A vent is a pipe in a plumbing system that allows air to enter the drain system, maintaining atmospheric pressure and facilitating the free flow of wastewater. Vents prevent the siphoning of water from traps, ensuring that the water seal remains intact and blocking sewer gases from entering the living space. Proper venting is essential for maintaining efficient drainage, preventing clogs, and complying with plumbing codes. Regular inspection and maintenance of vent pipes help prevent blockages, ensure effective drainage, and maintain safe indoor air quality.
