What if there is black stuff is coming out of the drain?

Answer

It's possible that your whole drainage system is backing up, and that it is raw sewerage that you're seeing. You should be able to tell from the smell. Another sign of this is when multiple drains and toilets in the building are no longer draining or flushing properly. This will be a job for a professional plumber, if so, as there are serious health hazards as well as plumbing issues involved.
