Can I cap this bow vent?

Question

I am removing a kitchen from a basement which had an island sink. I will be leaving only the sink along the wall which has its own vent. Can I just cut both legs of the bow vent and cap it flush with the concrete floor? I don't know where these lines tie in to the header but would it be safe to assume that nothing else would vent through this line? Thanks.

Answer 1

It's unlikely that anything upstream also vents through that line. It looks like modern pipe in a modern home, so we can presume that it met code.

Yes, you can cap them. There are no rules against pipe stubs that would prohibit doing so, to my knowledge.
