What is defined as any vertical line of soil, waste, or vent piping?

The term defined as any vertical line of soil, waste, or vent piping is a stack. In plumbing, a stack is crucial because it refers to the vertical arrangement of pipes that facilitate the flow of waste and venting systems in buildings. This configuration is vital for proper drainage and ventilation, ensuring that gases released during the waste movement do not accumulate and pose a health risk. Stacks also help maintain the correct pressure within the plumbing system, preventing siphoning and ensuring consistent flow.

In the context of the other choices, a column typically refers to a structural element rather than a plumbing component. A pedestal is often a base support for fixtures and is not used to describe piping. A pipe chase is a space or duct used for housing pipes but does not specifically refer to the vertical line of soil, waste, or vent piping itself. Thus, the correct definition aligns specifically with the role and function of a stack in plumbing installations.
