A studor vent may or, may not be allowed under your local plumbing code.
I would check if the local code allow the usage of a studor or, AAV.
They are not the best way to vent and a poor replacement for a through the roof vent.

In your diagram the studor is improperly placed and needs to be changed. Check your local code.

Thanks for the heads-up. I bought a Studor kit at Lowes last night, and the installation instructions have it coming right off of the s-trap. In fact, the kit comes with its own s-trap and shows a picture of the studor vent in-line, right after the trap.

Where is it "supposed" to go?

By the way, this is not going to be a permanent installation. I plan on making the whole drain system removable, in case we ever move. I just need a sanitary, enclosed method of draining off my excess wine fluids.

S-traps are illegal under every code I know of.
The Studor has to extend above the flood rim of the sink check your local code for distances. The way it is lied into the lower drain also prevents a venting problem. Wet venting between floors is not permitted.

Pardon my terminology, I'm sure it's not an S-trap if they are illegal. The kit includes your standard, very legal trap, whichever letter of the alphabet that may be.

I'll be sure to place the studor above the flood line if I do use it. some PVC piping will easily extend the tube above the height of the sink.

As for the wet venting issue, I think there are other systems in the house which already do this. The house was built in the forties, was this allowed back then?

No wet venting between floors wasn't legal then either.
This old picture shows proper venting of every fixture...

Very cool and helpful for reference. Thanks!
