I was just wondering what would be the best way to plumb the garage for an air hose in each "bay".  We've got a 3 car garage with a work room off to one side.  I was going to put the compressor up in the attic space and run hoses or PVC pipe to each bay, and then have a couple of the yellow coil hoses in between.  Just wondering what the burst rating of PVC is.  Would it be able to handle the pressure.  I usually run the compressor at about 100psi.  Or should I use metal pipe instead?  Any help would be appreciated.

Under no circumstances should you use PVC for compressed air, go with metal piping.  The chance of PVC blowing is too great to make it an option.  Run metal pipe along the walls making sure it has a slope to it, putting a drain at the low end that ideally you should open regularly.  Space quick couplers every five feet or so.  It may seem extreme, but it sure is nice to be able to plug into the line anywhere you choose rather than running long lines from one of just three couplers you may have put in.

I work for a plumbining company and checked with them about it and they said you have to run metal pipe.  Ideally you should do what Jphostr said and put in the couplers.  It's good thinking for the future.  If you've got any questions I've got a code book and a design book here.

I've heard that you should only use the black metal pipe not the galvanized pipe.. I have no idea why but that's what i was told... also you should have a flexible hose between the compressor and the metal pipe to cut down on vibrations. I'm not sure I would want an air compressor in an attic either...

if you do put the compressor in an isolated location, be sure it has a source of clean air and the area is vented to dissipate the heat generated by the compressor. it will be safer and the compressor will last longer

Thanks for the helps guys!  I wasn't planning on using the PVC because of the burst factor.  I remember seeing it a friend's garage several years ago and remarking on how dangerous I thought it was!

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.
