A sweep is a drain elbow fitting with a long radius, allowing for a smoother change in direction compared to standard 90-degree elbows. It is commonly used in drainage systems to facilitate better flow and reduce the risk of clogs, as the gradual curve minimizes turbulence and debris accumulation. Sweeps are typically made from materials like PVC, cast iron, or ABS, depending on the type of drainage system. Proper installation of sweeps helps maintain efficient flow, prevent blockages, and ensure compliance with plumbing codes.
