I’m a union plumber and I was watching this and waiting for it to be wrong but it’s right on! Good job! For anyone saying this is wrong or it takes too long to do, you unfortunately did not have proper training.

As a plumber, I’m so very thankful to see people making videos about these tips. You’re very much the G.O.A.T

Thanks for laying it all out speaking plainly and to the point. Perfect.

As a person who majored in mathematics, I learned decades ago to go a tradesman to learn how to use said math easily. I've learned so many tricks that bypasses the equations and boils it down to simple math over the years. Simply brilliant. Even though I have college degrees, I couldn't live without the knowledge of tradesmen. Thanks so much for sharing.

GT, you nailed it, thank you more than you know! I do not get all the multiple-minute tutorials that could be summed up in a few minutes and yet have little to no practical help. A guy has to get to it to get the work done and your real life applications are very much appreciated. God bless you for sharing your experience

Im a residential plumber with no union or trade school experience and I use the formulas for 22.5, 45, and 60 degree offsets on a daily basis. I've found it helpful to not only memorize the formulas for offset and setback, but to download onto my phone the takeoff charts for fittings from the manufacturers. It's very helpful if not imperative to have an accurate fitting take off when using a multiplier or divisor, especially when all your holes are drilled and your using center to center measurements with large fittings. Once you understand how to apply these formulas, you'll find that its not only quicker to use math, but yields a higher quality product. I do remodels for the most part and when I start ripping open drywall to expose old work which I have to tie into its very apparent wether someone got it right by eye or cared enough to use basic plumbing math. Not only does plumbing installed by eye look sloppy, but the pipes themselves are often under stress which results in premature failure. Practice makes permanent. Quantity over quality, or "getting er dun", is nothing more than a race to the bottom. Take pride in the quality of your work, as it speaks volumes about you when you are not around. Great video by the way!

Bro, your the best I’m studying plumbing and always refer back to your videos for better visual understanding. Keep up the good work..

Awesome video, I teach a pre-apprenticeship program and I'm adding this video to my curriculum! Well done!

For anyone wondering why you multiply by 1.414. It's because 1.414 is the hypotenuse of a right angle triangle where the two short sides have a value of 1. So the diagonal measurement of a 1ft square would be 1.414 ft. And for a 1 meter square would be 1.414 meters etc.

This is a start to becoming a professional pipe fitter. 🤗 thanks pal.

Excellent explanation! I have used this at work, I have it memorized. Used to have the multiplier for a 22-1/2 degree offset memorized too, but forgot that one over the years.

I promise I'll come back to this video and take notes tomorrow morning, because now it's close to midnight and that glass of wine I had earlier doesn't help :)) Thank you for your great tutorials!

Best chanel yo. I been saudering fan coils and youve helped me alot wit ur tricks n tips. Thanks for this vid too man. Keep up the good work

1.41 greater than the straight line distance, center to center. Then reduce from centers to bell end. I remember this from my journeymans exam. Thanks Bruce Richards👍

Ooh, I hadn't watched it yet because I didn't think this was gonna be for more than just copper. Awesome!

how did i miss this one ..... another great one!!!

Sir your this video is so informative. Thanks for sharing your knowledge with us.🙏

Thank you for breaking this down 👍🏻

Best channel 👏🏻👏🏻🤗🤗 always well explained! Good work keep it up you will be very successful 💙

I do tube bending too, and you have to keep up and not lose practice. I always write my common formulas inside of my hard hat. Rolling offsets and running multiple racks of tubing around columns and beams is critical to make it look uniform.

Simple description, thanks

Thanks for that information

I had to make a huge offset on 4” pipe. I didn’t feel like eyeballing it so I came here and just sent it and it was damn perfect.

Good stuff bro. Thanks

Perfect video:) chose simple numbers so we can learn the concept quickly

Thank you

Amazing video

For those that work hanging duct work. are this formulas work the same for duct? I always struggle when it comes to use forty-fives

So helpful!!!

very informative. Imagine if you are to cut /fit pipe with a 12 inch diameter and a 6mm wall. you just cant move them around because its heavy. this is where the correct calculation comes in. thanks Go2Learn

Great. Never knew the correct and east way

Awesome video

Can you do a 22.5 degree offset please it would be very helpful

Unreal, I have re-plumbed 2 dozen HWT's in my building just because the dumbass plumbers just thru in unnecessary joints or installed multiple unneeded joints to burn up parts they had in their boxes resulting in some seriously f'ed up configurations. When I started re plumbing these lines (option to my owners in my condo building) I always eliminate as many 90's as I can ( why use a fitting the stops the water to change direction when 45's are a mild turn offering better pressure) and I've always rough fitted my pipes because I had no other way to gauge the angle. Well done!

Thanks!

Simple good job

Helpful 👏

Good stuff

Thanks explained is too good thanks

Awesome 😎

Would you do the exact same thing for a 90 degree angle and so on?

I like the super accurate method known as holding it up and eyeballing it 😂💀

I've not seen that 1.4142 trick before, very handy as a welder fabricator. Is there anymore handy numerical tips.

Is there a current link for the copper pipes catalogue? The one posted says 404 error

For some reason the copper website isn’t working awesome video thank you!

See, there really is some reason to stay awake in math class. You probably saw the Pythagorean theorem first in junior high math. Great job.

I searched all of your videos and noticed that you do not have any on bending copper pipe. Do you not recommend bending and, instead, sticking to available couplers in various angles (as used in this video)? I've heard there are benefits to bending, so curious about your thoughts. Thank you for all the excellent videos. I've learned so much (and applied it) from you!

Classes dont even show you how to do it that well thank you

Good shit

Can you make a video of how to layout cast iron in the ceiling (wye's, 45's,tee's, subtracting fitting allowances), parallel offset?

"A wall or what not" spoken like a true tradesman

Starting apprentice job before i become electrician (odd i know) so i came here before the job to ensure i have basic knowledge. Thank you

nice

Wondering if this also works for round duct

What if we don’t have pipe centers ? For example New construction in my base meant So I can’t measure from a wall to a pipe

Do one on threaded pipe

This is unrelated to the video. But what is an air gap and is it something common that plumbers have to keep in mind?

I have a question regarding the pipes being parallel, how would you factor in a height difference? Thx in advance !

Great

Does it work on spiral duct?

Also the reason why he took the time todo the math is because waste cost/equals to loss $$$ if you are the business owner. This gives you 100% no waste which in return adds/equals more $$$. You save by having no waste. Even thoe it may only be a inch or few in waste to fit the pipe in a tight place u may cut it down close to the length/size needed where u can then make a mark to where it needs to be cut. Which then will leave you with left overs which equals waste which is wasted money $$$ on not needed waste. Times that by a 1001 over a year and that little waste adds up very fast my friend which is a good amount of $$$. Hope this helps explain more to those who dont run or understand what little things help business owners save and make more $$$.

I'm going to try this with duct work. I usually use a square or a framing square to figure it.

The copper fitting link is not loading 😢

For black iron, the fitting allowance is Face to Center minus the thread engagement right? I cant find any comprehensive charts on thread engagement though. I used to have some but cant locate them. Im back in trade school and Im pulling my hair out. That Bibby St.Croix PDF has two measurements. A and R. R isnt the fitting allowance is it??

35 years as an electrician and always tried to do 30 degree offsets because the length between bends is always twice the length of the offset needed. Easy Peasy ! ( lazy electrician 😉 ) .

Nice but you forgot ea fittings sometimes have different lip depths. Which could cause u to cut short. So always make sure your lip depth is not less then the amount your going to subtract on either side ;)

C-C(-takeoff) x1.414-equals = you piece in between

1.4142 ! Have a nice day !

Anything for 3/8 stainless steel hydraulic tubing?

I used a framing square n tape measure to figure 45 offset retired welder n fabricator.

I have 45 & 90 degrees marked on my pipe bender , measure the distance and bend both without any drama .

Can you do a rolling offset please ?

Stick your fitting on one end. Stick a slightly longer piece of pipe in it and lay it over the other end. Mark where the inside edges meet. Fudge factor for the slight rotation of the fitting and small gap between edges within the fitting(this takes experience but if you always try to use math, you will never get that experience. It definitely pays off later though). Cut the pipes and you're done. Wall must be straight, mark on fitting must be centered, tape must stay on mark etc. I used to use levels and math and such, but the reality is, your eye doesn't lie, and when you do it enough, you can eyeball it with a few tricks. When the tape is at odds with my eye, I've learned to take my eye as the final decision. The tape has screwed me more than once or 500 times. Small errors within the measuring process add up, and can put you way out.

I mean is there any other way to figure out a 45 set? Next we want to see a video of a rolling 45 set. Thanks

The math never lies The only way to run pipe

Love the accent lawl

I’m completely new to plumbing. Just a preface to my ignorance so forgive me if I ask something dumb. I’m trying to get into my first year apprenticeship and I’m consuming as much knowledge as I can. So, where did you get the 1.4142? Or is that just the standard measurement?

Hi sir u vods is good but I need yelbo to pipe santer to santer

Hey Got2Learn, I once saw a plumber measure a 45 offset but he pulled out his tape, measured it did a quick math in the head and had a piece ready to cut, is there an easier way? I doubt he did all the math in less than 8 seconds

How do you find the end to end on that pipe?

Always on cast-iron right now and... A lot of deviations between floors..... Yeah 45° ahoy!!! (Beaucoup d'équilibrage/ventilation)

I like the idea that he "took the time to do the math", as if only we had a device that could compute such a calculation for us. BTW credit to ol' Pythagoras for the assist. ;)

I would actually use a pipe bender for the whole run

Pith a gorean is rolling over in his grave.

Where is the series chart for fitings

Where does 1.41 come from?

I'm doing something in trade school and it's so hard. I can't measure it and put it together. Made me so stressed.

👍👍👍👍👍👍

Good English without eating words

Sit×run KitnA hai

Where can I find that chart?

10 3/10” right?

how did u get the 11.30''?

Distance X 1.4142 - diameter of pipe = length to cut the pipe

8 *1.4142 =11.3136 how can I change to a fraction?

perhaps you could explain the math as to how you came up with the 1.4142. good for a draftsman to know but i just eyeball it

But when do you use .707?

Eye ball the length of pipe .it never fails .

I always just stuck a 45 on point a and point b and then measured in between them. Idk why you would need all this math lol

I LOVE YOU! This is great for union plumbers that want to look smart over speed and efficiency ...But privatized plumbers like myself have a fast way! We mostly overlap and nip off extra (I save the extra for latter) time is money with non union plumbers and I would never use this tbh. Maybe you can show the speedy ways to do a 45 for the privatized plumbers? Time is money for both types of plumbers in opposite ways.
