What is the purpose of a vent pipe in a plumbing system?

The function of a vent pipe in a plumbing system is primarily to release sewer gases. This is crucial for maintaining a safe and effective plumbing environment, as it allows harmful gases produced in the sewer system to escape into the atmosphere instead of building up within a home or building.

Moreover, vent pipes help to equalize pressure in the plumbing system, which is essential for preventing vacuum conditions that could impede the flow of wastewater. By providing a pathway for air to enter the system, vent pipes ensure that drains can operate efficiently, facilitating the smooth passage of water and waste. Additionally, they prevent the possibility of harmful gases entering living spaces, which can be a health hazard. In this context, the role of a vent pipe is integral to the overall functionality and safety of plumbing infrastructure.
