👉 A downspout is a type of drain system that collects rainwater from a roof or other surface and directs it away from the house. It is typically installed at the bottom of a roof, near the foundation, to catch rainwater and redirect it into a drainage system underground. Downspouts can also be used as a way to capture stormwater runoff and prevent it from seeping into nearby buildings. They are often positioned at a slight angle to avoid blocking off pathways or other potential hazards.
