A spinning planet, add in a little bit of alcohol, and before you know it you end up with crooked pipes.

Thank you for your input on this matter. Just to reiterate, my caution stems from the ongoing litigation my friend is involved in due to the ground settlement pulling the pipe down and breaking the line inside the house. This is precisely why I raised the issue in this discussion—to leverage the collective expertise of this group. Thank you once again for your insights.

That had nothing to do with how the fuel system was piped above ground. That has everything to do with how the piping underground was not properly bedded or the gas meter was not anchored to the foundation.

Again, all these things go into me recommending a “swing joint”. It provides the necessary flexibility to accommodate soil movement and prevent stress on the gas line, thereby avoiding potential damage.
You continue to demonstrate lack of knowledge about fuel piping or threaded pipe in general.
You do understand that “flexibility” in threaded pipe means you are loosening a joint that is supposed to be tight. Steel fuel pipe is not designed to support underground fuel pipe settlement. There’s no such thing or should ever be any flexibility in threaded steel pipe.

Thanks, He is not going through it. He pointed this out, the builder didn’t do anything. The pipe broke and the gas line was spewing gas in the home. Could have been a lot worse if it exploded.
If that is the case, could you explain the diagram from earlier in the thread?
A lot of replies in a short time.
I don’t call that out. Heck, around here, the meter can be almost sideways before the gas company will do anything. No leaks…all good…move on.

What case what diagram?

That’s an “opinion” document.
Can you show me in the IFGC where it says a swing joint is used to relieve stress on fuel pipe.
Now keep in mind when you start moving fuel pipe you start loosening joints.
I have to ask. What is your experience with gas pipe? You seem to think you know more than the plumber, builder and inspector.

The inspection today was an 11-month warranty check on a new build. During the inspection, I found that the builder had neglected to install the ridge vent, there were broken floor trusses, and disconnected gusset plates. I am not suggesting that I know more than the builder, inspector, or any other tradesperson. However, people do make mistakes. As I mentioned earlier, I have firsthand knowledge of this issue which could have caused a serious problem.
Just curious, is there any special way for installation in areas which have seismic events? If not, every gas line would snap if they were straight piped into the structure.
Yes, the use of approved hangers such as wire hooks. This is why there is often an appliance connector before the steel pipe is attached to an appliance.
Not required in my area, however, some gas utility companies do recommend/require it. Find out from the gas utilities in your area how they want it:

Interesting, apparently the are other people that [quote=“Martin Willes, CMI, post:25, topic:249412, username:mwilles”]
demonstrate lack of knowledge about fuel piping or threaded pipe in general.
[/quote].
It’s very common sense in a swing joint when one joint goes up another joint goes down. This means one joint gets tight and the other gets loose. That’s called a gas leak.
It’s not just me that’s saying this. It’s your builder. It’s the authority having jurisdiction. It’s the local plumber. You’re flying solo on this. Now, if you’re only qualifications are a home inspector, those three entities I just mentioned above are going to feed on you like a shark on a baby seal.
Comment for the report. - Offset appears stressed. The gas line arm has reached maximum length. Further settlement may put strain/stress on the gas line and may have a potential for leaks or damage. Recommend further evaluation to ensure the gas line is properly secured and installed to modern standards.
