Hi, We're not talking about out on the street here we're talking about in your home. You can buy specialized gas pipe, but nobody ever does, and you are not enforced to use it with in your own home, however plastic and push joints are forbidden. You can't emagine soldering gas pipe, well what about when it was all lead then. As explained in a previous posting you must perge the line your working on, and that's why you go for specialist training for this type of work. If you perge the gas line you will be absolutely fine soldering it. Martin Webster. >From the UK.

I can't imagine that working too well as it would melt in a fire. Now what I can't figure out is why plumbers in this area use galvanized pipe for gas. It is my understanding that the gas will eat the galvanizing away, create an acid in the process, and corrode the pipe. Not to mention it will send particles down stream and clog up appliances and whatever else is connected to the line. And don't plumbers look at the line and assume galvanized line is for water/air? If that's the case, they could be in for a trip to the moon, along with the city block they are in.

I ask because here in the United States, I can't believe that soldering "any" gas line would pass code. ----- Original Message ----- From: martin webster To: blindhandyman@ yahoogroups. com Sent: Saturday, April 26, 2008 15:52 Subject: RE: [BlindHandyMan] do you really want to be a plumber? Hi, The most accurate way of testing for leaks is with a water or digital manometer. At the gas meter and within a gas appliance there are small brass plugs which you use for perging the pipe work and appliance of gas. These are all so used to run pressure tests. you would undo one of these and attach your manometer and repressurize the line. Once the line or appliance is at it's required working pressure, *usually milly bars) you would then shut off the gas and watch for pressure drop. if there is a leak even a minnute leak, you will see the water drop down the scale on the manometer. My sighted girl friend checks the manometer for me. There are all so really good gas leak testers which are hand held and audible, and there's all so your nose. I have both manometer and gas leak tester which I can use to go round any joins I have soldered. Of course I have a nose too, but the manometer and tester are much more accurate, the tester being able to detect as litttle as 30 parts gas per one million parts of air which is the industry standard, the tester is of course variable and the manometer being able to measure pressure in milly bars, so both pieces of iquipment used in conjunction with one another is the way a gas fitter would do this. The manometer for testing a whole line or appliance, and the tester for finding any leaks. Tip, when replacing the brass test plugs use a little gas ceal. This is like a grease which gas fitters use, and it's all so good for insuring a good ceal on the rubber hose that attaches the manometer to the line you are testing. The test that Cy speaks about is known as the old match test and indeed is a reliable way of testing for small leaks, the danger with this test is you may get a build up of gas, and you can have a flash I do know of people who still use it though. The flash point for gas or a build up of gas in any given size room is five percent. Hope this helps.

To: blindhandyman@ yahoogroups. com Date: Saturday, April 26, 2008, 6:59 PM David, Now, I know you are going to think that I am a liar - but - one of the local plumbers tests for leaks by lighting a rolled newspaper and passes it around the new connection. The first time I saw him do this I was headed for some other place to be! I suppose that so long as there was not a build up of gas this is probably safe but, no thanks folks. The soap you spoke of is something like Dawn dishwashing soap. It will do a great job of bubbling up if there is a leak.
