Why not to use PVC for the shop

You are right about the GaragePak stuff on PowerBlock. I would absolutely not use PVC. Some of the guys ran PVC in our last shop. Knowledgeable, detail oriented, guys. Worked fine for a few years but then started leaking in places and the sagging between supports really worried me. If nothing more than providing somewhere for moisture to condense and sit in the lines. Unless you are going to put a lot of angle on all the lines to control moisture and are prepared to replace it within 5 years go ahead and do it right.
My 2 cents.
Good Luck!

In a friend's shop schedule 80 and 160 pvc worked fine for quite a few years before it started breaking. He replaced it with steel

Does schedule 80, and 40 for that matter deteriorate when carrying water or air? :skep: I have had an issue where a numbskull used the old Silvoline version for a stand pipe in a well. There, after about 7-8 years it starting cracking length wise. I had to pull it out when it was about 10 deg F outside :eek:
 
Has anyone tried nylon air brake lines for shop air line routing?

I see it is available in many diameters including 1/2" 5?8" and 3?4" and pushlock fittings on one site I looked at available up to 1/2",perhaps even bigger?

800 psi burst on the 3/4" line eg:

A buddy of mine is an avid believer that any metal air line attracts moisture-nylon should not have this effect and should not have much pressure drop along it's length.

Makes sense to me that would work.

Any line will get moisture in it cause it originates from outside air before the pump.
With sagging lines one can't drain accumulated water either,it stays in the low spots and only moves when you move the air in the line with using a blowgun or such
 
x2 on that my hoses for framing get water in them all the time. the only diff the metal lines would make is they transfer heat faster and when the air cools off from being compressed it condenses any moisture in it.

Good point.
 
Hey L98TPI I spent a lot of time n Lynchburg. The city of seven hills. Went to The Ground Round a lot back in the day, chili cheese burger n a bowl all the way! Such fantastic cholesterol! LOL Back on the subject, what about using that flexible lp gas line that they used to run the gas to my stove. It looked easy n no worry about ells etc?
 
Isn't that line rated for low pressure? I've never checked that line, but natural gas and propane both are low pressure. Pressure is low enough that I've actually witnessed a professional swapping fittings without shutting down the incoming gas line.

Sorry, I wasn't clear which line I was referring to. I was commenting on the flexible propane gas line orrum was asking about.

I few years back the Ground Round closed, a year or so later Texas Steakhouse opened in the same location, still open IIRC but I have not been there in years. We have so dang many restaurants around here these days.

I have been told that new flexible gas pipe is actually capable of with standing full LP tank pressure as a fail safe.

Also when PVC heats up it has to be down graded in psi rating. When gets to around 140-150 deg F it has to be down rated to 1/2 its psi rating.
 
I used white pvc pipe in my shop for 12 years with zero problems. Didn't matter if it was -30 or the hottest of days. I painted cars and figured why not use pvc and not have to worry about rust in my lines. I have a 2 stage Davilbiss 6.5 hp compressor hooked up with about 125psi in that pvc line. My dad is using the compressor right now, but when it comes back home, I'll use pvc again. Just telling you guys what my experience was.
 
Same here I plumbed my shop with 3/4 inch Schedule 80 pvc(white pipe)about 9yrs ago.Have not had a problem.I did run it up high and drop it down.I was concerned about stuff getting banged into it. I have a 36'x64' shop,so probable 200ft of pipe.It makes a loop around the building,with 10 drop downs,and 4 drains.I think it cost about $100(at menards) to do the whole shop.I have a Quincy 80 gal with 175psi(regulated to 125psi).Very happy with it.
 
Don't want to jinx myself but it's probably been over 12 years since I did mine in 1/2 pvc overhead with galvanized & drains at all the drops where they are anchored to the wall and I've had no trouble. I do shut off the main valve at the tank when I'm not using it.

jmac, Tell us about that Camaro... I'm droolin' here.
 
72 RS/SS supposed to be a red 350/4spd.Now its a 396/th400.I've had it since 1992(i think).I guy one town over had it when I was in high school.It was black with the stripes back then then.I bought it for $1500 with a bad tranny in it.I ran it around for 4 or 5yrs just like I got it(different tranny)Then tore it apart,and gave it the full redo.The interior was the hardiest part.I keep thinking about putting the 4spd back in,but I just hate to mess with it.
Its the same age as me.
That first pick was from a car cruise last summer.The red 87 beside it is mine too,the wife claims it,cause I bought for here birthday(she thinks)The other 2 pics are older.
