A lesson about iron pipe as a plumbing material - Intro to Plumbing Systems 

There are not many videos that describe iron pipes in such a clear manner. Thank you so much for this!

This was tremendously helpful as I was making repairs to a water heater, and needed to know about the pipe union fitting.

Good job with explaining iron piping...clear, consise and easy to follow & understand. 👍🤝

Just found this channel. Great info and very informative. I hope you continue to publish these videos.

Thank you I’m currently taking this course in my plumbing apprenticeship program and this helps a lot. Blessings to you

Just found you . Very informative . Comfortable speech speed (not too fast ) you get extra high marks for not having kids, animals, or music in background. Your audience can then get the rich content w/o those distractions.

nice, will be looking forward to more of your videos.

Wow. Thanks for the clarification about pipe vs tubing related to diameter. BTW your pronunciation is very good making your english easy to understand for non english speaking. Merci!

Thank you for this. Glad the gas water heater has a union fitting.

You are awesome! so happy i found you today😎

Excelente video, muchas gracias, saludos desde Venezuela.

Several things to correct. You could take this videos advice and get by fine. This is more nitpicking than anything. Galvanized is perfectly legal for gas. So is brass for that matter. Coastal areas use it because it holds up better in the sea air than black iron. This is why you put a drip leg before each appliance to catch particles. Also, bushings are illegal to for gas but not for water. I always thought this was odd because water runs at much higher pressures than gas. Though I guess water isn’t as dangerous if it leaks. The last thing is just a nit pick. He said that pex and copper were measured by OD whereas steel pipe is ID. This is incorrect. All plumbing pipes are measured by ID. HVAC labels their copper by OD. In plumbing you have two two designations for OD, IPS (iron pipe size) and CTS(copper tubing size). All pipes will fit in one of these. Steel pipe, brass pipe, pvc, and cast iron are all considered IPS. Copper, pex, and cpvc are all CTS. Though the size is nominal on some. Copper tubing is actually 1/2” ID. Pex however has the same OD but a thicker wall so it’s slightly smaller on the inside.

Awesome Video. Thank You

good video. guy has a pretty nice looking shop, and the bandaid makes it authentic. pipefitters with clean smooth hands are untested

Good explanation !!!

Excellent video!!!

You really made me to know the best work

i'm replacing a valve that has no unions with a valve using a union on both ends. i noticed when taking the union apart there's a shoulder that fits within the inside of other side of the union to seal the fitting. when removing the valve by unscrewing the two unions you have to create at least an 1/8 of an inch from each union in order to pull the valve out. how do you create that clearance to remove the valve? hope this make since.

Thanks good explanation 👍

so useful thanks

so useful so thanks

Well done!

Awesome video talking about fittings. I have an old home with the galvanized color pipes for natural gas. Can this be an issue?

What ball valve can install on galvanized pipe ?

New subscriber here. I just found your channel. 👍👍

What is your opinion about connecting galvanized to pex using brass pex adapter ? I am concerned about dissimilar metal connection and corrosion. If you don't suggest such transition - what is the other way to connect old galv pipe to new pex pipe?

Can you tell me how to put a ball valve on galvanized pipe without threads ?

In plumbing, copper pipe is measured by inside diameter. In hvac, it is measured by outside diameter. That's why hvac techs call 3/4" copper 7/8".

I’m studying this at the moment in College , and I have an exam in this the coming Thursday 😁

Thank you.

I wish to know does a union has a particular direction to mount if the fluid would flows from the right to the left?

in the demo brass values were connected to iron pipes, will that work in real life? corrosion?

Very helpful. The only thing I can do to show appreciation is hit the like button and subscribe. I hope others will follow.👍

Sir , first your way of speaking is best, people all around world can listen and understand you, giving time in between your words. Sir in our village home in mountain our gi water pipe broke. What should be the distance between two 1/2inch gi pipes, so that we can join them by union.

question, can pipe sealer be used on the sealing part of a gas pipe union. the matting ends ?

Thanks..❤

If I can make one observation , copper tubing is measured on the ID unless you are working with ACR tubing which is measured on the OD. Otherwise your videos are done nicely. Don't know if your a plumber or pipefitter by trade.

You did a good job; except telling us how to align a "union". And I have found this on all video's I have seen. So does it mean it can be left to right or right to left. Or doesn't it matter. Especially working with Natural Gas unions. Which I am doing now. I NEED to add a union; on a pipe carrying natural gas; that I want to go to my new Generator. So do you put it this way or the other way? Or doesn't matter. Please respond.

Very interesting. In regards to gas, I've seen that the gas company uses yellow tubing (different sizes), similar to PEX. Can that be used in a house to run the gas lines? When we had our furnace converted from propane to natural gas, the gas company ran the yellow tubing to our meter. The guy who connected the meter to our furnace used black iron pipe. It seems it would've been simpler to use the yellow tubing.

Thanks

Can a galvanized cap be used to cap off a gas line with black pipe?

What's the difference in the black pipe, iron vs. steel? As long as it's black pipe, and either made out of iron or steel be used for natural gas?

you can use black iron on CLOSED loop boiler systems....

Wow!!!

What about brass pipes?

"Contrary to popular belief, natural gas does not adversely react with the zinc coating on galvanized pipe" -International Code Council, G2414.4.2 (403.4.2) Steel

Firefighting pipeline installation videos please sir 🙏

8:30 union fittings

Does gas really react badly with galvanized steel?

👍

I didn't hear you say that the all the fittings for the black Iron pipe are black Iron, for a clear understanding.

Hi sir,am paul,am kenyans.am your student,how can i reach you.

No teflon tape for gas, only water

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-vTDUsjaMKTU.html this is how to detach used plumbing materials

Why no one talks about gas valves😢

onlly OGs call it pipe dope

The made in china stamp on all those fittings is a damn shame. To those adrift on their yachts who are to blame for this: we see you and you’re house of cards is coming down.

Man, I have so many things to say about this video so I will sum it up with this. You shouldn't teach anyone about plumbing, especially gas piping.

No

Great video!!
