he's asking where the sewer can vent. sewer's have to move air in order to work, so since there's sewer piping there they asked where the vent for that section of sewer was.

Ah okey! The pipes are connected with more stuff, and these have airvents :)

To drain correctly it needs a vent within a limited distance from the drain (4'-6' depending upon drain size and slope). I'm also concerned since I can't see a p-trap at the shower drain. It will be likely to smell.

But, really nice job on redoing the concrete and sloping the drain area well. And I love the new look.

XD the "p-trap", is that a water lock? That is in the drain, under that big lid. Which country are you from? Ive never seen a air vent so close to every drain ever in sweden. We may have 1 or 2 air-vents/backflow thingies in a whole house.
