The Drain's Secret Journey
Where does the water go after it goes down the drain?
You pull the plug and whoooosh — down it goes. Your bathwater spirals into the drain and vanishes. But water doesn't just disappear into nothingness. It's starting a pretty wild underground journey, and you can follow it if you know where to look.
First stop: the pipe under your house. All your drains — sink, shower, toilet — connect to one big pipe called the sewer line. It's like a highway for used water, sloping gently downhill so gravity pulls everything along. No pumps needed yet. Just tilt and flow.
