I believe this is the vent to my plumbing but I’ve never seen a cap like this. Any ideas?

    Sewer cleanout probably. Never seen a cap like this before though, looks kinda flimsy. Maybe get a piece of plywood and cutout/drill for holes that align with the nubs and turn the plywood so you can put force on all four nubs?

      These have a spring loaded flap in the center that lets out sewage if there’s a blockage downstream. Lets it out in the yard instead of your house.

      As for opening, I use channel locks opened up all the way wide on two of the adjacent lugs and turn left.
