What Causes Smelly Drains?

Smelly drains are common issues in most houses and the nasty smell that emanates from the drains is often annoying and embarrassing. Many factors cause smelly drains and let us see some of them.


Food is one of the main reasons that cause clogging in your drain. Scraps of foods don’t get washed down the drain and stick to the pipeline, decompose over time, and cause nasty odours.

Sewer Gases

If you smell sewage odor from your drain, it means that the P-trap (the curved structure under the sink) is empty. It happens when you don’t use your sinks often. There is a goose-necked section of the P-trap that collects some water which helps to block the sewer gas from wafting up through the drain.

When you don’t use the sink, the water in the P-trap evaporates and the smell comes up. Make sure that you are using each of your bathroom fixtures regularly to prevent P-trap from drying. Or simply run plenty of water

Missing Vents

Vent pipes are essential to let the fresh air in and allow the nasty smell to escape. Usually, these vents are fixed away from windows and other vents. If you are missing any vents then talk to your plumber to get one installed.

How to Fix?

Before you start cleaning make sure that you clear food, hair, or soap scum to prevent them from getting washed down.

Baking soda, hot water, and vinegar are useful ingredients that help cleaning your clogged drain and destroy nasty smells.

Pour boiling water into your smelly drain and allow it to loosen up the petrified residues. Wait for some five minutes and flush your drain again that will clear away any remaining grease. You can also make it a habit to flush the drain with hot water at the end of each day. This will help any substances from building up inside the drain.

You can also add baking soda that works best as a cleaning agent. Sprinkle a teaspoon of baking soda in the drain and let it clear up the particles and bacteria build-ups. After an hour or two pour boiling water to rinse the drain.

If you are using vinegar, then boil few cups of it and pour it into the smelly drain. Allow it to sit for an hour then rinse it with boiling water.

Seek the help of a plumber if the problem persists.
