What are short lengths of pipe attached directly to a fixture called?

The term for short lengths of pipe that are directly attached to a fixture is "tailpieces." Tailpieces serve as a vital connection between plumbing fixtures, such as sinks or toilets, and the drain lines. They are typically used to extend the fixture’s outlet and provide a pathway for wastewater to flow into the drainage system.

Tailpieces are usually made from materials such as PVC or metal and vary in length depending on the installation needs. Their design ensures that the fixture has a proper seal and minimizes the chances of leaks. This feature is critical for maintaining the overall functionality and integrity of the plumbing system. Understanding these components is essential for effective plumbing installation and maintenance.
