Bury some 1/2" SCH80 pvc, and do this:

Oh boy, now another thread about not being able to use PVC for air...

That's why I said SCH80.

While pvc may hold up I’d avoid using it specially if buried. Conversation I had with a plumber customer/friend of mine about this. Mainly I was inquiring about using large pex for my purpose. His two story’s about pex and pvc helped make my decision easier. He said when he has a buried pvc failure to repair he will only do it if the whole line is being replaced. He’s done with chasing the problem. It’s really tough when it travels under a driveway. He built a pusher to bore under things like driveways but will not replace the line with pvc. He said when pex came out they came to him with some samples to test and get his feedback. He said they tortured it by blocking the ends off filling with water and freezing it several times and abusing it. They put in very hot conditions. They pulled it between two vehicles stretching it out and a little heat and returned to size. They finally filled it with powder and blew it up.

I’ll stick with the pex for air and water.

So that the shards are heavier. good plan.

Duh, good point. But rusting out in 5 years isn’t a strong plan either.

run pex in the galvanized?

run pex in the galvanized?

Conduit would be easier at that point.

Direct bury 3/4" pex 18"+ in the ground. Easiest (that doesn't look hick as fuck) and cheapest.

Gutter drain tile works great and cheap

Or conduit. It's kind of made for being buried and having other shit fished through it.

I need to check but I think I've got two runs of 12/2, one of 6/2 and one of 3/4 pex all in one 3" or 2-1/2" conduit. Fishing the 12/2s was a bitch but other than that it works great.

i would put a quick disconnect under the roof overhang at each corner and run a hose between them, disco if i need to bring something tall through the gate

why put it up there, if it has a disconnect, just lay on on the ground like a normal person

Digging this up.
What was the solution? I have been running airlines in my shop these past few evenings and was considering running a T-line to the front of my building along the bottom of the outside wall vs running the system further through the building through multiple ICF walls (vs just one more time, and also giving me an outside airline connection at both sides of my shop. The run will be about 80 feet total outside though. I've set the system up to have a low point at the tank, and a few drip points as well for various systems with some valves that I can shut off. The main system is soft copper tubing that I used JIC 37 degree flares on. I was thinking for the long run, to use the conduit like mentioned and slide Pex inside of that to help protect it from UV.

So far my solution has been to ignore the problem and hope it goes away. Just use the co2 tank when I need air in the carport.

I do need to do something sooner than later. Want to re-grade and gravel in front of the shop, airline would need to be done before that
