Calculating ABS and PVC Cut Pieces

[@dacrib5350]

Great video, there should be more like this. As someone who has worked with contractors that diagram like this for a job, and others who just work as they go, it's so much more preferable to work like this. You can hand a drawing with parts and cut list to your guys and take off for the day and come back and have them advanced to a certain stage instead of hoping they know the proper way to route a line and instead they end up overusing fittings or messing up. Yes it takes time and some brain power but it's so much more preferable for anyone working with or around you.

I agree 100% It is so important to be able to write a simple isometric, a skill that is lacking in most of today's plumbers. I am actually planning on doing a lecture soon on doing design drawings.

[@officialmatthewazua]

@@BGsPlumbingClass Any plans on how the lecture is coming along BG? Excellent material on your channel. Super thankful I found your page!

[@BGsPlumbingClass]

@@officialmatthewazua I will try to get on it this weekend. I have been meaning to provide more instructional videos for quite awhile.

[@officialmatthewazua]

@@BGsPlumbingClass I appreciate both of your replies! TYSM for the info & knowledge! I will be looking forward to them =)

[@BGsPlumbingClass]

As you can see, I didn't do it yet. I will. Been busy setting up a full time training area here.

[@officialmatthewazua]

Appreciate plumber here, SO grateful & thankful I found this video. Been trying so hard to find this formula or find this knowledge! Testing for my journeyman by EOY. Would this formula work for calculating rough-in measurements as well? Appreciate your videos!

[@BGsPlumbingClass]

Quick answer is yes. Longer answer would be, reading plans for rough in takes more of a working knowledge in plan reading. I did do a video on plans and reading them, but it is not as good as it could be (was done at the beginning of these, when covid first hit).

I just took the test in wa state and failed the waste sizing is there any where to get drainage drawings for residential waste and vents the study guides drawings were way less complicated than the actual test drawings for the waste I have been using your videos to help prepare and they helped tremendously seeing how I passed bothe the code section and the water sizing thanks for making such informative videos Justin

email me at [e-mail] and we will see what we can do.

[@baba-sm1fm]

Great information! Could you post the exact name of the catalog you are referring to, I am having trouble finding it on the web site. Thanks a lot!

[@BGsPlumbingClass]

I guess I should've done that. Here is the link to the PDF Catalog used in this video. www.charlottepipe.com/Documents/DimensionalCatalogs/Cast_Iron_Pipe_Fittings_Eng.pdf

@@baba-sm1fm No worries!

I cannot find a 3x3x2 combo in the Charlotte pipe catalogue.

[@BGsPlumbingClass]

Try page 50, I believe it's in there. The catalog I used in the video was updated just recently- I believe a couple months ago.

[@realdeal8078]

@@BGsPlumbingClass Isn't the fitting allowance 5 1/2 for both the 3" and 2 1/4 for 2"

[@BGsPlumbingClass]

@@realdeal8078 If you are referring to the Combo, the fitting take off for the 2" branch will be the "A" dimension which is 5 11/16"- or 5 5/8" if you want to round it- and the fitting make up for the 3" drain outlet will be the "C" dimension which is 5 1/8". Both of these dimensions work for ABS and PVC.

[@realdeal8078]

This a good video. Can you find all the fitting allowances in the Charlotte catalogue on every ABS Fitting that's out there? Also how are you so good at doing math in your head? It takes me a while to do it.

[@BGsPlumbingClass]

All the fitting allowances are in the Charlotte catalog- at least for the fittings they offer. That is for both ABS and PVC, so it's a good link to keep handy! I like to use my brother as an example of math because I have always liked it- wanted to be a math teacher for a while because I was good at it. He struggled throughout High School with math. But once he got into finished carpentry building bent rail staircases, he had to continuously figure measurements. Now he can do it in his sleep. So in short, repetition of the process makes it easier. You got it, half the battle is wanting to do it and you're there!

[@realdeal8078]

hey do you know of anyone online Plumbing tutors that can teach me how to calculate offsets or Fitting allowances.? I am having a challenging time.

[@BGsPlumbingClass]

What would you like to know more about? Cast iron, copper, threaded pipe? I have been meaning to do a video on fitting make up and calculating offsets. Let me know what specific challenges you are experiencing and I can help hopefully.

[@realdeal8078]

@@BGsPlumbingClass I would have to email you a copy of a worksheet

No problem! Thank you for watching! Hope it helps!

Do a rolling offset

[@BGsPlumbingClass]

I'll see what I can do. When is your practical?

[@ErikSArana]

I thought it was a planet!!! LoL 😅

[@BGsPlumbingClass]

Right?!

[@Dustin_the_wind]

When you have to cut into one of these full of saturation with a angle grinder, don't forget your safety glasses and don't open your mouth; or better yet stand out of the way of the spray. I wonder why Shay, didn't stand out of the spray?? He had the space.. huh. His face was covered. I guess when you're doubled down on a bad day, logic does get lost; come to think of it, I can recall my own questionable logic.. Work the job, don't let the job work you.

[@Dustin_the_wind]

I just thought of this, and I like it. Work steady, and don't try to rocket to the moon by lunch; you'll be thumbing it for the rest of the day. At least in my findings; just wear myself out, and make mistakes. "I've made a huge mistake.." Hello darkness my old friend, I've come to talk with you again..

[@BGsPlumbingClass]

Agreed!

[@Dustin_the_wind]

Thanks a bunch, Ben. Really wish I would have truly invested in the science of measurement when I was starting; you know its the smart thing to do, but you don't do it... AARRRRGGGGG!!

[@Dustin_the_wind]

But hey, at least one gets all that experience, getting the numbers the hard way..

[@Dustin_the_wind]

And scars*

[@BGsPlumbingClass]

I get so much push back from individuals that think it's better to just throw up a tape measure. What if all you have is a couple points? Plus, if you have the exact measurements at your immediate disposal, it just makes more sense to me to be perfect when given the opportunity. I think Vince Lombardi said "Strive for perfection, accept excellence" or something like that.

[@Dustin_the_wind]

And then fussing with makeup, long pieces, tight spaces above duct work in a joist bay at the rim of a house; the numerous environments that pop up, that aren't a rigid bump number right in your face. I definitely have some frustrated memories, of seeing how much easier, and time saving, it would have been to measure center to center on any type of pipe, and familiarize myself to the dimensions of the fittings I used day in and day out.

[@Dustin_the_wind]

If you push plumbing to its capability, it truly is amazing how much you can make the job go easier, with a center to center measurement. One reason why I make my layout marks so large, so they're still there for all to see after I drill the hole, and me to measure with. Save a bunch of sketchy ladder ballet, or recessed number acquisition frustration.
