Trap

A trap is a curved section of a drain line, typically shaped like a U, S, or J, designed to retain a small amount of water after each use. This water acts as a barrier, preventing sewer gases from entering the living space through the drain. Traps are found under sinks, tubs, showers, and other fixtures, and they are essential for maintaining hygiene and safety in plumbing systems. They can be made from materials like PVC, brass, or chrome, depending on the fixture and application. Regular cleaning of traps is necessary to prevent clogs and maintain effective drainage.
