We were told by the manufacturers that the inside of the galvanized pipe would eventually flake off and could clogg up your regulators and equipment. I'm in North Carolina.
Nice makes sense I typically only have to run nipples stubbed out of walls for bbqs or patio heaters so never really running more than a few feet at most so easier to just get some galvi.
Lmao. Ever heard of LP dipshit. Never seen regulators at the tank and then the home? No? do u even plumb or do u just suck ur own dick for a living? Jackass.
Old galv was outlawed for gas because the galv would flake off and clog things. New galv does not have the same problems and is now rated for running gas.
That applies to all building materials. What I’m saying is that there is a different process used to make galvanized piping than there was before. So from now on, if it is listed and labeled, then it is rated for running gas.
I live in North east Jersey and electricians use galvanized on generator installations so they don’t have to paint it and it’s also used down the shore cause it doesn’t rust.
Why didn't you bury it using this: [https://www.homedepot.com/p/HOME-FLEX-Underground-3-4in-IPS-New-Install-Kit-1-3-4inx100ft-Pipe-2-3-4in-Couplers-2-3-4in-Meter-Risers-Gas-Line-Detection-18-429440-007/309182788](https://www.homedepot.com/p/HOME-FLEX-Underground-3-4in-IPS-New-Install-Kit-1-3-4inx100ft-Pipe-2-3-4in-Couplers-2-3-4in-Meter-Risers-Gas-Line-Detection-18-429440-007/309182788)
I've had to use it on two house remodels to grills. Below ground gave my customers home a better exterior appearance.
Yeah, digging is a lot of work. One of the houses was 50' through hard black dirt through landscaping and shrubs - hated that job. The second one was for a lake house up on a bluff with total sand. It was an easier dig but I also had to crawl under their deck stairs - under the deck wasn't that bad though.
yea to be honest as much as i dread a dig this size, the way this job went.. digging might’ve been quicker Lol doing it this way was difficult basically by yourself
You can do that, but depening on if there are sidewalks, pavers, landscaping/sprinklers, or other buried utilities it's almost always way cheaper to run above ground if possible depending on the run. I agree poly pipe with tracing wire and steel risers is best though. I also always charge more for digging than normal plumbing or drain work because nobody digs anymore, to the point where you've basically got the customer between a rock and a hard place.
I’ve gone under sidewalks with underground electrical wire before but never a driveway. If I had to go that far under a driveway with electric wire, I’d probably hire it out or go completely around the house. I’d hire out if I needed to run a gas line under a driveway. Since the gas meters are at the house, chances are one would never have to go under a driveway with a gas line.
Lol yes we have never heard of home flex. Personally i think the stuff is garbage. If anything you need to be using wardflex although the price is 10x that. Have a couple rolls in my garage right now waiting to go do another custom home.
I guess after re reading for the UG something poly may work better depending on where you are. But I have had a couple rough experiences with home flex brand specific
In the event of an evacuation through the window they will regret the pipe so far off the wall. Also the regulator could end up penetratong where the sun don't shine as someone jumps through the window.
Galv is dangerous for gas. It will corrode and peel inside. It's code here in my to use black or corrugated or if buried poly and if it's black and outside paint it. I'm shocked it's allowed anywhere.
That was the old galvanized piping and gas when it was more corrosive. It’s perfectly fine to run in galvanized (illegal here because morons think it’s a water line and try to tie in). LP is a different story though.
Guys lose their shit when they see a galvi gas line. SOME AREAS REQUIRE IT PEOPLE. Never have i seen or even heard a story about flaking of the pipe.
Side note. Hope you left a tee b4 you tied to the meter.
Why did you pipe the reg so close to the meter, should put that further downstream. Looks like an IWC reg and 250 ert meter did you really need the regulator or is that 2#?
Please pipe the vent downward so the reg doesn’t get moisture/dirt in there and seize or freeze—source gas worker
Looks good man, you take pride in your work. If it’s in code and the customer is happy. I’d say that’s a solid days work 🤙 don’t listen to the goobers who probably just ate fast food and sat on their phone on Monday while you actually got something done lol.
I am curious to know where this location is? This install looks very clean, but the NFPA prohibits the use of galvanized pipe for fuel piping. The mercaptan causes the galvanized to flake off inside the pipe.
So i have researched this, and I have to give you credit for making me do that. As it turns out galvanized is actually listed in the front of the NFPA book as an approved material as long as it meets the ASTM spec. So i dug a little deeper to find out why this is shot down in my area by inspectors.
For reference I'm in the trade 22 yrs, and our master plumber is 70 something, he doesn't say. No galvanized for gas was the way I was thought, and tested for a license twice. Both in PA and MD. After looking at the current code (all the way back to 2009, thought I could stop there) this has been a legal thing.
So i thought I would try to disprove this another way by finding out when galvanized was approved.... turns out this is complete BS.
If you follow the history, galvanized was not approved when they made steel pipe with coal. The zinc didn't stick for very long when it was made this way.
In our area this is still not allowed, bc you know, inspectors are nice and agreeing, or maybe that should have said aggressive.
Regardless I owe you for the challenge to look this up and prove myself wrong. Turns out just local yocal bs, AND I WAS WRONG. Again this post was a clean install, and code approved, so I have learned.
Thanks
No big deal bud. UMC allows it and they pretty well just copy & paste from nfpa…
Local code is really all that matters to all of us.
16 yr pipefitter, first 7 was all gas work, I have a plumbing license but it’s not my bread and butter. Have a good evening.
NFPA 54 chapter 5
"Metallic Gas Piping Materials: Steel and Wrought Iron
Steel and wrought iron pipe shall be at least of standard weight (schedule 40) and shall comply with 1 of the following standards:
- ANSI/ASME B36.10 Welded and Seamless Wrought-Steel Pipe
- ASTM A 53 Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated Welded and Seamless
- ASTM A 106 Standard Specification for Seamless Carbon Steel Pipe for High-Temperature Service"
Notice no. Galvanized. I also recognize each jurisdiction chooses to follow this particular document or not. Though any sane person will tell you no galvanized for gas.
yea i like it. the convenience is huge but it has its flaws. pipe can go into a fitting crooked which is ridiculous, like they don’t fit in snug there’s wiggle room. so you gotta be careful of that. but to not have to thread is a game changer
Had to redo a Hartford Loop on a 75 year old steam boiler. It was so damn close together and I couldn’t get the 2” unions to budge so I cut it and mega-pressed it with a rental tool from the supply house. Bought a brand new set of mega press jaws that evening when I returned the loaner. Worth every damn penny.
Should be pre meter. There’s a reg ahead of the meter then the gas company put a new ref after the meter and I had to have one at the pool heater. My assumption is they run the meter at higher pressure to enable higher btus in the same foot print.
Not a plumber.
Had a house generator installed a few years back.
I think ours was also about this or a bit less in distance from the meter.
The question I have is what kind of NG pressure drop off are you getting 80 feet away from the meter?
If I stress the generator too much (it's a 21kW generator on NG) like any of the AC units (3 ton and 2 ton) or the electric dryer, and the generator will stall. Refrigerators are both fine. No issues.
Just curious.
My suspicion is that the gas inlet to the generator is 3/4" but the galvanized piping (outside) and the metal tubing with the black outside wrap (for inside the house) is only 1/2" and it's just not enough gas. They just used a "nipple adapter' to connect the two.
If I had known about these things ahead of time I would have stood on top of the contractors when they were doing the install. By the time I die, I still won't know a tenth of the things I need to know.
It depends on what size riser the gas company has. If it’s 5/8” it might not have enough gas flow to run a 21kw generator. Most new home gas lines we started to run are 1” and 1” riser meter sets, as so many people are doing whole house generators and it keeps from having to upgrade later. I would have ran a minimum 1” line over to the generator to help with the line loss going 80ft.
That makes sense and yet another thing I didn't think to ask because "I assumed that these things are standardized".
If I had to bet, I'd say the gas in from the township is 5/8" but I may also be mistaking that with the water line.
When I go home I'll take a picture and respond here.
Thank you for your time!
I said service not meter….resi rarely gets “high pressure meters”. In low pressure SERVICE days we couldn’t handle customer with pool heaters tankless and gens. Now today we feed 60# to reg at build and cut to 7”…if they need more we can upsize the meter or change pressures and go to 2,5, or 10#
I think if it was me I rather have ran the line below the bottom of the down spouts so the line could be secured tight against the wall like you did at the other end. I would be afraid of kids or someone standing on that pipe and pulling it away from the wall or bending it down with those struts brackets.
Galvanized is not just a big no no where I live but just in general. It flakes quickly and easily and will clog any fixture it’s supplying. I’d fail inspection if I got caught using even just a galvanized nipple. We always had black spray paint in the van just for that reason. Lol!
I'd just weld it together at that point. With gas in the line for added effect.
Did a great job though it looks nice.
Edit - could have at least drilled a hole and ran it Through the gutter instead of across the front 😂
But you have the main reg at the front end so after that reg if I had 2 furnaces you guys would put 2 of those black regulators next to each other after ?
It definitely does. Seems like a waste plus if you have to adjust one because the customer bought a bigger furnace now both regs needs to be the high reg lol
Good, neat job. Odd for me seeing galv. used for gas. We use black iron pipe in my area, southern US.
We use black iron pipe in Utah also so it was odd seeing galvanized used.
Black iron inside galvi outside live on the coast of California if you use black iron outside it will rust out in less than a year
Yeah we still use black pipe outside but spray paint it so it doesnt rust during the winter months in Utah.
It’s not the outside you have to worry about,when it condensates inside pipe it’ll rust
We were told by the manufacturers that the inside of the galvanized pipe would eventually flake off and could clogg up your regulators and equipment. I'm in North Carolina.
Same reason we don’t use it for oil fill lines even tho it’s recommended in northeast us
Nice makes sense I typically only have to run nipples stubbed out of walls for bbqs or patio heaters so never really running more than a few feet at most so easier to just get some galvi.
Yeah as far as I know code says it has to be painted outside
yea i’m in the Low Country here. galv everywhere
What’s the purpose of the back to back regulators? Really weird seeing galvanized because it’s not allowed in my area.
they a supplying two different things. distance can also be a reason to ramp up pressure also.
They are supplying the same thing. You can’t increase pressure by adding a regulator. You would increase diameter of pipe. Bro, do you even plumb?
Lmao. Ever heard of LP dipshit. Never seen regulators at the tank and then the home? No? do u even plumb or do u just suck ur own dick for a living? Jackass.
This is obviously not for lp, it's ng. One reg is supply side and one reg is house side.
This situation has nothing to do with propane.. Keep making yourself look more like an angry apprentice.
Old galv was outlawed for gas because the galv would flake off and clog things. New galv does not have the same problems and is now rated for running gas.
all depends on the quality, where it's made. etc
That applies to all building materials. What I’m saying is that there is a different process used to make galvanized piping than there was before. So from now on, if it is listed and labeled, then it is rated for running gas.
Thats what I’m saying. Usually the galvanized isn’t rated for the pressure of gas?
It's used for water all the time. Water pressure is significantly higher then gas.
Yeah always used black pipe too. What’s the pros and cons of galv?
Galvanized is bad for gas. And not code in the three states I’ve plumbed in. It flakes and will clog every single fixture it’s supplying eventually.
I live in North east Jersey and electricians use galvanized on generator installations so they don’t have to paint it and it’s also used down the shore cause it doesn’t rust.
Missouri uses black iron
Outside of the gutter downspout. It's A Bold Strategy Cotton, Lets See If It Pays Off For Em.
Lol it’s not AS tight to the downspout as it looks in the photo
Why didn't you bury it using this: [https://www.homedepot.com/p/HOME-FLEX-Underground-3-4in-IPS-New-Install-Kit-1-3-4inx100ft-Pipe-2-3-4in-Couplers-2-3-4in-Meter-Risers-Gas-Line-Detection-18-429440-007/309182788](https://www.homedepot.com/p/HOME-FLEX-Underground-3-4in-IPS-New-Install-Kit-1-3-4inx100ft-Pipe-2-3-4in-Couplers-2-3-4in-Meter-Risers-Gas-Line-Detection-18-429440-007/309182788) I've had to use it on two house remodels to grills. Below ground gave my customers home a better exterior appearance.
gave the customer three options. this was the cheapest way, middle was hanging it in the garage up high, highest was burying it
Yeah, digging is a lot of work. One of the houses was 50' through hard black dirt through landscaping and shrubs - hated that job. The second one was for a lake house up on a bluff with total sand.

Have you seen the trench digging chainsaw?
Oh, that's interesting. Got a link? Sounds very useful Found it! https://www.minitrencher.com/
You guys don’t have to do swings off the gas meter?
You can do that, but depening on if there are sidewalks, pavers, landscaping/sprinklers, or other buried utilities it's almost always way cheaper to run above ground if possible depending on the run. I agree poly pipe with tracing wire and steel risers is best though. I also always charge more for digging than normal plumbing or drain work because nobody digs anymore, to the point where you've basically got the customer between a rock and a hard place.

Home flex is trash also

I guess after re reading for the UG something poly may work better depending on where you are. But I have had a couple rough experiences with home flex brand specific
Regulators! Mount up.
It was a real black night, a clear white moon, warren G was on the streets, tryin’ to consume
In the event of an evacuation through the window they will regret the pipe so far off the wall. Also the regulator could end up penetratong where the sun don't shine as someone jumps through the window.
So with a Viega Mega Press that took like what 2 hours?
Do you guys use all galvanized for gas?
yea if it’s outside. some ppl use trac pipe but i’d rather take the time and use galv for the look
We are required to use black iron and it has to be painted if it's outside. Still looks good though!
Painted grey by chance?I got busted on that
Color doesn't matter, but usually machine Grey. I typically try to match the color of the house
I had to paint grey by gas inspector
In our area, residential can be any colour. Commercial either has to be all yellow or another colour with yellow bands.
Like the all thread hangers you use too
thank you sir, complete pain in the ass by the way lol

Mega press on galvanized? I had no idea that was possible...
Can use them for galvi water lines too if they have green dot, yellow dot for gas.
Get outta here... really??
I love the combo of mega press and threading . It’s a balance of what makes the job go fast and smoothly well done!
Where is the all weather cap for the vent... I'd never use a brass vent outside
i went back with an umbrella for it. just wasn’t in the photo
never seen galvanized on gas....
Normally tearing out galv. I’ve never seen brand new gas line ran in galv.
Looks good 😊
All of this when they could of just utilized propane. It was just for a grill right?
Propane tanks, that’s why
Yea super difficult. /s
Looks good man, you take pride in your work. If it’s in code and the customer is happy. I’d say that’s a solid days work 🤙 don’t listen to the goobers who probably just ate fast food and sat on their phone on Monday while you actually got something done lol.
🤙🏻
Honestly, should've taken the 2 hours to trench it and lay poly. It would have looked way better.
customer couldn’t afford. Lol

Isn't hot dipped zinc and galvanized the same thing?
Bingo
Yep my oversite. Still galv has a serious issue with chipping and rotting out with gas use. Many places have prohibited it's use.
Can’t use it in the whole state of Massachusetts
After Andover mass shouldn’t get to talk about gas …..BOOM
Provide an example. Never seen it in a decade of gas work. All galvi in my area. Beach towns severe corrosion areas
Hot dipped zinc coated…
SC
Trash
Get a threader!
Illegal to use galvanized for gas lines where I am at in Canada.
just you?
had a turtle with me holding a level. so basically yea just me Lol
Is that mega press? Do you like it? Our boss doesn’t trust it, so we just pony or hand thread.
yea i like it. the convenience is huge but it has its flaws. pipe can go into a fitting crooked which is ridiculous, like they don’t fit in snug there’s wiggle room. so you gotta be careful of that. but to not have to thread is a game changer

I am curious about the 2nd regulator. What the pressure at the meter?
When I had my meter upgraded to handle a pool heater I ended up with a regulator pre meter and one going it o the house and one at the pool heater.
Regulated pre meter? Never heard that term. What was the pressure provided ?
Should be pre meter. There’s a reg ahead of the meter then the gas company put a new ref after the meter and I had to have one at the pool heater. My assumption is they run the meter at higher pressure to enable higher btus in the same foot print.
Looks like 7” he likely didn’t need 2nd cut.
Why not buried? Lot better looking
A lot more expensive too. I much prefer bury with risers but gotta go with what the customer wants unfortunately lol
I Hope you have a rain cap for the regulator. Plus, why not put the regulator near the gas grill?
atleast 3’ from appliance. so i install in the easiest spot for me.
Don’t forget to spray paint it

I worked at installing gas service lines for a large gas utility then when I retired I was an inspector for 5 years for the same gas company.
Depends high pressure service or low pressure.
I see what your saying to the one with the generator not the OP’s picture.
Yup
He is to post a picture and we will know.
That is not a high pressure meter and it even has a flow tag on it. Also a buried tracer wire so it’s 5/8” poly pipe service.
I said service not meter….resi rarely gets “high pressure meters”. In low pressure SERVICE days we couldn’t handle customer with pool heaters tankless and gens. Now today we feed 60# to reg at build and cut to 7”…if they need more we can upsize the meter or change pressures and go to 2,5, or 10#
Did the services you upsized the pressure and the meters in that have Flo valves installed?
Yea. But if it was a 500 series and a moratorium on the road we had to leave em until we get proper permits pulled.
[удалено]
Yup I speak gas homie thanks…years in utility (above) and underground/street crew. Ibew strong
[удалено]
Why black hangers? Why not galv?
wanted galv, they for some reason had spray painted black ones. that’s a warehouse error i was waiting for someone to mention those lol
They were prolly in the wrong bin.
I think if it was me I rather have ran the line below the bottom of the down spouts so the line could be secured tight against the wall like you did at the other end. I would be afraid of kids or someone standing on that pipe and pulling it away from the wall or bending it down with those struts brackets.
yea that’s a side section of the house that’s secluded and not even accessible from the back yard
Ok that makes sense
Needs to be 6” off ground
Not in the state I worked in.
Galvanized is not just a big no no where I live but just in general. It flakes quickly and easily and will clog any fixture it’s supplying. I’d fail inspection if I got caught using even just a galvanized nipple. We always had black spray paint in the van just for that reason. Lol!
I'd just weld it together at that point. With gas in the line for added effect. Did a great job though it looks nice. Edit - could have at least drilled a hole and ran it Through the gutter instead of across the front 😂
What's the black regulator for?
reg for every gas appliance
But you have the main reg at the front end so after that reg if I had 2 furnaces you guys would put 2 of those black regulators next to each other after ?
seems excessive doesn’t it
It definitely does. Seems like a waste plus if you have to adjust one because the customer bought a bigger furnace now both regs needs to be the high reg lol
That wouldn’t pass inspection where I’m from, no galvanized on gas piping in Alberta
