Is copper the new gold

at worst poke an eye out.

Isn't that bad enough??!!

As stated above, I've seen the aftermath of PVC shredding drywall and a few other things. I really would not want to see what it would do to flesh.

And the point of what if something falls on the pipe is a very valid one. The pipe may not fail from use itself, but if anything hits it that may cause the problem.

Another hazard I have seen - up close - are the plastic bowls on airline water filters. We had one on an airboy used for dispensing motor oil.

It was a slow day, and I was cleaning the place up a bit. I wiped down the airboy, as it was pretty grimy. I was using brake parts cleaner on a rag.

I bent over and sprayed the water trap, and as I was preparing to wipe it down, the plastic (polycarbonate, so the sticker said) bowl crystallized right before my eyes and then shattered.

I did have to dig a couple of shards out of my forehead, but my glasses kept it out of my eyes.

I have since used some filters that have a perforated metal shield around the plastic bowl, and thought it a good idea, but I noticed the other day that the one on my compressor has some faint cracking in the clear bowl adjacent to the round holes in the shield. It must be due to UV exposure, I guess.

Well, considering you should always be wearing your safety glasses in the shop anyways....

And with the drywall, I am guessing the PVC was attached to the drywall.

I really doubt you need more then 6 inches underground to make PVC safe. As long as it is ran in a no heavy weight traffic area.

Is there anyway we could do a setup pvc explosion? Call Mythbusters! We need some ballistics gelatin at certain incriments from the explosion.

What about a schedule 80 pipe? Schedule 120?

The only three real choices are copper, black iron, or aluminum (Garage-Pak).

Galvanized. No rust with that. And PVC will turn into shrapnel if it burst. Razor sharp. Forget the PVC and spend a few dollars more up front and it will last a lifetime.

The oils from the compressor, especially synthetics affect polycarbonate.

Most have a warning sticker to that effect on them.

Actually, you'd be surprised at how much zinc flakes you get going that route...

Yea, take a screwdriver and scrape the pipe. You'll get a bunch of flakes.

I have decided to use 3/4 inch copper from the shed to under the house and then again in the garage.. I will be using black black pipe under the house were it will be a a straight shot to join the copper...I can get the black iron pipe for free .. In the garage I will use 3/4 till the filter and reg. and will size it down to 1/2 inch for the drops.. Hope it works

Copper is not designed for air use the joints can't take the pulsing from the pump plus the LABOR to make connections is time consuming.....Iron pipe is an 100 year old idea but the pipe rusts and thats a big problem......YES copper and iron are way up in price ....... This is not a sales pitch but check out our site bluepipeguys.com this is aircraft 6061 T6 aluminum that is push together and can be taken apart used over again in your new garage instead of leaving the pipe for the new garage owner.

Sorry blue pipe guys, but if this isn't a sales pitch, I don't know what is. It might be a good product, but BS is BS.

Considering that the copper handbooks all state that copper IS designed for compressed air - I'd definitely say that you are just attempting to sell your product. You may have a good product - but attempting to sell it through misinformation just makes you look bad.
