Vent Stack
A Vent Stack is an essential part of a building's plumbing system that helps keep everything working properly. It's like a breathing tube for the plumbing - it lets air in and out so water can flow smoothly through pipes and drains. Without proper venting, drains might gurgle, drain slowly, or create unpleasant odors. Plumbers need to know how to install, repair, and maintain these systems following local building codes. You might also see it called a "plumbing vent," "soil stack," or "vent pipe" in job descriptions and resumes.
