Stinky Drains Explained: Why Do Drains Smell and What You Can Do About It

Table of Contents

We’ve all experienced it at some point – that unpleasant odour coming from our drains. It’s not exactly the most pleasant thing to deal with, but don’t fret, my friend! We’re here to shed some light on why drains have a bad smell and what you can do to tackle this stinky situation.

Why do drains smell?

Well, the culprit behind that foul odour is often a build-up of organic matter in your pipes. Over time, things like food scraps, grease, and hair can accumulate in your drains, creating the perfect environment for bacteria to thrive. And let’s face it, those bacteria can produce some seriously nasty smells!

But it’s not just organic matter that can cause drains to stink. Blockages in your pipes can also trap water, which in turn leads to stagnant pools of water. And you guessed it, stagnant water is a breeding ground for bacteria and an invitation for that unpleasant smell to make its way into your home or business.

What does a bad smell from your drains mean? Well, it could be a sign of a more serious issue. If you’re constantly battling with that stench, it could indicate a deeper problem such as a blocked or damaged pipe, or even a sewer line issue. Ignoring the smell could potentially lead to more significant and costly problems down the line, so it’s essential to address it sooner rather than later.

What causes the bad drain smell?

Now, let’s talk about what these smells could potentially mean. If the odour is reminiscent of rotten eggs, it’s likely that you have a problem with your sewage system. This smell is often caused by a buildup of hydrogen sulfide gas, which can be a result of a blocked sewer pipe or a problem with your septic tank. Rotting food is also a culprit. On the other hand, if the smell is more moldy or musty, it could indicate the presence of mold or improperly draining water.

Why do sewer smells come up through my drain?

The most common culprit behind this stinky situation is a dried-out or blocked P-trap. You might be wondering, what on Earth is a P-trap? Well, it’s that curved pipe under your sink that’s designed to hold water and prevent sewer gases from wafting back up into your home. If the water in the P-trap evaporates due to infrequent use or a slow drain, those nasty smells can make their way into your living space.

Another potential cause of sewer smells in your home is a blocked or damaged sewer line. Over time, debris, grease, and other gunk can accumulate in your pipes, leading to clogs or even cracks. This allows sewer gases to escape and invade your home through the drains. Yuck!

Now, let’s talk about what these problems could mean. If you’re experiencing occasional sewer smells, it’s likely that your P-trap just needs a good dose of water to fill it up again. Simply run the tap for a few minutes or pour water down the drain to replenish the water in the P-trap and create a barrier against the smells.

However, if the smells persist or are accompanied by other issues such as slow draining or gurgling noises, it’s time to consider a more serious problem. A blocked or damaged sewer line can result in more significant drainage issues and potentially costly repairs. It’s best to call in professionals to assess the situation and provide the necessary repairs or maintenance.

Is there anything I can do to prevent my drain from smelling?

Prevention is Key:

1. Regular cleaning: Make it a habit to clean your drains regularly. Hot water and washing up liquid is often all you need, and a good bleaching last thing before going to bed at night.

2. Mesh drain covers: Installing mesh drain covers can be a game-changer. These nifty little devices act as a barrier to debris making its way into your drainage system both inside and outside your home.

3. Avoid pouring harmful substances down the drain: Be mindful of what you pour down your drains. Avoid pouring grease, oil, coffee grounds, and other substances that can solidify and cause blockages.

4. Regular maintenance: Schedule regular drain maintenance with a professional drainage service. They can inspect your pipes, clean them thoroughly, and identify any potential issues before they become major problems.

5. Address issues promptly: If you notice persistent drain smells, slow draining, or any other drainage issues, take DIY action or call in professional help.

How can I reduce the smell coming from my drain?

1. Use Natural Deodourisers:

Mother Nature has gifted us with several natural deodourisers that can work wonders in reducing drain odours. Consider pouring a cup of bicarb of soda down your drain, followed by a mixture of hot water and vinegar. This concoction will not only help eliminate stenches but also tackle any grease or grime buildup.

3. Try Enzyme Cleaners:

If natural remedies don’t quite do the trick, you may want to consider using enzyme cleaners. These cleaners contain beneficial bacteria that break down organic matter and eliminate odours. Follow the instructions on the product for the best results.

4. Use a Drain Plug:

Sometimes, drain smells can be more persistent and require a stronger solution. Using a drain plug can help create a seal and prevent odours from escaping. Simply plug the drain when it’s not in use, especially overnight, and remove it when needed.

5. Seek Professional Help:

If you’ve tried all the DIY methods and the smells persist, it’s time to call in the professionals. A reputable drainage service can thoroughly inspect your drains, identify the root cause of the problem, and provide effective solutions.
