Plumbing drainage venting

Plumbing drainage venting is a way for water to get out of your house without flooding it. It lets water out of your pipes and sinks, and it also lets air in, so that the water flows out of your house smoothly. This is really important because otherwise, your house would flood and things would get really wet and messy. Think of it like a straw- the air inside the straw helps push the drink out, and that's what the vents do too. They're like little straws in your house, pushing the water out, and letting air in, so that your house stays dry.
