Running pipe through beams
I have a question. I am going to be plumbing my garage for Air and water in the not to distant future. I am using PVC for the water and copper for air, anyway, I want to place the pipes above the beams so I can cover the ceiling. What's the best way to notch out the beams short of using a sawsall?
Of course the beams are not running parallel to where I am running the new lines. Any thoughts? I can even drill holes for the PVC because it’s flexible, but the copper is not an option. Any help would be appreciated. Thank you.
Jim

The water lines must be inside the insulation or they will freeze. The air lines can freeze also from moisture in the lines.
If you notch a beam it can seriously affect the strength of the beam. The best method is to drill a hole thru the center of the beam.
Most air lines are run along the wall near the top using down-legs with drains where you want air. There are several threads here with good info on how to run your air lines.

you could go with cpvc for air insted of copper. shed 40 1/2" id is good for 600 psi.
then you can just drill 1" dia holes about 2" from the edge for making the run of air and water. you would also have less water/condensation in the air lines. it would save you on buying both materials too.

The CPVC is different stuff, I haven't got all of the info I want to see on that stuff yet. But the information I have found on the web so far seems to say:
DO NOT USE CPVC WITH COMPRESSED GAS!
Here are a few links:
http://www.plumbingsupply.com/cpvc.html#faq
http://www.pep-plastic.com/manufactu...2119910-00.pdf
This one is from a manufacturer that lists:
"NOT FOR USE WITH COMPRESSED AIR OR GASES
Spears Manufacturing Company DOES NOT RECOMMEND the use of thermoplastic piping products for systems to transport or store compressed air or gases"
http://216.239.41.104/search?q=cache...hl=en&ie=UTF-8
http://www.findarticles.com/cf_dls/m.../article.jhtml
Here is another manufacturer that states never use it for compressed gas right on the cover of their manual: http://www.cepex.com/pdfs/CEPEXVLS.pdf
All of this info came up on Google with a search term of- cpvc compressed

Why must every discussion about air lines turn into a discussion about PVC and blowing up? I have read more posts than I know what to do with about this and it’s the same outcome. Copper is not that much more expensive than PVC and is a lot less expensive then iron. If we need cheap as I do, go with copper and be done with it.
PCV = cheap = bad. The stuff explodes under pressure and that's it. No discussion.
Copper = cheaper than iron = not bad. If there is a need for the air to escape, it tears. Still a bit dangerous if you are right next to it when it pops, but still better than shrapnel.
Iron = expensive = great. That’s about it. If you can afford it, go with it, otherwise go with copper.
Now back to the questions at hand. I want to thank everyone for their ideas. I am just looking for ideas with routing so that I can hide everything. I am covering the walls with silver side foam and want to make sure everything can be hidden.
Thanks to everyone for their suggestions.

You will need to find a way to keep the pipes from freezing. Will you insulate between the beams or are you putting your insulation up higher?

Of course we wouldn't have the problem if everybody used the search function and found the existing info on air lines instead of starting a new thread... Not that this thread's topic was covered in any previous thread. This was a legit question.

Well, as I can see cost wise, I will be putting R-13 behind the foam, the foam is more for the wallcovering than insulation. I had considered drywall but I just don't want to have to spackle. Anyway, I will be insulating between beams, and so you know, I will be draining the pipes of water in the winter unless I will be using it over that weekend, then the furnace will be on anyway.

Eric, it never ends, does it? lol
What we need here is to re-address the 'garage and workshop' link on the main index so when someone clicks it to view this forum, it sends them to a page that says, DO NOT USE PLASTIC PIPE FOR COMPRESSED AIR OR YOU MAY DIE.", in big red letters. Then at the bottom, two buttons. One for agree, that brings them here, and one for disagree, that one sends them off to stupid land....

Because every time someone comes on and says PVC is GREAT for air lines! -And we have to go thru the whole educational process again.

Should have been more specific. I was actually more irritated by the post about using PVC than the response. I have to agree with Freight Train to a point about maybe making some form of sticky on this with a really catchy header. Like free booby pics or something that everyone is bound to look at. then once they are sucked in, nail them with the PVC is dangerous!

Similar "scams" have been used in other parts of these forums to get people to look!

How big are the beams? You should not notch beams to much or not at all. The old rule if Iam right is 1/3 out of the center and 1/3 out of the center of the lenght but that was on a floor joist.
PVC is bad I have had it blow.
