Usually a screw in plug somewhere in the drain that lets you run a snake or auger in the drain without having to pull up a stool or other fixture. There is usually one in the main line between the last fixture and the sewer line in the street. There can be smaller ones anywhere in the drain system. Very often in the main sewer line in the basement 3 to 5 feet above the floor and in newer construction, it is outside the foundation, a 3 or 4 inch pipe just sticking out of the ground with a cap on it. This keeps the mess outside.
