wow , that was quick. still looking for the answer on this one. individually venting everything looks like such hard work. we just don't do it in the UK and it seems to cause no problems. like I said we did do it 100 years ago but now we don't. No disrespect to the USA your building is fantastic. I'm just curious

@aaron85077 I'd love for you to tape a video of a rough plumbing piping system completely installed and just before it's covered up. Load it to your channel and come back here and tell us about it. Then I'll add it as a Video Response. We'd LOVE to see how you have gotten away from vent pipes over there. My guess is oversized drain piping. Let me know as soon as you have the video loaded to your channel. Come back and post a new comment.

If you go to london on the train you pass by victorian buildings that have this funny venting.  You can see it very well because in England it's all on the outside of the buildings. But this practice has long since been disgarded because all you have to do is slope your waste lines correctly and there is no need for these time consuming ventlines!

@aaron85077 I hate to say this, but you're so wrong. Go to my AsktheBuilder website and read all my past columns on Plumbing Vent Lines. Read the story about my buddy Dave and his kitchen sink and washing machine.

We use anti-vac traps on all basins and baths in the uk, generally the 4" soil pipe is vented to atmosphere and all internal connections can be bossed into the stack on deep-seal traps with no problem at all. Never had any issue with using AAVS either and I'm talking about ones installed maybe ten yrs ago

@MrRichardDude We've run vents inside for over 100 years. Well, some places here in the US like New Orleans, have outside plumbing stacks. Perhaps the biggest reason I can think of is we have much colder weather here and the stacks would freeze solid.

wow do you guys actually still run that many vents?? its just not needed we used to have a similar system in new zealand mind you that was a long long time ago!!! really seem behind the time???

I always wondered what that pipe was for, thanks for the video

@AsktheBuilder Oh, I went to the Studor website. You know, the official one of the manufacturer that makes these mechanical valves. Here's one of the bullet points from their sales page about the valves:

Limited lifetime warranty for replacement of defective valves

Even they recognize that the valve WILL FAIL.

@2020starman Well, wait till your mechanical vents fail. And they will. It's just a matter of time. I dislike mechanical vents and only use them as a last resort.
