Plumbing for natural gas ???


Here's a recent thread where we covered the basics of sizing gas lines.
Natural Gas

Of course, you need the charts in the code book, but this thread should help DIYers understand the process. If anyone needs a hand sizing pipes just post a question in plumbing and I'll walk you through it.

Well i thought you wasnt allowed to comment per: your insurance,

Well here it goes, my first joint, was a 2"X2ft, incased in a wall sleeve to go through the foundation since that is what the gas go needs to connect to, then i ran a reducer(bell reducer) to reduce from the 2" to 1", then i added 1 joint(10ft) to that, then an elbow(to make a corner) then 2 more joints of 1"(20ft) then another elbow(90%)then i added a 1"X1" nipple then a and then a reducer to reduce the pipe from 1" to 3/4" then i added one joint(10ft)of 3/4" then you will never guess what i done, yup i added another 90% corner, then a 3/4"X1" nipple then another reducer to reduce my pipe to 1/2" then i ran another joint(10 ft) of 1/2" then yup you guesses it another elbow(90%)then a 1/2"X1" nipple to a union, then a (4ft) section of 1/2" then a elbow(90%) then a 1/2"X4" nipple incased in a wall sleeve to get my service live back outside to the furnace, which is very nicely popping up through my newly poured concrete foundation, with a concrete sleeve,then i added another 1/2" union, then a 1/2"X2" nipple then a 1/2" brass ball valve, here i will attach a 2ft section of 1/2"stainless stell flex line to make the run from the ball valve the to the gas valve inside of the furnace.

Not to shabby for an 8th grade uneducated dummy!!!!!!
I had no help doing this project(skilled craftsmen), and this was my first black pipe installation project!

Your pipe should have been sized based on the btu/h input rating of the appliances being supplied, as well as the distance from the meter to the farthest gas appliance in this house. Without that information, it is a shot in the dark as to whether or not it is sized correctly.

Also, I hope you air tested your line for leaks before gassing it up.

What do you think i am a dummy just cause i am uneducated? Yes it was pressurized to 105 psi, the soap water sprayed on every joint!
Heck i could of tested the way i used to in the old days, wait till the gas is turned on the run down the line with a lighter!
Im not kidding thats how i used to do it! Ng is at such a low pressure when you do find a leak it burns no more of a flame then a struck lighter!

Relax. Nobody called you a dummy or insinuated that you are. Those are your words.

As for flame testing natural gas piping, that is pure ignorance, and to even suggest that it is a viable means of leak testing is nothing short of irresponsible.

Thats the benefit of living in the woods, no permits required for anything, not electrical, plumbing, hvac, structural, architectural, The only permit required is a remodel permit but only if the individual project exceeds 50% of current market value of your home!!! Get it--------- individual project!!!!!!! So limit the size of your project not to exceed the 50% mark of the current market value of your home!

Hey I know that no one called me a dummy, nor insulted me, i just found it funny that i would be questioned of that nature... Sorry if i misrepresented myself in that comment!
And wow, what a repsonce to my method of inspecting for leaks in the old days, Again them were old days before i becam ea little educated in what if....... Didnt take long to figure out not a good idea, and yes air is a much better alternative to NG.

I finally got to fire the system tonight, no heat yet couldnt get rescheduled till tomarrow at 12noon for gas-ng turn on, but the a/c if fully operative and blowing like i have never been blowed before... All my problems are now resolved for lack of pressure in the system, My bedroom used to be 105% degrees(seriously) and 85 in living room, and 75 in kitchen, rear bathroom would be just as cold in side as outside, judging by the mass/flow of air coming from the vents at equal pressure ii do believe that most or all of my issues are good to go.
So if i have any heating issues tomarrow after gas-ng turn on maybe i can holler back at you folks and get some input. If i am still welcome.

Ignorance is not having the knowledge of' and stupidity is having the knowledge of' and not using it!
I am really fond of this saying, this reallly does apply to me in the nature of which i choose to do things, back in the day i used to do some pretty ignorant things( but because of lack of knowledge for the situation) now Most everything i do is done fo ra reason, and done with knowledge!
But dont get me wrong i am only human, so stupidity does play a factor!!!(sometimes)

DVLCHLD' I am so sorry for jacking(hijacking) your post, it just dawned on me that this was your post that i kept on responding in. I am sorry but i managed to keep returning to this thread for the purpose of comments posted to me, and continued to post in here as if it were my own thread!
I do hope you can except a sincere apology from me MrShadetree0222
As i am truely sorry for jacking your thread, wasn't very nice of me, and not my typical behavior..

Plumbing for natural gas ???


No biggie. It's all educational. I'm going to buy 4 wall mounted natural gas heaters. One medium sized one for the main living area, smaller ones for each of the two bedrooms, and an even smaller one for the bathroom. The house already has all these but they are very old and we would like two of them in slightly different locations. I have another question. I have one old gas pipe that does not have pressure in it. It comes out of the wall, runs along the baseboard about 2 feet, then goes through the wall into the next room. When you open the valve there is no pressure at all. If I use a hand held grinder with an abrassive metal cut-off wheel to cut this pipe off at the wall is there any chance of the pipe having some residual gas product in it? I'm pretty sure natural gas doesn't leave any residue in a pipe but I'm still nervous about using this tool to cut a pipe that use to have gas in it.

Idunno, as much as I might diagree with a code official on on an issue, I am still glad they are there.

If there ws no official local oversight building safety would be in as bad a shape as the subp-prime crisis.

No Ng doesnt leave a residual but to over ensure your safety and everyone around you then go ahead and turn the system off at the meter, and find your furthest thing in line and burn it till it dies, to guarantee no Ng left in the line! That would be the absolute sefest way to ensure your safe before grinding or cuttig or whatever measure you choose to do the removal! But why not just trace the line backwards and remove it that away? Trace it backwards, remove the line-in, and cap what ever might eb left behind wether a "t" or an elbow or what ever feeds the line you wish to discontinue! Just my 0.02cents worth!

Does the state fire marshall Know about you?

He should if he doesn't.

You are telling people in an open forum to place a flame in front of an old gas pipe.

BRILLIANT!


Then i guess we could always say "I didn't know the gun was loaded". That is the same logic you are applying with an open flame.

If you go back and re-read the post you would see that-that was a an act of ignorance(Ignorance is not having the knowledge of', and stupidity is having the knowledge of' and not using it) in my past before i became more educated about the dangers of testing live gas-ng lines with a lighter! now this is a help thread for the purpose of helping DVLCHLD, now if you wish to bash me feel free to do so in one of my threads or in a private message, but keep your negative comments about my ignorance from younger days, out of this mans thread!
And what you never in your entire life even as a younger youth made a misjudgement, endangering your safety or the safety of someone elses life around you?

Post 27 you say to hold a flame on the open pipe til it goes out.

Even with a gas meter closed off this is a dangerous practice as the meter valve seat may leak by even slightly. Inside a pipe it be comes a bomb.

So I am not bashing you I am calling into question your practices dealing with NG.
