  7. Drain-waste-vent system - Wikipedia

    en.wikipedia.org/wiki/Drain-waste-vent_system

    A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.
