A homeowner called me about sewer gas smell at all 4 drains in a new 3 story house ( less than 1 yr old). I replaced 3 “surevent” thingies at each drain except the top floor near the” real” vent.
These wre obviously someones idea of a shortcut. Just because code allows tem doesn’t mean it is best or even functional.
What say you?

They work, that is why code allows them.
