This video is an exercise in sizing gas systems. I explain both the longest length and the branch length methods of sizing. Please watch and let me know if there any questions. This is based on the information provided from the Uniform Plumbing Code 2018 Edition.

Exactly what I was looking for. I will be using CSST and propane for my system but I'm sure the metrics still apply as the correct charts are used. Thank you!

@BGsPlumbingClass Жыл бұрын

Absolutely! If you use the correct chart, the sizing is going to work out.

Hello. Great class. I have a question. How did you get the 80 feet distance to solve the small extension of the main pipe that has a 1" right before the FAU and the Dryer branches?

@BGsPlumbingClass Жыл бұрын

Short answer is if you add up the distance from the meter to the dryer it equals 73. Since there is no 73' in the table, the next max available is 80'. Keep in mind this applies in the branch length method only.

Great video… I will take my test in August and this helps me a lot. Can you post another video of drainage and venting sizing which is the one I’m having most problem to fully understand?

There is a sizing video in here somewhere. If you can, check it out. Let me know at gorhambm@outlook.com if you need more assistance.

Hi man, how do we know which table to use in Table 1215? How do we figure out the pressure drop for our system?

@fusser1710 Жыл бұрын

Second question. Is the whole main line 2" using the branch method? If yes, did you get this by using the 125 distance and by using the total of all of the CFH from all the appliances?

@BGsPlumbingClass Жыл бұрын

Yep. And yep. That's exactly right.

@vickyr8360 2 жыл бұрын

I have a situation, my new firepit requires 240k and it is 60’ away from meter. The current pipe line is as follows-from gas meter 1” pipe size for 50’ distance and then branch out for 1/2” size for next 10’ distance to fire pit.Does this current pipe system would be good enough for 240k btu firepit?

@BGsPlumbingClass 2 жыл бұрын

What else is on the line? Do you think you could do a linear sketch of the system and email it to me at gorhambm@outlook.com so that I could analyze it further? We'll see what we can do.

@marisolvaldez9005 Жыл бұрын

I have my C36 exam tomorrow and I really like your videos. however, the main with the 50 ft length towards the bottom is 340 CFH. 145 +195= 340

Apologies for the late response. If you would like to get a hold of me, email me at gorhambm@outlook.com and we can discuss what questions you may have. I am now a plumbing instructor full time so I'd be happy to help.

How do you start with just the branch method?

@BGsPlumbingClass 7 ай бұрын

The branch method is just like the longest length method, except the branches that are separate from any line having the furthest outlet on it need be sized as it's own. So, any section of pipe that is involved in feeding fuel to the furthest outlet is sized based on longest length. I hope this explains it a bit. Rewatch the video and you'll see what I mean. Any questions, feel free to ask.

@jmac213stuff 3 жыл бұрын

by all means, have walk-though exams are the best. I have previously used the longest length method only, because I was told that the branch method, you had to be an engineer.

@BGsPlumbingClass 3 жыл бұрын

The branch length is more accurate, whereas the longest length increases branch sizes in just a few areas most times- which isn't necessarily a bad thing. The longest length ensures demand will be met.
