Which of the following terms best describes an obstruction caused by a closure in a piping system?

The term "Dead end" is often used to describe a situation in a piping system where there is a closure or termination point, which leads to an obstruction. This means that the flow cannot continue past that point. Understanding this term is essential in plumbing, as it refers to sections of pipe that do not connect to an outlet, resulting in a location where water or fluids can become stagnant, creating potential problems for drainage and flow within the system.

Other terms, while related to obstructions in plumbing, do not specifically capture the concept of a cessation of flow at a defined point in the piping system like "dead end." For instance, "blockage" and "clog" are typically used to refer to unintended obstructions caused by materials accumulating within the piping, limiting or halting flow. On the other hand, "stoppage" can refer to any interruption in flow, but it does not inherently communicate the idea of an ending point in the system's configuration like "dead end" does.
