Nice Video!
Note to all beginners. All unions must be accesible. Can not bury them in walls. This basement application was perfect for a union.
man I cannot thank you enough. this is totally do-able, solves so many issues and answers so many questions. thank you...thank you!!!
Thanks for a clear and concise video without needless dialogue. Much appreciate you posting this video!
+Happy Camper - Right on! Thanks for the comment! 😎👍🏽
Thanks for the great video! It helps so much to see it done before starting a project myself! The video is really clear, easy to see, and nice and fast! Thanks!
+ElementofWorship - Wow! Thanks for the kind words! Glad it helped out 👍🏽
Awesome teaching video, learned a lot. You covered a lot of aspects of working with this pipe. Thank you!
RUclips and the master tradesman: Improving the world one awesome video at a time.
Talk about executing the plan to perfection! Daaaayum. You certainly know what you are doing sir. Thanks for sharing.
great video, was a big help for me when i tapped into my existing pipeline. The union was a big help, i wasn't sure how I was going to unscrew my pipes and screw them back in until I saw that part of the video. Not sure why people didn't like the video.
+Lauren Hanahan - Glad it helped you out! You know you can't please everyone especially on RUclips. 😊 Thanks for the comment!
Is that what it’s called? What he uses to make the last horizontal connection? Looks like large hex nuts making a connection.
It's funny... It's like I was sitting describing the work I needed to do to move an existing gas line in the basement, slightly over to allow for a whole house water filter system to be mounted where the well water comes into the house. Fabulous video and great job! Thanks for sharing this!
+Michael McCrimmon - Right on man! Thanks for the comment! 😎
Nice job, I love plumbing.Thanks for sharing.
Excellent video, my main concern was clearing the line before cutting. Thank You
A tip for you. When using a pipe wrench, adjust the jaws so that both jaws and the heel of the upper jaw are touching the pipe. A three point grab. That way, you'll not egg shape the pipe
+richard wysham - Good tip! I’ve rounded off plenty of galvanized water pipe trying to remove them to tie into. Not so much black pipe but I can see where it would help to stay on point with the jaws. Thanks for the comment!
42, thanks for sharing this. Lots of us don't use a pipe wrench all that often. Nice to know this. Thanks.
How do you feel about those new auto pipe wrenches? I like my old heavy ones but I’m stubborn.
Awesome video. Just what I needed for reassurance of a project I am working on. Thank you!
Thank so much for your great details video
Good clean video. Thank you
Nice job - you made it look easy.
I just want to let you know that I watched this video, installed a gas line to my duel fuel 12000W generator, had it inspected. All before Dec 31st which allowed me to qualify for a $500 dollar rebate here in California. This video in no small way made me $500.00 bucks! thanks again man!!!!!
You made that look easy. I learned a lot. I hope you do more stuff like this! Thanks RemodelGC!
That's the plan!
As a gas journeyman I would give your QC a 95/100. Excellent job! The only things I would have suggested: Don't use pipe wrenches on brass or the unions when a crescent wrench would have been a better choice, and also never touch the meter without checking for electric first and then add temporary bonding cables in case the line is energized. For you DIY guys, you can tell this guy is a pro!
+Mike Carroll - Right on! Good suggestions for our DIY friends! Thanks for the complimentary comment! 😎👍🏽
Also you can save time by tightening the last fitting instead of doing them all separate. (ex): your last tee you did you can hand tighten the nipple valve and plug all and just put a wrench on the plug to further tighten them all at once. Good vid and glad to see you wipe your joints. Be safe
You are Pro Sir
Danny Combes no. Do one fitting at a time and you will know they are all tight. Don’t tighten the furthest fitting.
A pro would know to use a three quarter bite to avoid egging the pipe.
Thanks for posting this. This helped me finish our gas line. Nice video!
Oh, Thanks for watching! Glad it helped out!
Such a great song on this one, I actually played it on repeat at my wedding, everyone loved it so much that now all my friends have it on repeat in their cars and when spending time with their families. Just brilliant.
Almost 6 years later and I still come back to this video for the song. I leave it on repeat when I go to sleep at night. This song was also playing on repeat the whole time my wife was giving birth. The kid turned out a little screwed up, but the wife was very appreciative to have such good music to keep her spirits up during the whole process.
generic country rock is very expensive. Don't make fun of the fact that he could only afford a 50 second snippet and had to keep looping it. When I drive to work, I can only afford a 20 second loop. But it does the job. It gets me there.
That connector is the magic. I was thinking there must be a T fitting for retrofits with a reverse thread on one side to allow simultaneous tightening. But then it would require a reverse thread cutter to mate up one end of the cut pipe. Thanks for making this video.
Awesome ! thanks for the entertainment 👌
What are the chances of explosion from the sawzall and residual gas in the pipe?
Great video and love the music!
That music would make most elevators puke.
Great Video -
Excellent video! I was wondering how to tie into my existing gas line to run a small feed out to my attached garage for a small heater.
Outstanding!
buen trabajo...Piping excelent work
+Ricardo A. Sánchez Vásquez - Muchas gracias, señor! Thanks for the comment! 😎
Excellent video
+Paul Muzio - Thanks for the kind comment! 😎
Buen video!!!! Felicidades!!! Saludos!!!
excellent video
+Antony Cabral - Appreciate the kind praise! 😎
Thanks I've been wondering how to do this I was about to take all the pipes loose lol
Amazing work man! Your technical prowess and fluidity in working with gas pipe is evident and you evidently have great skill in the art of gas-fitting. I appreciated that your video was in real-time as you've also written above, which is more like "in the act" alongside your shoulder watching, so to speak. Super work. Respect.
+Pegasus444 - Wow! Thanks for the kind comment! 😎👍🏽
Looks good though.good work cool video.
+Greg Troy plumbing - Thanks for the comments! I'll have to try those left right nipples some time thanks for the tip 👍🏽
Nice work, what is the best way to release the pressure from the pipe?, I need to shut off the main valve of the house and reduce pipe line to fit new water heater in a little closet, I appreciate any help thanks
Thank you!
Good video. Is it ok to use brass male into iron female. I've taken out a bayonet gas hose and free standing cooker, and putting in a gas hob using one of them yellow gas hose adapter.
This video help me gracias 🙏
Band is nailing the fake-out ending
Nice job and proper use of your pipe wrenches. Just a question, could you have just used a bell reducer instead cutting the pipe line and replacing the tee???
Very helpful video. I have an unused gas pipe in my basement that I would like to cut and remove. Was concerned about sparks from a reciprocating saw. thanks!
+Tbird 62 - Reciprocating saw blades don't make many sparks if any, use a fine tooth blade. But definitely shut off your gas at the meter and bleed (open) the line before cutting it. Thanks for the comment!
RemodelGC Thanks! I wondered if that's why you took the yellow connector loose, to bleed some gas out. Helpful stuff!
I didn’t think it be safe to cut existing gas line with gas present in pipe. Was it evacuated out before cutting?
i've been looking for a way to tie into an existing gas line for a long time thank you.
I'm about to switch to tankless in my garage and need to get into attack to see where 3/4 changes to 1/2 for my current water heater. However, Rheem notes 1/2 inch pipe is okay....for lower BTU? . Is it possible 1/2 is acceptable for a short run of pipe? I may have to cut into pipe just like you did, but yours is near an elbow allowing room to work. How would you do it if the pipe went another 20 feet?
Also, in California, the code states the order of items is: shut off valve, sediment trap and then flexible connector. Thank you.
Can I add a line either from the hot water tank or the furnace to go into the kitchen for a gas stove?
what was the purpose of increasing that lines volume for the same single fixture, probably not demanding more that 40k btu's?
I was entertained.
How do you get rid of the gas inside the pipe before you cut the gas pipe?
What do u call that splicer? The purpose of that is so u have pipe to screw and fit between 2 other existing black gas lines that are not moveable. Thanks
Nice vid man, i have to cut into my 3/4 old gasline, im afraid to use a recip
Never thought to break the blade for tight quarters 0:25, awesome.
all that work and you ended up with the same thing you started with
he changed the pipe from 1/2" to 3/4" - not the same thing
@@SJAndrewbsme ok lol same result. Changing the size pipe at that point accomplished nothing
@@emeralddragon2010 if you are adding a larger water heater or larger oven, you may need a larger flow of gas to supply the larger burners. We are putting in a commercial oven in our kitchen and it requires min 3/4” supply. Our has came with 1/2 off the main trunk line. I am making this exact modification.
@@SJAndrewbsme what kind of an idiot puts a commercial over in their kitchen lol
do you blow out the gas line if you are cutting pipe in the house that had gas in it before you started
I can only imagine the colour full metaphors used with the task involved ...!
Nice. what about wall mount points to anchor the pipe? Oh, and testing for leaks?
Home improvement stores sell for about 6 $ small bottles with a non-corrosive liquid that one applies on the joint and if there is a gas leak bubbles will be noticed easily. Pipe shall be anchored if needed, some places do require metal ad hoc supports (from stores), and in others wood hangers ok.
Thxs great video but quick question? Before u used the sawzall to cut pipe. What did you do to make sure no gas was in line? I assume turned gas line off at meter. What else did you do? Just do not want create sparks and start fire. Thxs
I made sure the gas was off and then removed the closest valve to where I was cutting so all the gas could escape. If you use a fine tooth metal blade it doesn’t make sparks like it would if you used a grinder! 😉 Thanks for the Comment!
I was always told to not cut it that way. It’s not going to kill u if it pops on that small of a line, but it could damage the gas valves from over pressurization on ur other appliances.
Did you check lock up on that riser after you activated the gas company’s riser valve? No value after the meter I guess?
I have to do he same thing as you just did. I have a question and hopefully you will understand my explanation of this. So my main gas line coming from meter is 3/4'' and has a T fitting at my old tank water heater that I'm replacing with a tankless. The T is 3/4'' coming into T and the other 2 legs are 1/2'' one going to water heater other continues down the line to supply stove. My question is the 1/2'' that supplies my old tank water heater could I just use a 1/2'' to 3/4'' adapter and run 3/4'' line to new tankless heater?
Your old T have one 3/4 for main line and divided to two 1/2 so just use new T for tow side 3/4 and one side 1/2 .
Curious why you had to take out the pipe all the way back to the original tee? I'm looking to do something similar and was wondering is there not a bushing that could have been put at the base of the original pipe going to the unit that would have upsized it from 1/2" to 3/4"? Was it just a design choice to make the change at the original elbow?
That's a lot of dope!
For everyone or there make sure you are using a natural gas rated pipe dope. You can use a lot of dope like he did but you could also use less. The pipe dope is not making the seal or at least it should not be. Should be a mechanical connection between the national pipe threads that's making a seal. The pipe dopes just there to help lubricate the threads until they can make it seal.
Thanks man, helps a lot.
is there no way to insert a new section without a union? I have to join a run that will be inside a wall. Where I am, no unions are allowed unless accessible. Only way I can figure is use csst to connect.
And of course, pressure test!
Teflon tape then pipe dope. 👍
What brand and type blade did you use to cut pipe
I just built a 20' x 17' deck. I wanted to run the gas line from my fireplace out to the end of my 17' deck. This is my first time and didn't realized that I purchased 1/2" pipes instead of 3/4" pipes. I planned to hook up my BBQ grill and 2 burner stove. Do you think the BTU will be high enough or do you think I need to buy the 3/4" pipes. It will set me back about $80 in cut pipes if I have to get 3/4" or you think it's okay to just go with the 1/2" pipes. Thank you for anyone's advise.
+Cong Nguyen - Rule of thumb is always go bigger in pipe size when adding length to a line. You can try your 1/2" pipe and worst that will happen is your grill will just be starved for gas and may not heat as much? You can also search for gas pipe calculators on Google to get a better idea for length to btu conversions. Good luck!
@@RemodelGC As I understand it, starving an appliance of gas due to an undersized pipe has two problems. First, as you say, the appliance will not heat as much. However, doesn't supplying too little gas (due to an undersized line) also create the potential for carbon monoxide?
Awesome job, man. I was wondering how those brass tee connectors are being installed.
Thanks for the video, great detail on how to do this work. Curious - was the union just to make the assembly easier? (I already read in other comments that it was up to code). Thanks again!
+David Hollman - Thanks! The union was because I tied into the middle of line and it makes it easy to tighten it all back up. Some say you can use a left right nipple but in the northwest unions are legal in accessible areas. Always check your local codes before attempting any work. 😎👍🏽
Just curious, video appears to cut into pipe and replace an existing pipe, did I miss something?? One video I watched mentioned the sharp pipe wrench teeth potentially piercing through brass shut off, his preference was crescent wrench. Is that being picky? Thanks for taking the time to do!!
david never use pipe wrenches or anything with teeth on brass. always use crescent wrenches
what was done.......seems as though the line is the same as before............
This just helped me so much , shows you can use a compression fitting so you don't have to take a part the rest of lines , because there all threaded , so some one like me who want to run gas out to my garage I have cut just like he did , add a tee and add union fitting to the other side.. with out having to un tread the rest you can only spin into one side , leaving the right side unspin able , bc its already tight in place .. unless you un tread the whole run ... very help ful awesome video
@@davidfrisch5538 if you aren’t a plumber don’t do it.
Went from 1/2" to 3/4" down
@@davidfrisch5538 you cannot use compression
@@otisbigsby it's already done .. I ment to say union
It has a very high level of safety
Looks good next time put more supports
Ryan Jeffery If he does that, will you put more punctuation.
Sir,
Correct me if I'm wrong but couldn't you have gotten the same results by not cutting anything & just using a 3/4 FNPT X 1/2 MNPT Bushing at the existing in line tee, then coming down with your New 3/4 inch pipe?
The problem was the line to the left goes to a gas log and right was the meter before the drop both lines are 20+ feet and you would have to disconnect it all to add that fitting. Unless there’s a way to do that with out disassembling or cutting I’d love to see a video on that. 👍🏽
yes sir
I was increasing the pipe size to a generator in a new install. 3/8 was not going to cut it. Stepped up to 3/4. Taking the pipe off we actually broke the 3/8 pipe with very little effort!! Eventually that pipe was going to break. Especially since it would have a little pressure on it every time I might disconnect the generator. I watched the installers put it in on the install and had no inkling they over torqued it like that.
There is a lot of discussion on the use of the union joint vs left/right nipple vs none of them. Yes, the local code may dictate do this or that, but from an engineering standpoint as long as the LR nipple is sealed tight or the union is readily visible (for checking for possible leaks) both methods are legitimate to use.
As a master gas fitter that is the only way to do it correctly
So how much extra horsepower did you gain
Question. I have gas in my tiny house. The builder split the black pipe to run from my stove and there's a black capped metal pipe outside where the w/d hook ups are. How do I get the gas out? I think I need to add some kind of fitting to connect a yellow line.... and is it something I can do myself? Tia
I always recommend having a license professional look at what your doing it’s worth the cost of your safety if it’s really as easy as just a fitting sure take photos and possibly you can go to your local box store and they should be able to help you. Good luck!
Other than using a pipe wrench on a brass fitting, nice job. Adjustable wrench would've been a better choice.
Great Vid, I'm installing a line from my "main line" into my kitchen to replace an electric stove to gas. The line is an inch I believe and stretches from where it comes into the house to the utility room which is on the other end of the house. The main line goes right under the Kitchen. My question is, Can I cut the main (like you did here) and put a Tee in right where I need the gas line to the stove or should I run a line all the way from the Utility room which is about 20 feet away?
Another question is it OK to reduce the gas TEE from an inch to half inch right away or reduce the inch Main line to 3/4 then half?
Thanks
Bill
+Bill Carroll - Thanks Bill! The reason I cut my line was I needed to continue the 3/4" line to a new tankless on demand hot water heater I was upgrading to. If your trying to get a 1" tee exactly where you want you'll have to cut out your line between connections and install a union or a left right coupling to adapt your new fittings too. 1/2" to a stove is usually ok! Thanks for the comment!
So I understand your comment, it is OK to cut the main in the middle of the house to add the TEE? After I shut the Main off at the meter how do I drain the pipe of Natural gas to avoid any sparks and fire?
+Bill Carroll - I always recommend you have a licensed gas fitter look at your project before you start cutting your gas line. If your not comfortable working with natural gas lines I suggest having a professional check it out.
Thank-you for the Vid everything went great and new stove is in place and operational.
Also, I have this ringing hissing sound coming from my water heater. When I turned off the pilot & flame the sound stopped, I tried to turn it back on and the pilot will not light, the 4 or 5 small pipes leading to the water heater have caulk sealant stuff melting off.Is the problem that I need to reseal it on those pipes, will the pilot then light and be fine after that?
+PlanckTime - I always suggest you seek a qualified gas fitter to work on your gas piping. Please read the many comments on the video as a lot of people have asked the questions you've addressed. Thanks for the comments 😎
Good work, I just don't understand why. You have the same exact configuration as before, but with a union. Couldn't you just have left it the way it was?
An extra $300. That's why.
He went from 1/2" down to 3/4" down. No way to get the tee off to increase diameter without cutting the horizontal run.
The pipe was the same before you did this..was it just for demonstration?
It's a old video but you put white paste on pipe , white is for water pipe line's , yellow paste for gas line . Is it still holding up ???
I don't understand what you gained by cutting the line and adding the union connection. Before it was a solid line with a T going down. After it is a line with a union going down with a T. Same ending. Am I missing something?
Was this vid just to add a union? It looks the same with added parts
At 4:05 you attach a piece with a large nut on it to a small, threaded piece of pipe. Do you know what that is called?
Instead of the picture saying " oh no, i cut into the gas line", It should say " oh no, I am using a Ryobi"
cryobi
RANDOM STUFF
Lol, I was unsure what brand that even was. If it isn't yellow, red, or orange I can't tell them apart. Ryobi? Hitachi? Kobalt? Idk.
The most impressive part of this video, he cut off the reciprocating blade short to get the cut accomplished.
Lol
Tobin Bybee That's not correct. The blade came just like that out of the pack.
The sediment trap should be as close to the appliance as possible. Not sure if this is code everywhere though.
I like your video looks like you are in Journeyman plumber
So you cracked open the closest outlet to allow any excess gas out of the pipe before you use your saws all correct? That way you had no ignition of gas in the line?
If it ignites what's gonna happen?
@@latenight6815 maybe a trip to the hospital. :) Or possibly the morgue.
But imo if it does catch fire the worst that will probably happen is any residual vapors will ignite and shoot a flame (briefly) out of any openings in the system
@@stinky817 probably true... as long as there is no active supply. The way some of these fear-mongers talk on here that someone will totally blow up their neighborhood and everything all the way back to the gas companies supply and then the gas company!
4:17 I'm left handed. Is it okay if I removed dope from container using CCW strokes? My instructor said, always apply the dope using clockwise motion, but CCW is easier since I;m a lefty.
+birdwing98 - I was taught to fill the threads completely. I guess I never thought about which direction I went. Maybe try practicing clockwise to make your instructor happy. Thanks for the comment!
birdwing98 it only matters with ptfe tape. Must be clockwise or it will unravel when you thread it.
i thort JBG travels was on by your music in your RUclips
I'm sure I'm missing something here but what was the purpose of cutting the line up above?
+Alowishis - Sometimes you need to add an appliance in the middle of an existing line or in my case, I needed to increase the line size from 1/2" to continue the 3/4" to a on demand hot water heater. Thanks for the comment! 😎
gas valve should be before the drip pocket so the gas can be turned off before empty the drip pocket
Drip pocket will never have to be emptied
I'm about to repipe/reroute my entire basement, so I can drywall the ceiling without burying any pipe. There is an 8 foot length of 3/4" pipe between the outdoor meter, and an indoor union. Everything south of the union will be replaced. Sizing calculations suggest that the new configuration should start with 1" pipe. Would it make any sense to increase the pipe size downstream from the union, considering that I will leave the first 8 feet alone?
+Greg Roman - Typically you would start with a larger pipe first and branch off smaller. I think it defeats the purpose of going larger after a smaller pipe? But don't quote me on that? 😎 I would probably just replace the first 8' to be 1" to start. Don't want to starve your appliances of that Gas! Thanks for the Comment! 👍🏽
Thank you for responding. Your video was very helpful, by the way. Seeing the steps you took, in proper order, is worth 1000 words.
+Greg Roman - Thanks again! 😎
Cool video, I learned a lot. However I didn't think wiping the excess pipe dope all over the wall was very professional.
it looks like a trailer park so it's okay
whats the name of that fitting you added to reconnect existing pipe? i need to do that exact job at my house
+50sikstang - it's a gas pipe union fitting Home Depot or Lowes usually have them in stock. Thanks for the comment!
Black iron pipe Coupling
Any chance you could speak during the demonstration
Maybe I missed something here.....tying into gas pipe to ADD another appliance? U cut the pipe and added a union.....???? I expected to c u add another "t" ?
What is the fitting called that you installed in the cut section of pipe?
Union
