Plumbing my garage for compressed air...

We have had copper line in our garage for almost 20 years now, not one problem with it. Literally thousands of cars have been painted using this compressor.

For our two car garage we just ran the pipe around the back to the middle of the back wall. Then we run a rubber hose off of it. The yellow goodyear hose works very nicely for the price BTW, very flexible.
