Why Does My Kitchen Sink Drain Slowly? Understanding and Fixing the Issue

A slow-draining kitchen sink is a frustrating nuisance. Learn what causes these clogs and how to get your sink flowing freely again.

The Anatomy of a Slow Drain

Kitchen sinks see a lot of action, and over time, debris can build up inside the pipes, restricting water flow.

The Usual Suspects

• Grease and Fat: Pouring cooking grease down the drain is the number one cause of kitchen clogs. It solidifies in the pipes, creating a sticky trap for other debris.
• Food Scraps: Coffee grounds, eggshells, and expanding foods like pasta and rice can easily cause blockages, even if you have a garburator.
• Soap Scum: Over time, soap residue can accumulate and restrict pipe diameter.

Safe Unclogging Methods

Avoid harsh chemical drain cleaners, as they can damage your pipes. Try pouring boiling water down the drain, followed by a mixture of baking soda and vinegar. If the clog persists, a plunger or a plumber's snake is the next best step.
