Understanding the Causes and Solutions

A smelly drain can be quite unpleasant and is often an indication of an underlying issue within your plumbing system. Drains are designed to prevent the foul odours of biodegradable and compostable materials from permeating into your living space. When you notice a persistent smell coming from your drain, it’s crucial to identify the root cause and take appropriate measures to address it.

In this blog post, we will explore common reasons why drains make unpleasant odours and provide practical solutions to eliminate these smells.

Clogs and Blockages:

One of the primary reasons for a smelly drain is the presence of clogs or blockages within the pipes. When debris, hair, grease, or food particles accumulate over time, they can obstruct the proper flow of water. These substances provide a breeding ground for bacteria, which release foul-smelling gases as they break down the organic matter. If you notice an unpleasant odor emanating from your shower or kitchen sink, a clog or blockage is likely the culprit.

Solution: To address clogs and blockages, you can try using a plunger or a drain snake to remove the obstruction manually. Chemical drain cleaners are an option, but they should be used sparingly as they can be harsh on your pipes. Regular preventive measures like using drain covers to catch debris and regularly cleaning drains can help prevent future clogs.

Hair Build-up in Shower Drains:

In the case of shower drains, a common cause of unpleasant odours is a buildup of hair in the drain trap. As you wash your hair, loose strands can accumulate in the drain and combine with soap scum, dead skin cells, and other debris. Over time, this mixture can create a blockage and emit a foul smell.

Solution: To tackle hair build-up, consider using a drain strainer or cover that can trap hair before it enters the drain. Regularly clean the drain cover and remove any accumulated hair. For more stubborn clogs, you may need to use a drain snake or seek professional assistance.

Does Pouring Oils And Fats Into Drains Cause Clogs In Pipes?

Grease and Food Build-up in Kitchen Sinks:

Kitchen sinks are prone to developing unpleasant odours due to the accumulation of grease, oils, and food particles. When these substances are washed down the drain, they can stick to the pipe walls and create a breeding ground for bacteria. As the bacteria break down the organic matter, they produce foul-smelling gases.

Solution: Avoid pouring excessive grease, oils, and food scraps down the drain. Instead, scrape plates and utensils into the trash or compost bin before washing them. Use sink strainers to catch food particles and empty them regularly. Regularly flushing your drain with hot water and vinegar can help dissolve grease and eliminate odours.

Dry Water Seals:

A less common but possible cause of smelly drains is dry water seals in floor wastes. Floor wastes, also known as floor drains, are typically found in areas such as bathrooms, laundry rooms, or basements. These drains have a water seal that prevents sewer gases from entering your home. If the water seal evaporates or dries out, odours can escape through the drain.

Solution: To restore the water seal, pour a bucket or two of water down each floor waste drain periodically. This replenishes the water barrier and blocks the passage of unpleasant smells.

In summary, a smelly drain indicates an underlying issue within your plumbing system. By understanding the common causes and implementing the suggested solutions, you can eliminate foul odours and maintain a healthy and pleasant environment in your home. Remember to practice preventive measures, such as using drain covers, regular cleaning, and avoiding the improper disposal of debris, to minimize the occurrence of smelly drains. If the problem persists or becomes severe, it is advisable to consult a professional plumber for further assistance.
