Toy, CPVC is just as bad as PVC and is also illegal in a commercial shop, and for a good reason. As I have pointed out before just the water problems it contributes to is enough to avoid it. You would be far better off to use metal lines as plastic is a loser no matter what type you select and there is just no good reason to use it.

I was considering PVC when I plumbed my shop air until I researched it a bit and saw the danger of PVC. My shop is plumbed with 1/2" copper. I sort of did a "U" shape In the ceiling around where I work on my car. I put in drops that I can reach up and plug into about every six feet. This allows me to use several short hoses that aren't near as much in the way as one long one that will reach everywhere. It's a lot neater for me this way.

Schedule 40 PVC is nearly as costly as copper. Not so much the lengths but the fittings and such. May as well just copper it and forget it. The bigger the mains are to the outlets the less pressure you'll lose. For a couple bucks over the cost of 1/2" you can go 3/4. Common service line for water. Why? More tank capacity. Why plumb a small garage? Yes reels are OK. But the best reason to plumb is to get air where it won't go otherwise. In my 30X40 shop I plan to run air line to the main garage door and the pass door. That way I get 30' closer to something in the yard and 40' closer to something in the driveway. Beyond that, no matter. Just something to think on. Go metal and you can't go wrong.
