Kitchen Drain Smell- Causes & Solutions

If you think that refrigerators and garbage cans are the only sources creating smell in your kitchen, you are wrong. The kitchen drains and sinks are also to be blamed! Fixing any problem with the kitchen drain as early as possible is advised as it might lead to a serious plumbing issue. Let us see why drains smell and how to fix them with drainage cleaning services.

When to Reach Out to Drainage Cleaning Services?

There are a few common causes of kitchen drain smells. It is best to seek help from drainage cleaning services in Chennai and resolve the issue when they occur.


Debris or food build-ups are the reason for blockages in drain pipes. Food waste gives away a bad odour, and as a preventive measure for blockage, one has to use running water for a few seconds and flush out the contents. The lowest point in the sink is curved and has a feature to clear the blockages. Cleaning the curved part of the sink once every week is a simple hack to get rid of blockages. But when these self-maintenance operations fail, it is advised to get help from drainage cleaning services.


Clogs are another major reason for creating an unpleasant smell in the kitchen. Clogged drains are made of organic matter and food substances, which, when left unattended, develop a bad odour. Methane is a by-product when organic waste gets decomposed, and so the sewer gas smells horrible with the accumulation of food particles. The bad smell in kitchen drains may be an early indicator of clog. When it becomes impossible to clear the clogs by DIY methods it is best to bring the problem to the attention of good drainage cleaning services.


Leakages are the main culprits when a kitchen drain smells terrible. Pipe connections in the sink are highly prone to leakages. Therefore, if you suspect any leaking, you can unscrew the pipe connection, remove the P-trap, and clear the accumulated food waste. When this type of cleaning process is made a habit, it becomes easy to prevent the bad odour and preserve the well-being of the home space. However, if you haven’t addressed a leakage before, contact professional drainage cleaning services to avoid damage costs.

P-traps are a significant part from which bad odour arises if there is a problem. The curvy portion of a draining pipe on the bottom of the sink has the P-trap, which resembles a ‘U’ or a ‘P’. It holds water at the lower part of the curve and seals the smell. But if the P-trap becomes dry without usage, it lets the smell creep into the house. Therefore, allowing running water into the sink continuously is the best way to rectify the problem. So, keep the seal in a working condition always. Problems in P-traps cannot be identified with a glance and require special equipment to resolve the issue. Call your nearest drainage cleaning services if you need help sorting out any kitchen drain smell.

Sewer Breaches

Any breach in the sewer line will affect the well-being of the entire place. It is a serious issue that can cause the most disgusting smell and must be addressed with drainage cleaning services.

Venting Pipe Blocks

When venting pipes get clogged with debris, they will become incapable of releasing gases away from the system and start sending them back into the system. This will lead to a bad odour which requires the help of good drainage cleaning services to get back to normal.
