In the Garage

[sealeveloc]

Ok guy's, Ive got the roof on and concrete poured a few weeks ago. I am roughing in my electric, plumbing and air now. Ive got a question about running my air lines. Metal or plastic? I have 3/4" SCH40 roughed in now, but scared it could burst over time. The pipe is rated to 480psi @ 73 deg. Should I pull it out and run black threaded pipe? Has anyone had issues with using PVC? Ive got two hook ups on the work bench, one over head between the bays, and outside I have a hose bib, 20Amp outlet, and a air chuck. Its about 100' of pipe, but I have access to a power threader. And nows the time to do it, so lets hear some opinions.

I will be using the white plastic pvc you discribe when I plumb my garage for air. Just make sure it is anchored well at the air outlet quickcouplers. And use the proper cleaner primer and glue... yes all 3. Should be good for 125-130 psi with no problem. Buddy has had this stuff in his mechanics shop for 4+ years with no issues I know of.

If you're planning on owning the garage for a while, I would do it right the first time and go with black threaded pipe. You may never have an issue but, when you do, you'll probably wish you would have done it that way originally.

I agree with above....do the black threaded pipe now and not worry about it....ever.

I just pulled over 150`of pvc out of a 3 bay garage and piped in black pipe due to multiple failures. The guy thinks it was 4 yrs old and i don`t know if it was prepped right. Bite the labor bullet and go black pipe just my 2 pence

Dispite my earlier post and continued plan to use pvc in my own garage, I do have to agree that steel pipe is time tested and much more damage resistant. My dad has had steel run thru his garage for 25-30 years with no issues from the piping. Quickcouplers leak and need replaced but the pipe is as good as the day installed. He used galvanized due to semi-exposed to weather issues. (Pole building not totally inclosed)

Thanks for the in site guys. I haven't gone cheap on this garage yet, so why start now, right? Lol

It's in the wall so if it exploded there shouldn't be any casualties, but finding a leak would be near impossible.

I've had black pipe in my garage for over 20 years. The one suggestion I would make is use a good commercial desiccant air dryer at the source to keep the rust at bay. Black pipe is susceptible to rust and corrosion build up.

Air dryer? I was planning a water separator, possibly two?( 2nd about 35 ft. down the line)

Eastwood has a line of dryers. Desiccant actually removes moisture not just separates it like the water separators do. In the beginning I used the so called water separators and still got moisture and rust. None since going to a dryer.
