Hello!

We're having a standby generator installed. Generac 22kw. Requires 306 cuf/hr at 7" wc. Generator will be 100 ft from meter (calculating 130 ft gas line to account for elbows and the like) Gas company upgraded service to 2 psi.

Installer said they'll use a 1 inch line (2psi) to the generator and have a pressure regulator to 7" wc then a short 3/4 inch pipe run to the generator.

Will this be sufficient? The Generac install guide calls for 1-1/2 for that length of pipe but I don't think it takes into account the higher psi.

Thanks

I'm a Cornell sophomore that's super interested in getting into gas scheduling and maybe trading in the future. Obviously, Shell, bp, and Exxon all have their corporate internships (mainly for rising juniors/rising seniors, ex: bp internship to IST program), and they don't appear to be scheduling-specific. Do people know of any other oil/nat gas scheduling internships?

This result of a "Gas Pipe Line" in web search and I was puzzle what is the thing in red suppose to be for? It is look like it is not suppose to be there. I ask the AI and its mention about Vibration damper and shock absorbers but I still doubtfull on the answer so here I am asking the community about it.

I have this valve on my deck, and I’d love to be able to hook my griddle up and stop filling propane tanks (a natural gas conversion kit is available for my griddle). This thing looks pretty rusty. Is that normal for an outdoor pipe? Inside the house the pipe looks brand new. Should I have it replaced? Who would I even call for that? HVAC? Plumber? Thanks all!

Is there anyway to disconnect the pilot lights on half the burners?

Setting gas pressure on commercial range. Data plate calls for 5” man pressure. My question is- would that be set with oven and range burners on? Just oven? Or everything off. I know on fryers we set manifold pressure with fryer running.

I have a 92k btu rated fire pit that will be connected to a 1/2” quick connect hose that’s 24’ from the exterior stub on my house.

Inside I will need to run new piping to the stub out. Right now I have a 1” pipe that gets reduced to a 3/8” pipe running down the wall about 6’, then 90s in to about 3’ of additional length before connecting to my gas dryer of ~20k btu.

If I were to T off of where the dryer is with a new valve and run I would need about 5’, a 90 up the wall, and then about 6’. So roughly 11’ additional to connect to the stub out.

I was thinking of replacing all of it to a 1/2” but if my math is correct (is it?) I’d have 6+3+5+6+24 = 44’ of new 1/2” pipe to supply approx. 112k btu of appliances. According to the chart 40’ yields me 81k btu at 1/2”. Would one be satisfied with this? And/or even notice and restrictions from a 92k Btu on ~81k flow?

Or is it better to run a 3/4” up to the stub out so it would be something like 20’ of 3/4” (247k btu) and then do 1/2” somewhere in the middle for the dryer and then a reducer at the stub to 1/2” leaving just 24’ of 1/2” outside (approx 100k btu). Now idk where the restriction here is there but I assume take the lesser value which is still more than the first scenario of 1/2”?

Be kind lol. I’m also likely not doing the work - just want to be prepared to ask/suggest for when it’s to be completed.

On my property I have a drilled Well that I aquire water from daily to do all necessary things that much be done with water. Several months ago my well water turned just as rusty red as it could possibly get and it has never cleared back up. I have been told that on the other side of the hill where I'm located that a company had been drilling natural gas wells and that they could very possibly have fracked into my water source. This company did not notify the homeowners on my side of the hill of the drilling they were doing. So I have no clue what company it was and have no water samples to provide of before their drilling activities. Who is or where is it should I say that I need to contact to get help with this situation? The water I've been in left with isn't even fit to give my dogs to drink. I really can't afford to hire a lawyer at this juncture and hoping you guys might know what I can do without having to lawyer up right off the rip.

My electric stove went out today, thinking of ordering a gas one. Can I turn off a supply line right here?
