Good explanation. This is probably why a plumber suggested I would need a separate 1" gas line from the meter if I wanted to replace my tank water heater with a tankless water heater.

I’m 7 years in as a plumber and this video helped me way more than the Trac pipe class. Thank you!!

Jumping back into plumbing/gas fitting after a 9 year hiatus and hoping to challenge my Gas B exam. This breakdown is an incredibly good refresher man. Much appreciated.

Good stuff. Nice, clear easy to understand presentation. You should do this for a living.

Another very interesting informative pipe sizing I like it. I’m originally from Missoula noticed once again you’re from Montana. Currently a plumber apprentice in Minnesota planning on getting my journeyman’s license in a few months. Studying up on pipe sizing diagrams. Thanks again for another great pipe sizing video. 🙂

Cool, when doing longest length I’ve always sized the main first and then went back and sized the branches but this is a good way to do it

Hi
Thank you for the video, can you give example of sizing by using LPG and extracting sizing data from NFPA 58
