Matt, there is more than three ways (Black iron & galvanized pipe with threaded fittings, Black iron & Galvanized pipe with mega Press fittings, Black iron pipe with welded fittings, CSST, K & L copper with brazed fittings, K & L copper with yellow pro press fittings, coated steel pipe for underground installations, polyethylene gas plastic with risers for underground installations, stainless steel tubing with Swagelok fittings for high pressure (CNG ) and they have some kind of weird flexible inlaid braided PEX material in Europe).Last I checked, I think that’s more than three.
Eric did a pretty good job on explaining the mega press but he did leave out some important info, like preparation ( cleaning burrs and marking stab depth with a sharpie ) . It’s also required to go back to threaded fittings when tying in components and appliances (furnaces, , water heaters and all stationary appliances need to be tied in the old fashion way , shut off, Union and sediment trap tee) . Hope some of this information helps. My expertise comes from 35 years in the gas utility industry and in my retirement I consult from time to time when gas incidents happen.

15 years ago we ran 1-1/4" black iron as the main trunk through our 1 story home. Longer house so we opted to have 2 tankless heaters with high btu requirements. The threading and wrenching took years off my life. Nice to see press fitings becoming the norm in gas after water line fittings paved the way
So efficient

I’ve been following Eric for a while he indeed is a master of plumbing

In commercial applications press fittings have become the norm. Megapress is extremely impressive with durability. Most projects also save on labor with these fittings, the most expensive phase of the project

[ecospider]

After adding threads to black pipe with manual tools you definitely have a feeling of accomplishment. 😄💪🏽

[briancarlisi]

Manufacturers have won the war regarding press fittings in plumbing & hvacr with pushing pressed fittings to sell the expensive tool & fittings. As the plumber attested, only 10 yrs of field testing vs. 100 for the threaded fittings so we really don’t know how well pressed fittings will stand the test of time. Good video discussing the merits & disadvantages of both. Thank you.

A good thread job is a ton of fun though. Easy, straightforward, repetitive, moderately physical. Love a good threaded pipe job.
Mega press almost always makes more sense but some people refuse to spec it.

[jonathanzappala]

I had to fix frozen pipes on a radiator line, threaded pipe that had to have gone in as the house was built. The plumber used the press pipe on the repairs, so much easier than a series of short pieces and a Union. If your power goes out on the coldest day of the year, get a generator because your boiler pipes than never froze before will in that scenario!

Sizing of pipe is very important which is another value to using a knowledgeable plumber. In 1980 I installed a tankless 100K btu Rinnai tankless water heater still in use today and had to redo galv. feed at great expense to 1-1/4" to handle the size of burner. One time lesson. Ray

I need to run a line for propane underground from my garage to my house. Runs is about 100'. What's the best type of pipe to use? I do have an 1 1/4" schedule 40 flexible conduit that I thought burying then put the gas pipe through it. It would add a nice layer of protection

[apostolakisl]

Threaded has the disadvantage of only being able to add to the end. No cutting in a t without using a union and threading while in place or removing both halves and taking to hd to get threaded. Perhaps you can rent that crimp tool as a homeowner to cut in a t on black iron pipe.

[ColeSpolaric]

I'm surprised it wasn't mentioned that black threaded pipe comes sold prethreaded in 1 foot increments and 1, 2, 3, 4, 6, and 9 inch increments I believe.

[mikepol]

Recently did 3/4 mega press and found the fitting would spin after being pressed. And very easily. Is that normal? I don’t remember that happening on 1” and above

[ericwotton]

I would never let CCST be installed in my home. I personally know two homes that caught fire after a lighting strike. As an electrician I don't care how well it's bonded, you can't predict the direction of a lighting strike. CCST is a product prone to failure.

[constitutionallyconscious]

Manual hydronic versions if propress available on Amazon saved my butt for a diyer like myself.

[jonerlandson]

I'm curious as to what is sealing the compression fitting?... what material is it?...

[joshcowart]

In my opinion gas tite or csst is only good in small remodel situations. If you’re remodeling a room and adding a gas appliance it’s real easy to run an individual line over and down the wall. Other than that I don’t think it’s a good product. It’s the only product where in walls you aren’t allowed to strap it. This is so if a nail goes in it can push it out of the way
If you’re doing a complete remodel or new construction, black iron is the only way to go. I trust mega press for gas much more than I do pro press for copper. One issue they both have that bugs me is it’s so hard to make them look nice. Especially mega press. You’ll have the pipe plumb and then when it presses it will kick it off or it will come out of the fitting at an angle.

[ecospider]

I was told flexible gas lines are yellow. I found some great yellow garden hose that has been working fantastic. 😊💥🌋

[johncoulahan]

I offen chose the method and product that put more money in my labor pocket rather than the material pocket for the supply house. If I wanted to minimize labor, then why be in the plumbing business. Of course, I'm talking all other factors being equal like total job costs and time not being a factor.

CSST sucks, requires the electrician to bond the gas line and from what i heard will melt if a high enough does come in contact with the gas system
