I had a blocked drain last week, and it was a real mess. The water just sat there in the sink, and it started smelling awful. I tried a plunger and some drain cleaner, but nothing worked. Finally, a plumber came and used a special auger tool to pull out a huge clump of grease and hair. The water went down instantly after that.
