What is the term for a pipe that conveys storm water from the roof to a storm or combined building drain?

The term that specifically refers to a pipe that conveys storm water from the roof to a storm or combined building drain is known as a Storm Conductor. This terminology accurately captures the function of directing rainwater or stormwater down to the drainage system, playing a vital role in managing water runoff during rainfall.

Understanding this function is crucial for plumbing and drainage design, as appropriate terminology ensures that professionals can effectively communicate the duties of different components within the plumbing system. While other terms, such as Storm Drain, Rainwater Chute, and Water Conduit, may relate to aspects of stormwater management, they do not specifically describe the function of transporting water directly from the roof to the drainage system as accurately as Storm Conductor.
