you do not see any pipe when you look into the center leg of the tee. I'm not a big fan of sharkbite, if it's not in a garage or somewhere that it can be inspected periodically then I would consider soldering copper. The sharkbite slip tee will just be slipped all the way onto one end of the pipe and then there is a little tool you will need to back it the other way onto the mating pipe. If you have an old piece of pipe for trial and error that will help you determine how much gap you will need to cut out.
