In the intricate network of a residential plumbing system, the plumbing stack stands as a vital component, often unseen but essential for the smooth functioning of the entire system. Understanding what a plumbing stack is and its role in your home’s plumbing can help you identify issues early and ensure efficient operation.
A plumbing stack, also known as a plumbing vent or drain stack, is a vertical pipe that extends from the main drainage system of a building to the roof. It serves as a conduit for wastewater and sewage to flow out of the building and into the municipal sewer system or septic tank.
