Why Does My Kitchen Sink Smell?

In case your kitchen sink is emitting an unpleasant smell, there might be several reasons behind it. It is advisable to take prompt action to prevent the odor from intensifying. The longer you delay, the greater the likelihood of bacterial growth, which may attract insects or exacerbate pre-existing plumbing issues.

Generally, there are two primary reasons behind a malodorous sink: either there is decomposing food lodged in the drain or garbage disposal, or there is a gas leak around the drain trap or vent. If the odor resembles that of stale food, it may indicate the need to snake the drain. Alternatively, the garbage disposal might require cleaning or replacement.

If the odor resembles gas, there may be a need to replace the drain trap in the event of a leakage, or there might be a blockage in the drain vent. Unless you possess excellent plumbing skills, it is recommended to seek professional plumbing services to address any gas-related odors.

One other factor that individuals often disregard (only to realize it later and chuckle at themselves) concerns the trash bin. If you store the garbage in the cabinet beneath the kitchen sink, be sure to inspect the bin to ensure that the smell is not originating from outside the sink.

For minor problems related to food, follow these steps to eliminate the odor:

1. Put some ice cubes down the drain and run the garbage disposal to clean the blades.
2. Use a store-bought drain cleaner or make your own homemade cleaner with baking soda and vinegar, then flush with boiling water.
3. Place small orange or lemon rinds down the drain (one at a time) and run the garbage disposal to deodorize.

If this doesn’t solve the problem, you may need to call a plumber to inspect the drain and garbage disposal. Give MET Plumbing & Air Conditioning a call today at 281-603-9949.
