Downspouts are vertical pipes that direct rainwater from a building's gutters down to the ground or a drainage system. They help prevent water from pooling around the foundation, which can lead to structural damage and erosion. Typically made of materials like aluminum, vinyl, or steel, downspouts come in various sizes and styles to fit different architectural designs. Proper installation and maintenance of downspouts are essential for effective water management. They should be positioned to ensure water flows away from the building, often ending in a splash block or drainage system. Regular cleaning helps prevent clogs from debris, ensuring they function efficiently during rainstorms.
