I Installed Flexible Gas Line From Home Depot... (It Leaked!) 

4 years ago I watched this video when you first dropped it, I am getting ready to run the gas line for our house and the first thing I thought as I started to research the process was that I needed to come back and watch this again. Still a great video with lots of easy instruction. Thanks.

I have to install this stuff at the family cabin, never used it before. Thanks for the guide!

Very educational. I may not be building a house like what you did, but I’m learning a lot of stuff which I will use in the future to fix something at home.

Thanks for sharing RPR! Really impressed with your professional and clean install! Good stuff. Cheers from Motown!

Red Poppy, no problem at all mixing electrical stuff. You just can't mix it in the panel you have to use the right breakers. Using different boxes or outlets doesn't effect anything. Use it and save yourself some money.

Great job......it's really starting to take shape now.

gotta love it every one knows exactly what u should've done!!!! I think you are killing it stay after it brother

As long as got it inspected and your local inspector is happy. All good.

When we built, we figured we would only need propane for the stove and water heater as well. We used only wood for heat for four years, but then we had to use electric heaters when we were out of town, and when everyone was sick, it was real hard to tend a fire with the flu. We ended up putting in a Empire ultra efficient space heater that actually heats the entire house, and now we can use either/or. It's nice to have the heat come on in the morning without stoking the stove!

With floor joices that close together you might as well use wrought/black iron pipe and fittings. Plus it helps to use a fine metal file around the cut edge for a better seal.

My first real job at 17 was plumber apprentice. My mom was dating a master plumber. It was new commercial plumbing. I wish we had that gas pipe and PEX for the water back then (1980). Tracking down and fixing the leaks on all the black steel pipe fittings was a nightmare. You are doing a great job. I'm plumbing my house by myself right now, also. A lot of the tricks are coming back to me, mostly after I do it wrong. LOL

WOW - that gas line story was crazy - THAT could have been a disaster - glad it turned out ok for you Bro !!

So glad no one was hurt and also awesome that the color codes saved you... note...

2 years ago they announced going to robot arms instead of moving slag manually...assuming the tractor you mention was part of it being moved manually. Not exposing employees to hot slag is a win, but some will probably complain it's a loss of an entry level job despite a tech to operate the robot being hired.

Your vid is very good, I know for a fact that it is a lot of work, but you actually make it look relaxing and satisfying. Very clever how you minimized the leak risk by not using fittings on the turn going to the water heater. I noticed that you strapped the pipe at the T for the black pipe going outside, also noticed that there was no siding on the exterior walls with it means that: "if vinyl siding will be used on this application" nails will be used for that. What is the recommended clearance between the OSB and the gas line to guarantee the siding nails will not perforate the pipe? Thank you.

awesome job good luck with your build !

Just for future reference you should use a little pipe dope over the Teflon tape when making connections. It reduces friction between the tape and the threads which allows for a much better seal. For proof back out a fitting with just Teflon tape and you will see most of it is bunched up towards the outer most threads. Also you will notice much less force is needed to tighten a fitting when using pipe dope with tape. Due to less friction.

When I worked at a plumbing company we had to do gas line repairs in trailers down in the crawl space with all the black widow spiders. We would pressurize the system and pray to god we would see no soapy bubbles on our joints and connections under there, and that the pressure gauge never moved.

I wish I could make a find like that. I'm working on an out building and I need some electrical stuff!

I see that you use a knuckle buster wrench to tighten fittings. I call them that because if it slips that is what will happen. regular pipe wrench is safer. Main thing is that you do what works for you, and that the finished does not leak. I prefer to use black pipe, and flex only at the connections, but that can take longer. Also you can leave the line under test for longer than the specified, but not less. Also that is a great idea leaving the gauge on the line. Also I use NG in my home, and that never goes over .5 lbs.

I would or have like to see a close-up preparation and installation of the fitting. Fittings are money too, but as an auto tech who had serious surgery got stuck working for UTI. They bounced me from room to room teaching as $12k a year made it hard to keep instructors. They just found that I had 5 years as install & diagnostic tech for a local HVACR company. Many classes from manufacturers but before the stainless flex was invented and sold. It’s funny to think of the family farm where my younger brother and I took turns shooting food cans we sat on the 2k propane tank behind the garage in the early 70’s. Strange to think a new house, pour concrete basement with 3 bed, 1 bath and sump-pump cost $26,300 in 1963. Oh ya, they used copper pipe back then from tank to appliance drops.

Love this guy, find Peace or die trying. Keep grinding

Nice, i am going to pre drill holes in my rafters for this stuff.

Also you could have used the stub out 90° elbow with square metal mounting plate that's welded together, and the flexible nail guard slinky above the gas tite connection near the stub out.

I would run a spot for a furnace may be in the future you want to put one in, the line would run, On the other hand one less leak to have on the line too

Thank god for channel locks , another pliers mechanic , two wrenches for tightening pipe!!

I was a mechanical inspector until 3-08. I never signed off one initial rough inspection because not one person would install csst in concealed locations per the manufacturer's installation instructions.

Up here in Ontario Canada every point you have a Connection they make you put a trap. Is it the same there? I imagine that it would go outside of the drywall. That yellow stuff looks real nice to work with. I know working with black pipe can be a real treat. It looks good things are going fast. One step closer to the prize 🏆

Excellent video tutorial! Almost everything I needed to know for what I need to do! Thanks!

Thank you for the great video. Using this on my remodel.

Propane tanks on ag running gear are common here. Might be useful as the nonprimary tank (multiples not run in parallel here) if the supply truck will only meet you at the end of the gravel road. Old NH3 tanks can sometimes be converted.

The end cuts are crucial on flex gas lines the yellow plastic needs to be cut back as well as cutting a smooth end to the stainless a pipe cutter is recommended as the brass ring just pulls the face end up against the brass taper for the seal.

Be very cautious using any with rubber O-ring seals within. Parker is a brand that uses brass on stainless to deform the end to a flare that is automatically flared when the fitting is put together. There are a few brands that utilises a rubber O ring internally to complete the seal. That may be ok if and only if that fitting stays in an area that is accessible and repair can be made. When in doubt a solid mechanical seal can't be beat.

Another great video...enjoy watching your progress

You make it seem so easy, nice to see a guy beat the high costs of tradesmen and still do it right. Great video and info.. thanks for the lessons.

So, the ceiling connection, was the run too long for a single run pull with one person? Or did your bought length make it necessary to splice two pipes together somewhere anyway? Sure glad you knew enough to know there are different Teflon tapes for different applications. Great job! You're getting closer and closer to "move in day".

@Red Poppy Ranch Heath, I have been with your channel since nearly the beginning and I do remember when you found that windfall of electrical components at the dump, I'm still in awe of your ability to find steals 'n deals! Congrats on the tractor, I look forward to seeing what you've found. When you mention the condition of the road, it makes me wonder; when the time comes for your family to move into the house, what will you do about mail delivery? Will USPS (or any other delivery company) deliver to the ranch? Will you establish an address (or is there an address already assigned) for your property?

Your description says it leaked. But you don’t talk about where and what happened?

Nice video and informative but I was taught early on in my plumbing apprenticeship; always use 2 wrenches when tightening anything!

One thing on the insulation, you have 2x4's and that does not allow for thicker insulation unless you add a second layer on the inside. Only one thing I would have done different, but it costs more is use 2X6 studs on the outside so I could get more insulation, but one way around this is use insulation board on the inside or on the outside wall as even in places where it is too dry to snow during the winter such as where I am that does make up for the cost of the insulation based on the cost of heating alone. It is possible to be cost effective in the cost of heating in just ONE year.

Nicely done.

Another great plumbing job, Heath. If you lived close, I would contact you to put in a hot water tank for me. I remember seeing a video of that road. You will need lots of gravel for it.

Most of the house fires I go on that don't go out are due to lighting strikes and this type of pipe losing its integrity through small pin holes. If your house gets struck turn your gas off and have your lines tested somehow.

This was an excellent video. It's obvious you really know what you're talking about.

With all the ladder and step work you have done in this build, you must have leg muscles like Russian weightlifter!!

code requires testing pressure to be 1 and half times the working pressure and that pressure is 14" water column or 0.505277 pounds per square inch, so your test pressure can be min 3 psi. a 1 to 10 psi gauge would be ideal.

I just did the same thing in OH. The city refused to hook up the meter due to having the yellow indoors.

Gas utility guy here. Back when this stuff came out we had manufacturer training and cert cards issued. Suppliers weren't even sposed to sell to non certified fitters. Proper sizing is critical. A given nominal id csst will not pass anywhere near the same amount of gas as black iron hence for a given flow rate csst always needs to be larger than a black iron application. Cant tell you how many I found contractor ran undersized lines because they based size on black pipe sizing charts. CSST has manufacturer specfic flow rates at different pressures that must be faithfully adhered to. The corrugations offer quite a bit of resistance to flow. Also a lot of regs regarding nail plates and partition penetrations. I think you may have misspoke about running elevated pressures in residential applications. Elevated pressure is where csst becomes way more cost effective. Typical 2 psi system allows smaller tubing to be used (cheaper) but requires a second pressure cut indoors before serving equipment.

Yes I had trouble with this yellow stuff too

Awesome video. So glad teflon is used. Hope proper pipe sizing was done. Either way, great video!

For gas you need more then teflon you should use both or at least just pipe dope usually anything over 3/4 i use both

Need to spend more time on the different connections, and hou to make them. Use close ups so we can see the actual connection being made.

geeze.... that cut gas pipe was a nightmare for you im guessing. glad it worked out. I own my small business and things like that scare me

At a previous home this same yellow flex line was installed, no stainless was visible at the gas fittings. My existing home has the same flex line and the gas fittings appear similar to this video. Just a bit of stainless exposed. A Rinnai water heater was installed later and that plumber said no stainless should be visible otherwise the brass and stainless will interact causing corrosion. All three installations were done by licensed plumbers. ?

There is a high torque requirement for seating the gasket. Much higher that regular steel pipe.

We bought a 1,000-gal propane tank to go with our 500-gal propane take so that we will have plenty for our Generac Guardian generator and so that we will only have to buy propane one time when it's cheapest in the late summer.

You're a beast pulling that pipe through all of those floor joist holes! You know they're not perfectly straight so I bet that was not an easy feat! Well done!

A gas outlet outside will let you setup an outdoor kitchen for those times cooking inside would be insane (summer) or times you have lots of stuff off the garden to prep and can. High pressure setups can also be in places for things like backup generators as they can suck down propane.

Thanks for the tips and tricks!

I’m a Tennant connecting a gas line for a furnace. My apartments main gas line is 1/2” all I have is 3/8 pvc, my buddy says it’s better to use steel and pvc is not compatible for gas. I don’t see the difference 🙄 My question is the 3/8 is too small to fit the nipple. Is it acceptable using the pipe tape to build up the smaller plastic pipe and thread it on the larger steel gas pipe? It gas checks with no leaks and plastic won’t spark. So far the heater has been phenomenal. If you want a recommendation for a wall heater pm me. Peace.

So u mean that u can use this flexible gas line in walls I was told it was not recommended & that I shouldn't..👍👍👍nice work

I see you have a Laundry Room. That's going to be a lot of laundry for five children. I was wondering if Cedar could use a propane gas dryer. Anyhow, great job going on! p.s. the AltE RU-vid site really breaks down how to size a solar system. The video series (22) I am referring to is called "Off Grid Solar Power System Design." If you watch the first five videos, you will know how to size your entire system. I am taking notes right now. This series is a Golden Nugget in solar design. Amy Beaudet also shows you how to hook up the system in some of the other videos of that 22-video series.

You must be grateful for having professional plumbing experience!

Good video, I use CSST quite often. Be careful with the red o-ring, real easy to cut it sliding over the end of CSST. Only one question, doesn’t CSST require a ground clamp on one end of your run? Better check codes, and what’s required by the manufacturer. Another suggestion, use wrenches not channel locks, right tool for the right job.

I learn a bunch watching you sir. Thanks for that. The electrical is what I've been waiting for. :) Keep up the good work!

tell us the story about that evacuation!!! I'm invested in that story! *subscribed*

thats a lot of almond joys back there

The maintenance men at my factory use yellow pipe dope made for propane and natural gas for connections.

Check with your state the yellow CSST from Home Depot is not approved for use in Massachusetts, even though it’s up sold in Home Depots here, I have had to pull it out Of a few jobs where it was installed and replaced with the black coated track-pipe.

The end of the CSST should be taped over before pulling it. It only takes one fleck of wood or dirt in there to clog your gas valve some cold winter night when it is drawing hard. Pushing open pipe through joists and studs is a bad practice.

Most all propane lines inside home run ½ pound of pressure. Or is measured in 14" W.C.

Only suppose to tighten 3/4 of a turn after getting it hand tight. I have to do 20 for 20 and never fail a test. never leaks when installed correctly. Over-tightening will ruin the gasket and cause leaks.

How did you split the line to both appliances? Just use a T? Did you run 1/2" to the range? Do you up size the main supply line one step above the lines out to the appliances? I'm running one line to a cooktop and one line to a set of fireplace ventless logs.

Hi I enjoyed your video, I have a question did you install a 1”inch gas pipe or 3/4”inch gas pipe in your house

Hello great video I have old gas line that should have been removed at the of renovation . How do you bleed gas from the line safely thanks

Very informative video - pleasing to watch, Thanks for sharing!

So am I right in thinking a propane tanker will come down the "Road of Endeavour" and fill your system periodically? With your skills you must have thought about heating a water tank with heat from the wood burner, and save on propane. Why did you not do this, I'm curious as to your thought processes? Always a big supporter, wishing you and yours the best.

maybe old but just looked up the cheetah system i dont like it maybe because im old fashioned in my 40's but for a do it yourselfer it cld be alright. like how a master plumber feels abought shark bites but if i ever found all that i wld grab it tho use it in basements or other places i cld change it out easily. if you used it how did it work out for you?

Holy crap 25-30lbs?! That's insane, most systems where I live are .5 to 2lbs max! Main lines from gas company is max 50lbs.

I wouldn't think the inspector would allow a gas appliance under the stairway. I enjoy your videos.

Would you have drilled a larger hole maybe and insulate the gas line from the wood with some foam just so there’s no wear and tear maybe no creaking sounds just thinking out loud thanks for the video

It funny how people tell you what to do not knowing the local code. Do you have to have systems under pressure for inspection. Can't imagine that sewer with water in a freezing conditions.

i have heard you cannot put that type of pipe behind drywall in Michigan.....is that true?????

To the people who watch this and try to do yourself,you have to run a # 6 copper ground wire to the the ground in your breaker box from the gas line.could have lighting run into the line and a arc a hole in pipe if not grounded.

Run a line to the yard for a bbq's or a firepit while you are going this.

Do you what the MAX test pressure for this Home Flex (fittings) is? My guy installed a gas system on a new house with a lot of black iron and mixed with some 1/2” Home Flex for the bbq and range lines and test gauge is leaking off slowly and we can’t find a leak anywhere. He tested at around 40-50 PSI when he was trying to get the leak to show and I’m now wondering if he may have damaged the fittings if there only rated at around 30-40 PSI. Thanks for any help.

That whole you have to use a certain color of Teflon tape for each type of material I'm not a firm believer. I've found that white Teflon tape works well for any type of material unless your current code requires it.

With most CSST installation the holes drilled should be 1.5x the OD of the CSST used. Check installation manual

Nicely produced. Is that 1/2 or 3/4 inch?

I wonder if you could put this in conduit and run it to like a garage if you wanted to put a natural gas stove in your garage under the ground if anyone nose can they let me know

out of curiosity mate, on the T piece where u have your gauge if for any reason u have to disconnect the gas pipe can you do so as easy as a compression/soldered fitting or you have to first disconnect the T going through the wall first then turn the whole T piece?

In the USA you have to be a license contractor to install any type of gas line as well as proper training in all different type of materials that you will use. When I run into a new product I make sure that I understand the way I'm suppose to use the new material. I've seen plenty of mistakes from handyman and wanna be plumbers. Good video and I like your advice for others that don't know. Thanks for taking the time to do this.

Thank You 😊

Can this yellow gas line be used for “natural gas” in my house? Of course right now I have black pipe but I want to relocate the gas line for a stove remodeling her kitchen

Off grid electricity but gas dependency? Please let me know what you're thinking. I'm cornfused

Didn’t know you could use flexible...thought it had to be black iron!

I don't think you need to crimp the ferule with your channel locks. They get compressed by tightening them together with a wrench. Other than that, Good vid!

I want to run some underground to my patio area. Cannot find any vids on this but I plan on putting it inside schedule 40 to protect it. Any advice?

With that first tee I just assumed you were making a drip leg. I thought why is he putting that drip leg through a hole in the wall. It took a second for me to process it. It’s interesting how many variations there are on gas pressure testing considering there’s only two codes. Some places only require a little over the operating pressure. I’m in Austin and they require 30 psi for 15 min for low pressure systems and 60 psi for med to high pressure systems. Gas tite is pretty expensive stuff but it definitely is nice when you need it. In your case where you have to go between joists and only have a couple of fixtures it’s wonderful. If you were paying a plumber, you’d make up that extra cost by saving on labor easily. However when you have houses with gas dryers, water heaters, furnaces, stoves, etc. and everything is under the house or in the attic, it’s definitely cheaper to use black iron especially with mega press. We’re not allowed to secure gas tite in the wall except where the stub out is. The reason is for nail protection because it’s so thin unlike black iron. If it’s allowed to be loose it will be pushed out of the way by a nail or screw but when it’s secured it will be penetrated.

Dude.....you look like NASCAR driver Clint Boyer !
