A U-bend is a section of a waste pipe shaped like the letter ‘U’, commonly used in traps under sinks, bathtubs, and other fixtures. It retains water in the bend, creating a barrier that prevents sewer gases from entering the living space. U-bends are typically found in P-traps or S-traps, depending on the fixture and installation requirements. Proper installation and maintenance of U-bends, including regular cleaning to prevent clogs, ensure effective drainage and odor control. They are typically made from materials like PVC, ABS, or metal, depending on the application.
