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

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.

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!

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

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.

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

[zummliller]

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

[billybike]

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

[catalinbazavan]

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!

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.

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

[notreal]

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

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!

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👍

[T.E.P.]

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

[astroboymamuyac]

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

[aaronsheflin]

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.

[CopperChief]

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.

[poyoloko]

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
