What is branch ventilating pipe?

A branch ventilating pipe is a component of a drainage system that allows for the escape of sewer gases and helps maintain proper airflow within the Plumbing system. Typically connected to a main vent stack, it serves individual branches or fixtures, ensuring that pressure is balanced and preventing siphoning of traps. This helps minimize odors and improves the overall efficiency of waste drainage. Proper installation and sizing are crucial for its effective function.
