I think I just found the answer to my question 1). 5) At least one soil-or-waste stack or vertical soil-or-waste pipe must extend into a stack vent or into a vent pipe that is terminated in open air. That soil-or-waste stack or vertical soil-or-waste pipe must be as far as possible from the...

Just referenced the National Plumbing Code (Canada). Multi-story wet venting is allowed provided (in the case of 2"): h) where a wet vent extends through more than one storey, the total discharge from any one storey above the first storey does not exceed 4 fixture units, so I should be good...

ok i think i get it. it is virtually impossible that water draining down a 2" pipe from a draining kitchen sink would siphon a lower trap. but anyhow the code is the code. i guess the proper solution is to run a 1 1/2 ABS parallel as a vent stack which would be so much work. i would have to...

Hi, First time posting. I am renovating an older building and want to correct some plumbing in the process. 1. The 3" stack vent was reduced to 2" above the last fixture at "B" then upsized back to 3" at "C" before it exits the roof. I assume I need to replace that section of 2" with 3" to...
