Stinky Sink? Common Reasons Your Kitchen Sink Stinks

Blog

Most people spend a good amount of time over their kitchen sinks. Washing their hands, scrubbing pots and pans, and disposing of food debris in a garbage disposal are all common tasks. Because of this constant use, you may smell some odors coming from your sink and drain periodically. If you are smelling a foul odor constantly, there may be an underlying issue to address. Here are a few common reasons you are dealing with a stinky kitchen sink.

Food Residue

In many cases, the odor is stemming from a build-up of food debris and other residue inside your sink and drain. If you have a garbage disposal, the residue may have built up on the disposal blades. Fortunately, if the smell is caused by food, grease, and other debris in the sink and drain, there is an easy solution.

To get started, use a cleaning solution to scrub your sink and interior rim of the drain clean. If your sink is stainless steel, make sure to use a cleaner designed for this material to avoid scratching the finish. Then, bring a few pots of water to a boil on your stovetop. When boiling rapidly, carefully remove the pots and pour the water straight into your sink drain. The hot water will dislodge any stubborn residue in your sink and drain.

Cleaning your disposal blades is also necessary. After pouring the boiling water into your drain, peel a few lemons and place the peels into your drain. Turn the disposal on so the peels are cut up by the blades. The lemon peels will help scrub the blades clean while freshening up the inside of your drain.

P-Trap Issue

The p-trap is an important part of your sink even though most people do not even realize it is there. It is located under your sink, so most likely you can find it in the cabinet. It is the u-shaped pipe that extends from the bottom of your sink and then up into the wall.

The purpose of the p-trap is to act like a seal, preventing sewer gas from moving up into your sink drain and into your home. Unfortunately, if the p-trap is clogged with food residue, grease, or other debris, the p-trap will lack the proper ventilation needed to keep sewer gas out of the home.  

Known as a dry p-trap, this lack of ventilation can cause a rotten-egg-like smell in your sink drain that may affect your entire home. Other issues can cause a dry p-trap. If you have an underlying leak or a broken seal, the trap will become too dry to function properly.

A kitchen plumber can inspect your sink drain and p-trap to determine why it is dry and not functioning properly.
