I was doing some other work in a house and this was the kitchen. Has anyone ever seen a vent like this?

Revented vent, disposal washes the strainer basket, and the clean out is the touch of a pro!

Air likes choices, air gets mad when it's forced to travel down one vent, one way, so plumbing systems always work better when you give the air multiple options on where to travel. Free market baby.

That's what I tell my wife but instead of opening the windows she tells me to go outside.

It does appear the fellow that piped this had his retirement fund invested in ABS manufacturing.
