In a conventional household, water from a kitchen or bathroom sink flows down a drain. This drain leads to a storage compartment that is periodically emptied.

Rotate the snake handle clockwise to break up the clog. Continue pushing and rotating the snake until the clog is cleared. Pull out the snake and run hot water to flush out any remaining debris.
