Hi! This is my first post to your forum.

I am remodeling my masterbath and will be relocating all the fixtures. I plan to use Sharkbite PEX products (either crimping or clamping) as they seem pretty straight forward.

I'm a little confused though on the specific fittings I am supposed to install between the distribution line and the actual fixtures (e.g., a sink). For example, on one sample illustration they installed a Regulator between the 3/4" distribution pipe and the 1/2" branch lines. What is that for? Is it necessary? I'm also unsure of the combination of fittings I need to go from the 1/2" PEX to something that I can actually attach to the faucet.

My layout is very straightforward. The distribution line comes in from one side of the room and all 5 fixtures are in a straight line down the same wall. Can I just run one 3/4" PEX pipe all the way down the wall and just insert a 3/4 x 3/4 x 1/2 reducing T at each fixture to carry the water to the fixture? Can it be that simple?

Any help you can give me would be much appreciated.
