I am in the process of renovating my kitchen and removed a wall. I discovered a closed off drain and a vent that goes through the ceiling.
There does not appear to be anything else tied into the vent. It also appears to be an old laundry area. Maybe it’s not important but there is an active sink next to it. It has a separate drain and its own dedicated vent out the ceiling.
It will be blocking the walk way so it needs to be removed. Is it safe to cap off the entire pipe and cement over it? Anything else I should be cautious of before I proceed?
I have a licensed plumber standing by, just waiting for him to fit me into his schedule. I would love a second opinion.
