What type of pipe is used specifically for venting waste gases from plumbing systems?

Venting systems in plumbing are essential for allowing waste gases to escape safely and for maintaining proper pressure within the plumbing system. The type of pipe specifically designed for venting waste gases is known as a venting pipe. These pipes play a crucial role in preventing the buildup of harmful gases and odors within buildings by allowing fresh air to enter the system and enabling the harmful gases to exit.

Venting pipes are typically connected to the drainage system and are strategically placed to ensure that all fixtures within the plumbing network function correctly. They help to maintain the necessary atmospheric pressure, which prevents siphoning of water in traps and maintains the water seal, preventing sewer gases from entering the building.
