drain trap

Curved pipe section

A drain trap is the curved or U-shaped section of pipe beneath a sink, shower, or other fixture.

The bend holds standing water that blocks sewer gases from rising into living spaces.

Traps occasionally clog with debris and may need cleaning: The plumber cleared a hair clog from the drain trap.
