In plumbing, a dead end refers specifically to a section of piping that does not provide a continuation or connection to the rest of the plumbing system. When considering the definition provided in the choices, a cap or plug on a branch from a soil or waste pipe is indeed a definitive example of a dead end. It is an intentional closure of the piping that prevents any further flow of water or waste, effectively rendering that section of the pipe inactive.

This situation is significant in plumbing because dead ends can lead to issues like stagnant water, which in turn can cause odors or even health hazards if not properly managed. They are crucial to note during system design and troubleshooting, as they impact how waste is efficiently moved through a plumbing network.

The other choices do not align with the definition of a dead end in plumbing contexts. A pipe that connects directly to the sewer does not represent a dead end but rather a functional connection. A broken pipe would not be categorized as a dead end, as it implies a failure in the system rather than an active design feature. Lastly, a vertical pipe segment, unless terminated, does not inherently constitute a dead end either. The definition is focused specifically on terminal closures in waste and soil plumbing systems, making the option referring to a
