Dealing with drain smells, heres how to get rid of them!

Smelly drains are a common problem, but you don’t have to live with them. Wondering how to get rid of the bad odour? This article covers the common causes of smelly drains and easy DIY fixes to help you eliminate the smell and keep your drains fresh.

Key Takeaways

  • Smelly drains are usually caused by food particles, grease, soap scum, hair, and sewer gases from dry P-traps.
  • DIY solutions like boiling water, baking soda with vinegar, and regular drain maintenance can effectively eliminate odors.
  • If smells persist despite DIY methods, it may indicate structural plumbing issues or deeper problems that require a professional plumber.

Common Causes of Smelly Drains

Understanding the common causes of a smelly drain can help address the problem effectively. Knowing the source of the problem can help you tackle it more effectively. Smelly drains are often caused by the buildup of food particles and grease, soap scum and hair, and sewer gases.

Food particles and grease from leftover food can accumulate in kitchen drains, leading to bad smells. Soap scum and hair buildup in bathroom sinks and shower drains can emit foul odors, especially when combined with body oils. Sewer gases can escape through dry P-traps or broken vent pipes, resulting in a characteristic smell of rotten eggs.

Each of these causes contributes to unpleasant drain smells in different ways.

Food Particles and Grease

Leftover food can accumulate in drains, leading to blockages and the development of bad smells. Cooking oils and fats should never be poured down the drain as they lead to blockages. Instead, scrape food particles off plates and dispose of them in the trash before rinsing dishes.

Avoid disposing of non-decomposable items down the drain to prevent blockages that can lead to unpleasant smells. Being mindful of what goes down your kitchen drains reduces the chances of developing unpleasant odours.

Soap Scum and Hair

Hair and soap residue often combine in drains, resulting in clogs that emit foul odors. Personal care products like shampoo, shaving cream, and body oils contribute to the buildup of soap scum and hair in shower drains.

Hair, soap, and other personal care products commonly cause odors in shower drains. Regularly cleaning your drains and removing hair can help prevent these clogs and the associated bad smells.

Sewer Gases

Sewer gases, primarily composed of hydrogen sulfide, have a distinct rotten egg smell, often described as a sewer gas smell. A common cause of sewer gases escaping is a dry P-trap, which prevents the trapping of water needed to create a seal.

Improperly installed or obstructed vent pipes can cause sewer gases to enter the home. Unblocked and correctly installed vent pipes prevent sewer gas buildup and odors.

Here are some DIY methods to eliminate unpleasant drain odours:

  4. Lemon

Start with the simplest solution and progress if it fails.

When using a drain cleaner, choose one with a thick gel formula for effective cleaning. If the problem persists, you might need to use a drain snake or call a professional plumber. Here are some specific DIY methods.

Baking Soda and Vinegar

Baking soda and vinegar are common household items that can effectively neutralise odours in drains. To use this method, pour one cup of baking soda down the drain, followed by two cups of hot vinegar. Let it fizz for an hour before flushing with hot tap water.

White vinegar is effective for eliminating unpleasant odours in drains, especially kitchen sinks. This method can be applied not only to kitchen sinks but also effectively addresses sewage odours in bathroom drains.

Boiling Water

Pouring boiling water down the drain can aid in dissolving clogs and reduce unpleasant smells. This method is particularly effective for clearing minor blockages in a smelly kitchen sink.

Pour boiling water down the drain, then follow with cold water to solidify any remaining gunk. Repeat as necessary to keep the drain clear and odor-free.

Drain Snake

A drain snake is an effective tool for clearing stubborn clogs that contribute to drain smells and clogged drain odors. To use a drain snake, insert it into the drain and rotate it to catch and remove the clog.

If the clog persists and you still have a drain smell, consider using a professional drain snake or calling a plumber for assistance. Keeping your drains clear of debris will help maintain a fresh and pleasant-smelling home.

How to Clean Specific Smelly Drains

Different types of drains require specific cleaning methods to effectively eliminate odours.

Here are methods to get rid of a smelly drain and clean your kitchen sink drains, bathroom sinks, and shower drains to maintain freshness.

Kitchen Sink Drain

Before cleaning the P-trap, wear rubber gloves for protection. Rinse the P-trap outside using a garden hose for effective cleaning. After cleaning, keep the wastewater and gunk in a bucket for proper disposal.

Pour boiling water down the drain as a first step to help eliminate odors. After pouring hot water, use cold water to solidify any remaining gunk. For stubborn clogs, use a drain snake or straighten a wire coat hanger with one end having a hook.

Bathroom Sink

Hair and soap residue can accumulate in bathroom sink drains, leading to unpleasant smells. Common materials that contribute to bathroom drain blockages include toothpaste, hair, and soap.

A mix of half water and half chlorine bleach is recommended for eliminating odors in the sink overflow area. Regular cleaning and using drain cleaners can prevent odors in a bathroom sink.

Shower Drain

Use your hands to remove visible debris if it’s at the surface level. Pour hot water down the shower drain to help dissolve any remaining clogs. A plunger can be effective in creating suction to dislodge clogs.

If the clog persists, use a drain snake to reach deeper blockages. Flushing the shower drain with a solution of baking soda, vinegar, and lemon can neutralise odours. Regularly removing hair and using deodorising solutions helps prevent future clogs and odours.

Preventing Future Smelly Drains

Preventing future clean smelly drains involves regular maintenance, proper disposal practices, and professional inspections. Implementing these measures can significantly enhance drain hygiene and keep your home smelling fresh finally getting rid of that smelly drain.

Regular Maintenance

Regular cleaning routines and proper use of drain cleaners can help prevent odours in bathroom sink drains. Using strainers effectively captures debris, preventing buildup that leads to smelly drains.

Flushing your drains with boiling water regularly can prevent debris buildup that causes odors. Commonly used methods to eliminate drain odors include bleach, vinegar, and baking soda.

Proper Disposal Practices

Scrape and rinse dishes before loading them in the dishwasher to prevent food particles from clogging the drain. Leftover cooking oils should be cooled and placed in a disposable container for proper disposal.

Flushing non-degradable items like baby wipes can cause septic blockage leading to sewage smells. Proper disposal practices significantly reduce the risk of developing smelly drains.

Professional Inspections

Scheduling regular professional inspections can help detect drainage problems early before they worsen. Qualified plumbers can detect potential drainage problems before they escalate into serious issues.

Routine professional inspections can uncover hidden problems like misaligned pipes or root intrusion. Regular inspections ensure your plumbing system stays in good condition, preventing smelly drains.

When to Call a Professional Plumber

While DIY methods can be effective, there are times when calling a professional plumber is necessary. Persistent odours, structural plumbing issues, and sewer line problems are all indicators that you need expert assistance. At Homecure Plumbers, we have dedicated drainage engineers who specialise in clearing drain smells and blockages so when you need us we can clear a smelly drain fast.

Persistent Odours

If unpleasant drain smells persist despite using DIY cleaning methods, it may indicate deeper issues that require a professional’s attention. Contact a professional plumber if the smell continues after attempts to refill the P-trap.

If odours remain after cleaning the sink overflow, it is advisable to get a professional plumbing service involved. Persistent sewage smells that do not disappear after cleaning need immediate professional attention.

Structural Plumbing Issues

If you suspect a leaking pipe causing a smelly drain, contact a plumber. Common causes of leaky pipes include loose fittings and perforations due to corrosion.

A broken vent pipe requires immediate attention. It’s important to contact a professional for assistance. Promptly addressing structural plumbing issues can prevent further damage and foul smells.

Sewer Line Problems

Signs like gurgling sounds or persistent odours may point to sewer line disruptions that need immediate intervention. Sewage gas buildup due to clogs can cause a rotten egg smell in outdoor drains.

Plumbing experts can resolve sewer line problems. Homecure Plumbers London, for instance, use advanced equipment like high-pressure jetting and commercial-grade snaking tools to clear a smelly drain and blockage quickly and effectively.

Summary

In summary, smelly drains can be caused by various factors, including food particles and grease, soap scum and hair, and sewer gases. DIY methods like using baking soda and vinegar, boiling water, and a drain snake can help eliminate odors. Specific cleaning techniques for kitchen sinks, bathroom sinks, and shower drains are essential for maintaining a fresh-smelling home.

Preventing future smelly drains involves regular maintenance, proper disposal practices, and professional inspections.
