How To Get Rid Of Smelly Drains?


How To Get Rid Of Smelly Drains?

Everyone wants to live in a clean, neat home that smells fresh as well. It's therefore extremely upsetting when you begin getting odd smells from your house. 

If there is an odour from your bathroom drain, kitchen sink or a bad smell that hangs around after you have taken out the garbage: you have a problem. 

Unfortunately, most people don’t pay much attention to their drains until it stinks up the entire house. Here, we help you learn where stinky drains come from, how to prevent them and what to do when you have one on your hands. 

What Makes A Drain Smelly?

There are several reasons why your otherwise unproblematic drain can turn funky and how to resolve the issue.

Bacteria Buildup

Over time, your drains pass a lot through them. This includes grease, food, hair, toothpaste, soap, dirt, name it. All this gunk can cause debris to accumulate and build up over time, emitting a foul smell. 

Even when these items do not form clogs in the drainage system, they create an excellent environment for bacteria to grow. Unfortunately, bacteria can also release odours into your home. 

Remedy: ensure to clean the drain's opening with soapy water and disinfectant. Also, always be sure to remove any solid food particles from the sink so they do not linger at the mouth of the drain or enter the pipes. 

Another effective tip is to pour hot water down the drain. This should help loosen grease and debris. Finally, you can run a baking soda and vinegar solution down your drain to freshen it. 


A perfectly working drainage system is open and wide enough to allow things to pass through them seamlessly. This directs dirt and other compounds from the house through the drainage and into the sewer system. In addition, a drain that works and flows well is unlikely to smell. 

However, when there are blockages along the pipes, food, dirt, grease get stuck in the drainage. Some of this, for example, food items, will begin to rot. Think about eggs, fish and vegetable particles rotting in a wet, enclosed space, and you start to get the picture. 

Remedy: whenever you suspect you might have a simple blockage problem, DIY unblocking tips can quickly resolve the issue. 

An easy resolution is straightening a clothing hanger and passing it through the pipe. 

This should push anything blocking the inside of the pipe. If the problem lingers, contact your local plumber. They can use industrial products to unblock and clean your drain safely. 


Mould is bad news in any part of a house. Not only can it cause respiratory issues in the occupants of a home, but mould can also interfere with your drainage causing awful smells. 

Mould loves warm, moist areas, and can grow and spread even from a seemingly small leak in the piping under your sink. With time, mould and mildew begin to emit puffs of musty, unpleasant smells that can infiltrate an entire room in your home. 

These are harmful to inhale and can cause headaches, dizziness and breathing problems. 

Remedy: the solution for this is in two parts. The first is to ensure a plumber comes in to identify and fix the leak. If you bypass this step, the problem will keep recurring. 

Once this is sorted out, you can embark on eliminating the mould. One way to do this is by scrubbing the area with mould, then spraying it down with full-strength white distilled vinegar. This should help kill the mould and its spores. 

Another solution is to use a 3% concentrated Hydrogen Peroxide spray on the affected area. A borax and baking soda solution is effective for mould elimination as well. 

You might have to repeat these treatments severally to ensure you have removed all the spores and to keep the mould from growing back. 

Tree Roots

Because tree roots love moisture, it's only natural that they are attracted to warm, wet drainage pipes. Unfortunately, while this is great for tree health, it's disastrous for your home. 

For one, tree roots block drainage pipes. One way to tell you have a problem is gurgling noises when flushing the toilet or using a tap. Unfortunately, this can send flushed material back up, causing a horrible smell. 

Remedy: the best solution to this is to ensure your drains are far from the trees on your compound. Unfortunately, this is not always possible.  

The next best cause of action is to get tree removalists to your property. They can find ways to remove the tree roots from your drains with minimal damage to the offending tree. 

Sewer Smells and Plumbing Issues

You can get an odour that smells like the sewer. This is usually from a cracked pipe or leak in your sewer. 

Poor plumbing can cause drain smells as well. Errors during installation can affect traps and vents and the overall functioning of a drain. The same goes for rotting drain tubes. 

Remedy: this isn't easy to DIY. If your sewer seems to be the problem, you need to get professional plumbers to look at your entire drainage and sewerage system. They will bring tools to help them accurately identify the leak's source and advise on the best cause of action. 

For plumbing issues, getting your plumbing done by a reputable, professional plumbing company is your best bet against future problems. But, again, this is not always in your control. 

You might buy a house with bad plumbing, or your plumbing might do through natural wear and tear over time. Call a plumber as soon as you suspect you might have a plumbing problem. 

It might also help to have occasional inspections from a qualified plumber. This might help identify and resolve potential issues long before they cause problems.
