Nobody wants their home to smell bad, but finding the culprit can be tricky if the source of the odour is coming from your drains! Whether you’re dealing with bathroom sink smells or clogged garbage disposal in your kitchen, these problems can disrupt daily life and indicate underlying issues with your plumbing system.
Fortunately, with a bit of investigation, drain cleaning, and the expertise and reliability of Brampton plumbing experts, you can eliminate those sink drain smells and get your home selling fresh once again.
What Causes Bad Sink Drain Smells?
1. Biological Buildup
Organic matter, such as food particles, grease, hair, and soap scum, can accumulate inside the bathroom or kitchen sink and stop it from draining. When these substances become trapped in the pipes, they provide an ideal environment for bacteria and other microorganisms to thrive.
As organic matter decomposes, it releases foul-smelling gases, such as hydrogen sulphide and methane, which contribute to the unpleasant odour emanating from drains. This biological buildup not only causes bad smells but can also lead to drain clogs and other common plumbing issues if left unchecked.
2. Dry P-Trap
The P-trap is a U-shaped pipe located beneath sinks, showers, and other plumbing fixtures. Its primary function is to prevent sewer gasses from entering the home by creating a water seal that acts as a barrier. When water flows through the drain, it fills the P-trap, creating a seal that blocks the passage of odorous gasses from the sewer system.
However, if a plumbing fixture is not used regularly (such as a shower drain in a downstairs bathroom), the water in the P-trap can evaporate, leaving the trap dry. When this happens, the seal is broken, allowing sewer gases to enter the home through the drain. As a result, you may have smelly drains in the affected fixture.
To remedy this issue, simply run water down the drain periodically to refill the P-trap and maintain the water seal.
3. Venting Issues
Proper venting is essential for maintaining proper airflow and pressure within your plumbing system. Vent pipes extend from your drainage system to the exterior of your home, allowing sewer gases to escape safely into the atmosphere.
Vents also provide a pathway for air to enter the plumbing system, facilitating drainage and preventing suction that can lead to slow drains and gurgling noises.
When vent pipes become obstructed or improperly installed, they can create negative pressure within the drainage system, causing sewer gases to be drawn into the home through drains. This can result in smelly sink drains, as the odours permeate throughout your house.
Common causes of venting issues include blockages caused by debris or animal nests, as well as inadequate vent pipe sizing or placement.
Addressing venting issues typically requires the expertise of a professional Georgetown plumber to inspect and repair the vent pipes to ensure proper airflow and ventilation within your plumbing system.
DIY Solutions to Try Before Calling a Professional
1. Hot Water and Dish Soap Technique
This simple method involves flushing hot water mixed with dish soap down the drain.
- Start by heating water to near boiling point.
- Add a few tablespoons of dish soap to the hot water and mix well. The hot water helps to break down grease and other organic matter, while the dish soap helps to loosen debris clinging to the sides of the pipes.
- Pour the boiling water mixture down the clogged drain and let it sit for several minutes.
- Finally, flush the kitchen drain with hot or boiling water to rinse away any remaining residue.
2. Baking Soda and Vinegar
Baking soda and vinegar create a natural chemical reaction that can help clean and deodorize drains.
- Pour baking soda into the kitchen sink (about ½ cup)
- Next, pour about ½ cup of vinegar into the smelly sink.
- Allow the baking soda mixture to fizz and bubble for several minutes. This reaction helps to loosen and dislodge buildup within the pipes.
- After the fizzing has subsided, flush the drain with hot water to wash away any remaining residue.
- This method can be repeated periodically to maintain clean and odour-free drains.
3. Enzyme Cleaners
Enzyme-based drain cleaners are a natural alternative to harsh chemical cleaners and can help break down organic matter without damaging your pipes.
These cleaners contain enzymes that target and digest organic material, such as grease, hair, and food particles, effectively clearing clogs and eliminating odours.
- Simply pour the recommended amount of enzyme cleaner down the drain with the bad smell and allow it to work overnight or as directed on the product label.
When used regularly, enzyme cleaners are particularly effective for preventing future clogs and maintaining the health of your plumbing system.
4. Check the P-trap
The P-trap is a common location for clogs and can become dry if unused for too long, allowing gases (and the accompanying sewer smell) to enter the home.
- To check the P-trap, locate the curved pipe beneath the sink or fixture.
- Place a bucket or towel underneath the P-trap to catch any water or debris.
- Loosen the slip nuts on either side of the P-trap using a pipe wrench or adjustable pliers.
- Carefully remove the P-trap and inspect it for clogs or buildup.
- Clean out any debris or buildup using a brush or pipe cleaner.
- Once clean, reassemble the P-trap and ensure that the slip nuts are tightened securely.
- Finally, run water down the drain to refill the P-trap and restore the water seal, preventing sewer odours from entering the home.
