PS One thing to consider if there are currently no fixtures in the basement is whether that arrangement was done to prevent spills from sewage backup. So if the new san-tee/wye connection would be below the next downstream manhole, then you'd need a backflow preventer as well. And it might be worth considering tying in higher up, on the floor above, to avoid that.
