When we built our house I did all the plumbing. I have the toilets and kitchen sink set up on the septic and the grey water is discharged elsewhere (legal here). Studor/AAV are allowed almost everywhere although some places are very restrictive on there use while others could care less. Here I don't have any code to follow so I did what I thought was best after lots of studying. My toilets are ran through a vent through the roof thats 3". Kitchen sink is on a bar between kit and living room so it has an AAV. Everything else is on an AAV. Each bathroom has one even though most are rated up to 12 fixtures. No problems here and all works great.
