Aggregate Venting in the Uniform Plumbing Code

[@nickw8275]

At minute 12:00 ; Why did you decide to upsize the toilet stack, Could you have chosen a different vent to upsize?, Does the UPC specify a process to decide which vent to upsize?, My study guide for my exam specifies a very confusing process to decide which vent to upsize and in what order to continue upsizing for the WA UPC test.
The problem is that if I upsize the wrong vent, then upsize the wrong relating drains to breath freely with the sewer, then I would get a bunch of answers incorrect on my test.
That said you were the only instructor bold enough to teach this in this crucial detail and for that I commend your good efforts and thank you.

I have a question. What happened to the lowest level ventilation? Is there no ventilation at the lowest level in your version? Thanks for the answer.

The lowest level is all vented upstream of the pumping station (pumps are not factored into the venting calculation for the aggregate building sewer.) it has its own vent pipe that’s going through the roof

Why did you make it so hard and with all that math why don't you just figure out your fixture units and size it from there it's that simple.
