Smelly plumbing mystery - what is this? (extra pics in comments) (lemmy.world)

Our laundry room sink has this bizarre attachment to to the back of the drain line clean out. It would almost seem like it was or is supposed to be a vent. Recently it’s started to give off a foul sewer smell when our washing machine rinses.

Can I safely plug it? Maybe remove it if I can manage to pry it off? When I asked our plumber what it was, he just smirked and said it was a “crazy thing.”

I’m open to the ghetto solution for the time being while I cap it. I replied to another comment with a pic of the main vent stack so it looks like I’ll be able to cap it. Just have to figure out the best way to do that.

They make what is called a studor vent for this situation. Not sure if there are code restrictions for different areas. If allowed you can put them under sinks etc to get better venting of sewer lines.

Huh! I’d never seen one before. Really simple fix. Thanks for the suggestion!
