Gas Installation; Must See.

in THE MAIN WALL
we have been using it for decades here in the twin cities. two pound gas systems all over and copper drops off of steel for alot longer. There may be some places where the gas quality doesn't allow it. John Lampard and Ray Knobloch are two of the guys who championed the two lb systems and have helped to right the national fuel gas code and both are here in the cities and both are known by me. All of our two lb systems are run in nothing but copper, although many are now starting to use the Wardflex and like products since they have just been approved here in the last year or so

    is it

    typical in the UK to use copper pipe on a gas line with soldered fittings. Seems like an accident waiting to happen even if it was properly supported.

    pvc

    notice the plastic piping going out into the rain leader. I wonder if the gas and pvc goes to heaters?

    You're right Aidan

    This truly needs no comment. Good for laughs though. Hope they weren't trying to get more than 5-10,000 btu's through the pipe.

    It is typical

    .....for domestic installations, although usually better supported and soldered. Less liable to leak than screwed steel, IMHO, although obviously less robust.

    Compression joints aren't recommended and are only used where soldering isn't practical. I don't see a problem with it; in a fire I'd think that if you weren't out before the gas pipes failed, you probably weren't going to get out.

    Do your codes require you to use steel?

    The gas pipe was the supply to a cooker.

    Copper is taboo on natural gas

    In the US copper is not approved for natural gas. I think it has something to do with the sulphuric compound added to make the gas smell. This sulphur attacks the copper.

    Yet, the brass fittings survive.

    It seems serious enough that pamphlets that come with the gas bills always warn that if the meter reader sees copper, he must issue a warning and disconnect notice.

    Also, in the US plumbing codes obsess endlessly about venting your drain lines from each point of use. Way more than just from the stacks which is typical in Europe.

    Of course, when you plumb everything into the downspout, you've got the best venting possible.

    No doubt, interesting pictures.

    Propane?

    I recently had a propane system installed for a cooktop. They used copper through out. I assume copper is OK for propane?

    Not here, but close

    I can't use brazed copper, but Lincoln Nebraska can two hours east of me. I've heard also that gas varies and makes a difference. Kevin

    The gas must be greener where you are

    Our utility makes a big do about this copper thing. They also insist old (brass?)flexible connectors for appliances should be changed to ferrous ones.

    Amazing, I wonder what they put in our gas that is so bad. I never imagined it would be different elsewhere. Thanks for making me wonder.

    We've had the stainless Wardflex for many years now. Underground lines can be polyethylene.

    Commercial hook ups run at 11 inches of water. This is much less than your 2 PSI which is around 50 inches of water.

    Go figure.

    we have bottled gas quality here

    I'm sure quality makes a differance and yes we have to use stainless for appliance connectors otherwise soft copper. 2lb systems scared the h out of me when I first moved back here. Had been in NY before and that was steel accept for appliance drops and only if totaly accesble. LP was of course all copper because of the quality differances. We had some areas where the gas was so contaminated it would soot up a gas fired boiler much worse. than any of the oil burners I ever worked on. I beleive the wardflex is approved almost everywhere now and you all will be seeing 2lb systems in the next ten years or sooner. It is coming. You can run the whole house main off of a 1/2 inch line and then header off in the mechanical room with indavidual branches. Real nice set up
