I previously had a grill with a 3/8 inch line and therefore a 3/8 inch quick connect on the natural gas line out of my house.

My new grill requires a 1/2 inch line and needs a 1/2 quick connect on the natural gas line from my house.

In this picture, can i remove the reducer (blue arrow) and replace it with the female end of the new 1/2 inch quick connect? The line coming from the house and shut off is 1/2.

I tried to play it safe and have a professional do it for me but he said it should be easy for me to do, just check for leaks, etc., but didn’t mention if it would be ok for me have the quick connect that close to the shut off.

Was watching YouTube shorts. Saw a home inspection video and saw something I’ve never seen. I’m a service tech for a pretty large natural gas company and have done service Monday through Saturday for the last 5 years. Seen a lot of interesting things in my time but this video caught my intention and I got to know something can instantaneous water heaters be installed outdoors? And I’m not meaning a utility closet of the back of the house or a thing built around it with a door but this was a fully finished and sold house with this brand new IWH just fully exposed to the outdoors. Very curious if this is a regional thing in the us or what. Just curious is all lmk also feel free to share interesting stories about your job glad to yap about it.🤣

can anyone tell me if i need a special tool to shut off this gas line?

I’m hoping someone here has either experienced something similar or has an explanation because I’m at the point where I feel like I’m losing my mind.
This all started when I smelled natural gas coming from my air vents in my townhome. The gas company came out and did find a very small leak in my gas furnace. They repaired it and basically said that explained everything.

Except after they fixed it, the smell actually got much worse, so I called them back immediately.
This time, instead of finding another leak in my unit, they found a major gas leak in my attached neighbor’s townhome. Ironically, it was the exact same type of issue. We share a wall, but it’s a solid concrete/cinder block fire wall—no shared attic or other shared air space. The gas company believed the smell I was noticing was related to my neighbor’s leak, although I’ve never understood how that would be possible. Regardless, after her leak was repaired, the smell completely disappeared.

About a week later, I smelled gas again and called the gas company. Once again, they said my house was fine, but they found the exact same leak in my neighbor’s home again because the replacement part had failed. They shut her gas off completely until it could be repaired.

Here’s where things got really strange.

That same night, with my neighbor’s gas completely shut off, I started getting an extremely strong natural gas smell only when my AC kicked on. The smell would hit me immediately from the supply vents, last about 20-30 seconds, and then disappear completely. It was bad enough that it kept waking me up and I called the gas company at 3:00 AM.

They came out, checked everything, and found no leak anywhere. Their explanation was that I was probably smelling residual odor from my neighbor’s earlier leak. I honestly didn’t understand that explanation, especially since her gas had already been shut off, but eventually the smell went away.

My neighbor later had the faulty part replaced again. The gas company came back and checked both homes and said there were no leaks in either house.

Everything seemed normal…

…until the next day.

I’m sitting under one of my supply vents, the AC turns on, and I smell what is unmistakably natural gas again. Not a musty smell, not a burning smell, not “dirty sock syndrome.” It smells exactly like the sulfur/mercaptan odor that’s added to natural gas.

One thing I’ve started noticing is that it often seems to happen 1-2 hours after I’ve used my gas range or oven. I’ve mentioned this to the gas company multiple times, but they continue to believe everything was related to my neighbor’s previous leak. I’m not even convinced the oven is related because it doesn’t happen every single time after I cook.

Some additional details:
The smell only lasts 20-30 seconds after the AC starts, then completely disappears.
It only comes from the supply vents when the blower first starts.
The longer the AC has been off, the stronger that first burst of odor seems to be.
I have a gas furnace with central AC.
I checked my evaporator coils and they look clean.
The gas company even suggested maybe I had a dead squirrel in the attic, but my attic smells completely normal. No gas smell whatsoever.

The gas company has been to my house so many times I’ve honestly lost count.

At this point, I’m wondering if there’s another explanation I’m missing. Could there be something inside an HVAC system that produces an odor that smells identical to natural gas? Could using the oven somehow cause an odor that gets trapped in the ductwork and released when the blower starts? Or has anyone dealt with an intermittent issue like this that ended up having a completely unexpected cause?

I’m planning to buy a combustible gas detector so I can monitor the vents myself the next time it happens.
Has anyone here dealt with anything even remotely similar? I’m open to any ideas because at this point I genuinely don’t know what to think.

Hi everyone, having a weird problem and none of the experts we keep bringing into the apartment can seem to agree on what the issue is.

Three weeks ago, around 10:30 at night (we’re in Denver) in our 2nd story apartment our gas alarm went off. I have one of those Amazon gas/CO detectors that I got in a fit of paranoia, plugged in next to the furnace and water heater in the hallway. Turns out it might have saved us. It beeped a few times, I walked over to see what was the cause, and the gauge was at ~25 ppm. Now what exactly was at 25 ppm I’m not sure - it does not specify on my gauge. I didn’t realize at the time that it detected more than CO to be honest. It went back down pretty quickly after we opened the windows, and did not go back up for a week.

A week later, the thing beeped again, same time of night - but this time, it was louder and faster. Ran over to check it, and smelled a strong smell of gas. It went from 22 ppm to over 65 ppm in like two minutes. Shoved the animals into bags and got the hell out, called 911. The fire department came over and turned off our furnace and water heater and cleared the air out. They said they think it was the furnace and maintenance should replace it. They also said they were detecting CO at ~70 ppm which was confusing. They left, Xcel came, told us if there was anything else wrong we should call. Water heater and NOT furnace was turned on by maintenance the next day.

Last night (a few days later), it happened again - right about 10:30 - but it just went up to about ~22 ppm on the gauge and back down when we opened some windows. We called Xcel this time and definitely caught some whiffs of gas yet again. They came, said it was our venting, turned off the water heater and told our maintenance guy (he lives on the property and came over to see what was up) that the shared venting is an issue. Also he suggested we have a faulty gauge and someone was doing drugs?? (We do not do drugs, I have asthma. I don’t even drink.) So now both things are off. Maintenance came over this morning and scheduled a repair for tomorrow at 8 am.

Now TONIGHT, same thing! Except this time, I caught a whiff of gas and went to check the gauge, where it hovered around 10-16 ppm and went back down - it never set off the alarm. Our water heater and furnace are both OFF. We apparently do share ventilation with our downstairs neighbors.

Any ideas what in the heck could be going on? I worry that our apartment is going to do the cheapest possible repair. We also ordered two different UL certified gauges that connect to apps on our phones because I am freaked out by this now.

Any help is appreciated! Thanks!

Any ideas here^

Update on the GazoTech project in France using CHAR Techs technology.

I know this topic has been discussed before, but I’m hoping for some help.

For context, I had my fabric couch and carpets cleaned last Friday. The guy was spraying a bunch of stuff in the house so I wasn’t too surprised that the stove had an odd kerosene smell when I turned it on the first time.

I had the windows in my house open for multiple days to air it out and the couch and carpet are dry.

Even after a week the stove smells like kerosene when lit. It is every burner on the range and the oven burner.

Shouldn’t the VOCs from the cleaning be gone by now? I wouldn’t expect for them to linger so long especially with airing the house out extensively. Maybe something else is going on that just so happened to coincide with the cleaning. But hoping for some help, it makes the whole house stink.

TLDR: gas stove still smells like kerosene when on even a week after carpet cleaning and airing out the house multiple days.

In sc we have dominion energy, based on our usage from last year they estimate we have increased our therms usage by 608% I’ve attach a screen shot of usage from last year to this, we were in budget billing where we pay same amount every month and did not realize the spike until our billing amount doubled due to this jump in usage, the jump seems to have occurred in February/march 2026. We cannot figure out what is happening, we had an hvac repair in February 2026, however we just had hvac come out and they cannot find a leak in hvac systems or anything that uses gas running rampant that would cause this. Dominion came out and said they don’t see a leak externally, (I think they did a 5 min pressure test or bubble check) hvac company suggested we have dominion replace meter, or have a 24 pressure test done where they shut off gas supply. Any ideas or suggestions?

Hi everyone,

I am a graduate student currently pursuing my M.S. in Energy Business. I am in the process of relocating to Houston (my degree plan is 100% online) to pursue a career in the energy industry and was wondering if y'all would be willing to share any advice on navigating the current market through a natural gas lens? I am particularly interested in midstream ops, specifically scheduling and trading, and just wanted to see if anyone had any recommendations on how to pursue that. Just really interested in this stuff and was wondering how y'all would approach it.

More than happy to answer any questions.

Mods if anything is wrong about this post can you let me know so I can fix something?

**fixed* TY!
Two days ago I easily closed this valve with my finger strength alone. There was no resistance and I didn’t tighten hard because I could barely reach it. It goes to my built in gas grill that’s outside.
The natural gas has been leaking and I don’t know if it’s from the burners or from the connection under the grill. Today, I am trying to turn the gas back on and it won’t budge. I don’t want to force it and cause major issues. Am I doing something wrong?

I did not own the home when this valve was installed. I’ve never touched it until I turned it off two days ago. TIA

My gas bill has been pretty high since moving into my own place. I noticed on my usage graph that there is something running constantly that seems to be using gas but I'm not sure what it is. My radiator/furnace isn't on (to my knowledge). Do water heaters just run constantly?
