5 Reasons Your Kitchen Sink Smells Bad

Kitchen Sink

It is believed that the kitchen has more bacteria and germs compared to the bathrooms. Kitchens do get messy and gross quickly, and that is why we must clean our kitchen every day. 

But, sometimes, despite cleaning the kitchen with all the possible disinfectants and kitchen cleaning chemicals, we cannot get rid of that strange smell. That is an indication of a problem with the sink. Even if the kitchen is squeaky clean, the kitchen will smell bad if there is an unsolved problem with the sink.

Here are some reasons why your kitchen sink might smell bad.

1. Unused Drain

If the drain pipes of your kitchen sink haven’t been used in a while, say if you are off on a weekend trip or a vacation, then it can smell. There’s a trap inside of every drain line which blocks or ‘traps’ the sewer smells from entering your kitchen through the sink.

When the sink is not being used, the water from the trap evaporates, which allows easy access to the nasty sewage smell in our homes. You can easily solve this problem by running hot water down the drain.

2. Greasy Drain

We all are guilty of dumping grease (and oil) into the drains, and this is the major cause of a smelly sink. The grease and oil coagulate in the drainage pipe and decompose gradually decompose. This causes that rotten smell, which makes its way into your kitchen. That is why you must never pour grease down the drain; apart from making the kitchen smell bad, it can cause pipe blockage too.

However, you can eliminate this problem by pouring a solution of baking soda and vinegar in equal parts in the kitchen drain, then finish it by pouring hot boiling water.

3. Dirty Garbage Disposal

Garbage disposal needs sufficient running water for it to be clean and free from food debris. But sometimes, food pieces get stuck in the impellers of the smallest garbage disposal, resulting in a rancid odor because the food rots away.

Dirty garbage disposal depends on several factors, such as:

  • Not running enough cold water each time after use
  • Garbage disposal needing replacement, or 
  • Dumping a lot of food at once

This problem can be avoided by dumping ice cubes and salt in the disposal and then running cold water; this clears away any food debris stuck onto the impellers. You can even drop lemon or orange peels in the disposal to get rid of the smell.

4. Clogged Plumbing Vent

The plumbing vent allows fresh air inside your drain, which ensures water runs smoothly through the drain pipes. If the vent is clogged, then sewer gas can move into your kitchen and house, no matter how good your kitchen design is.

A clogged vent can be cleaned if the blockage is easily detected and can be removed by yourself, or else you must call a professional to deal with a clogged plumbing vent. So, if your vent is clogged, you need to stay mindful and follow these instructions.

5. Food Debris In The Pipes

Shredding and eliminating our food waste in the garbage disposal does not guarantee clean pipes; it is possible for food to get stuck and even block the drain pipes.

Greasy food hardens on the sides of the drainage pipes, and gradually mould forms which causes a rotten smell in the kitchen. Also, other food particles may also start accumulating on the greasy moulded food waste resulting in narrow drain pipes, which eventually cause a drain blockage.

You can avoid food junk from building up in the drain pipes by pouring down the drain a solution of hot water and liquid detergent or vinegar and baking powder solution, every two weeks to avoid blocking the drain and having to call a professional.

These were five reasons for our kitchen to smell like sewage and the solutions on how to avoid and get rid of them.
