air line from basement to garage - EricU - 03-06-2018
the back wall of our garage is above one of the walls in my shop. I'm thinking about putting a compressor in the shop and running a line up to the garage.
I suppose if I make it so that water can't be trapped, the material I use isn't critical. I'm thinking that copper might be best though. Any thoughts?

Copper is easy. My current shop/garage is done in copper. I think I'll go PEX in my new shop space though.

I ran 3/8" copper to the garage and placed a regulator in the garage. The 3/8" works good for airing up tires, impact wrenches (depending on size) and paint spraying. I run 125 psi to the garage. Never had a water issue but it does drain back and I relieve air pressure on that line with the quick disconnect . This blows the pressure in the line back to clear it . Your cfm need will determine the line size. Roly

I read the thread title and thought -
Why not just take the train?

You should check building codes in your area. There are some plastic pipes that are rated to 180 psi--but don't use the PVC pipe that you can get at Home Depot, it will get brittle as it ages. Use something like this:

Retailers of air compressors should be able to direct you to appropriate piping.
This chart (scroll down to the bottom and click the "compressed air tables" link) shows the maximum pressure for copper pipe.

In our factory we ran copper pipe to handle the welding gas (argon) which is low pressure; but galvanized iron pipe for our compressed air system.
You need to check the local codes.
This company lists piping (in Pennsylvania):

I put my larger compressor into my crawl space up against the garage. I want to plumb from it around the garage with a outlet in the front of my garage for repair work outside requiring pneumatic tools.
I am thinking of using pex, but have to figure out the logistics of getting it out of the crawlspace, how to drain the tanks and lines in the crawl space, how to turn it off and on all without crawling down there each time.

Watch for sales and air hose is cheap.

I've got three 50' 3/8" cheapie $10.00 hoses up in the attic of my shop, using those as air drops that are above my work benches.
Easy and cheap. They've been up there since 2006 now. If one blows, I'll just replace it.

I also used 3/8" plastic air hose to run from the compressor in the garage down into my basement shop. It made sense to me to put the noisy compressor out there rather than down in my shop. Anyway, that was at least 6 or 7 years ago. The line is under pressure constantly; no problems with durability or water yet.

Ridgid 1/2" ID copper and 6% silver brazing would make a permanent and safe line. A 12" drip leg with a ball ***** valve before going up would allow you to drain the line.
