Given how often you use your kitchen sink, it is one of the most susceptible drains in your house to clogs. If yours gets clogged and you’d like to try to fix the problem before giving us a call, try following these instructions for how to unclog a kitchen sink on your own.

Why does a kitchen sink get clogged?

Like all the drains in your home, your kitchen sink has what’s known as a “trap” in the piping below. This trap is often a “U” shaped pipe that is designed to catch anything that was mistakenly dropped down the drain. It also blocks harmful sewer gasses from travelling up through your sink. The trap is often the site of kitchen sink clogs because food and other objects can build up in the trap, especially if you put things like grease down the sink that don’t drain well.
