How a P-Trap Works: Plumbing Diagram & Flow Explanation #297267 (License: Personal Use)

The image displays an isometric schematic of a standard P-trap, a U-shaped pipe section used under sinks and drains. Red arrows trace the path of wastewater entering from the fixture and exiting downward, while blue arrows indicate air circulation that preserves the water seal in the trap’s bend. This seal prevents sewer gases from entering living spaces.
