I'm going through some articles to find my rough-in heights for a 36" tall kitchen sink and vanity. It seems like 16" off the floor will work for both.
But in the process I came across this article and I'm confused about why they ran their drain like they did.

Wouldn't it have been more normal to just use a san-tee to connect to the vent stack? Doesn't this risk creating a siphon? Are you allowed to have a vertical drain section before you vent?
