How to Get Rid of a Smelly Drain (2024)

Getting rid of a smelly drain is a common issue that can often be resolved with a few simple steps. Here’s a detailed explanation of how a local plumber might tackle this problem:

1. Identify the Source:

The first step is to identify what is causing the unpleasant odor. Smelly drains can be caused by various factors, including trapped food debris, grease buildup, mold or mildew growth, or a dry drain trap.

1. Inspect the Drain Opening: The plumber begins by visually inspecting the drain opening for any visible signs of debris, slime, or buildup. They use a flashlight to illuminate the drain and look for any obvious sources of odor, such as rotting food particles or hair.


2. Check for Biofilm Buildup: Biofilm, a slimy layer of bacteria and organic matter, often accumulates on the walls of drain pipes and can emit foul odors. The plumber may use a drain camera to inspect the inside of the pipes for biofilm buildup, especially in hard-to-reach areas.


3. Assess the Drain Trap: The P-trap, a curved section of pipe beneath the sink, is a common location for debris buildup and foul odors. The plumber carefully removes the trap to inspect it for any blockages or residue. They check for signs of dryness, as a dry trap can allow sewer gases to escape into the home.


4. Investigate Venting Issues: In some cases, smelly drains may be caused by venting problems in the plumbing system. The plumber checks the vent stack on the roof to ensure it’s clear of obstructions and functioning properly. A blocked vent can lead to slow drainage and odors backing up into the home.


5. Consider Other Factors: Smelly drains can also be caused by factors such as mold or mildew growth in the pipes, sewer line blockages, or even a malfunctioning garbage disposal. The plumber considers these possibilities and conducts a thorough inspection to rule out any underlying issues.

By systematically identifying the source of the smelly drain, the plumber can develop an effective plan to eliminate the odor and restore proper drainage. This step is essential for targeting the root cause of the problem and preventing it from recurring in the future.

2. Clean the Drain:

Cleaning the drain is essential for removing any buildup of organic matter, debris, or bacteria that may be causing the unpleasant odor. Here’s how a plumber would typically approach this step:

1. Remove Visible Debris: Start by visually inspecting the drain opening for any visible signs of debris, such as food particles, hair, or soap scum. Use a pair of gloves and a drain brush or wire to remove any gunk or buildup from the drain grate or stopper.


2. Flush with Hot Water: Once the visible debris has been cleared, flush the drain with hot water. Hot water helps to loosen and wash away any remaining organic matter or residue clinging to the walls of the pipes. Allow the hot water to run for several minutes to thoroughly flush out the drain.


3. Scrub the Drain: For stubborn buildup or residue, the plumber may use a drain brush or pipe cleaning tool to scrub the inside of the drain pipes. They carefully insert the brush into the drain opening and use a back-and-forth motion to dislodge any buildup clinging to the walls.


4. Use Bio-Enzymatic Cleaners: Bio-enzymatic drain cleaners contain specialized bacteria and enzymes that break down organic matter, such as grease, food particles, and hair, into smaller, odorless compounds. The plumber may recommend using a bio-enzymatic cleaner to effectively clean and deodorize the drain.


5. Allow Time to Work: After applying the bio-enzymatic cleaner, the plumber advises letting it sit in the drain for the recommended amount of time as per the product instructions. This allows the bacteria and enzymes to penetrate deep into the pipes and break down stubborn organic matter.


6. Rinse Thoroughly: Once the cleaner has had time to work its magic, rinse the drain thoroughly with hot water to flush away the dissolved debris and residual cleaner. Run the water for several minutes to ensure the drain is completely clear and odor-free.


7. Repeat if Necessary: In cases of severe buildup or persistent odors, the plumber may recommend repeating the cleaning process multiple times or using a combination of cleaning methods to achieve the desired results.

By thoroughly cleaning the drain, the plumber effectively removes the source of the odor and restores proper drainage. This step is crucial for eliminating foul odors and preventing them from recurring in the future.

3. Use Baking Soda and Vinegar:

Using baking soda and vinegar is a popular and environmentally friendly method for getting rid of a smelly drain. Here’s how a plumber might explain this point in detail. Baking soda and vinegar are natural ingredients that can help neutralize odors and break down organic matter in the drain. Here’s how a plumber would typically recommend using this method:

1. Pour Baking Soda Down the Drain: Start by pouring about half a cup of baking soda down the smelly drain. Baking soda, also known as sodium bicarbonate, acts as a mild abrasive and helps to absorb odors.


2. Follow with White Vinegar: After pouring the baking soda, pour about half a cup of white vinegar down the drain. White vinegar, or acetic acid, reacts with the baking soda to produce a foaming action that helps dislodge debris and neutralize odors.


3. Cover the Drain Opening: Immediately after pouring the vinegar, cover the drain opening with a stopper, sink plug, or a cloth. This step is essential as it contains the foaming reaction inside the drain, allowing it to work more effectively.


4. Let It Sit: Leave the baking soda and vinegar mixture to work its magic for at least 30 minutes. You can leave it for longer, even overnight, for more stubborn odors.


5. Flush with Hot Water: After the waiting period, remove the cover from the drain and flush it with hot water. Hot water helps to wash away the dissolved debris and residual baking soda and vinegar.


6. Repeat if Necessary: For particularly stubborn odors or persistent clogs, you may need to repeat the baking soda and vinegar treatment or combine it with other cleaning methods, such as scrubbing the drain or using a bio-enzymatic cleaner.

Tips:

• To enhance the cleaning power of baking soda and vinegar, you can add a few drops of essential oils, such as lemon or tea tree oil, which have natural antimicrobial properties.
• Regular maintenance with baking soda and vinegar can help prevent smelly drains from recurring. Consider using this method monthly as a preventive measure.

By using baking soda and vinegar, you can effectively neutralize odors and break down organic matter in the drain, leaving it smelling fresh and clean. This natural and eco-friendly method is safe for most types of pipes and can be used regularly to maintain odor-free drains.

4. Check the Drain Trap:

Checking the drain trap is an important step in getting rid of a smelly drain, as it’s a common location for buildup and residue that can contribute to unpleasant odors. Here’s how a plumber might explain this point in detail:

The drain trap, also known as the P-trap, is a curved section of pipe located beneath the sink or fixture. It’s designed to hold water to create a seal that prevents sewer gases from backing up into the home. However, the drain trap can also become a trap for debris and residue, leading to foul odors. Here’s how to check and clean the drain trap:

1. Turn Off the Water: Before starting any work, turn off the water supply to the sink or fixture. You can usually find shut-off valves beneath the sink or at the main water supply.


2. Prepare the Area: Clear out the area under the sink and place a bucket or towel beneath the drain trap to catch any water or debris that may spill out during the process.


3. Remove the Drain Trap: Using a pair of adjustable pliers or a pipe wrench, carefully loosen the slip nuts on either side of the drain trap. Place a bucket or bowl beneath the trap to catch any water or debris that may spill out.


4. Inspect the Trap: Once the drain trap is removed, inspect it for any buildup of debris, slime, or residue. This can include food particles, grease, hair, soap scum, and other organic matter. Use a flashlight to illuminate the inside of the trap and look for any signs of buildup.


5. Clean the Trap: If the drain trap is dirty or clogged, clean it thoroughly with hot, soapy water and a brush or pipe cleaner. Scrub the inside of the trap to remove any stubborn buildup or residue. You can also use a mixture of baking soda and vinegar to help break down grease and organic matter.


6. Check the Trap Arm: While the trap is removed, inspect the trap arm, the horizontal pipe that connects the trap to the wall or main drain line. Look for any signs of blockages or buildup, such as grease or soap scum.


7. Reassemble the Drain Trap: Once the trap is clean and free of debris, reassemble it by tightening the slip nuts on either side. Be careful not to overtighten the nuts, as this can cause damage to the pipes.


8. Test for Leaks: Turn the water supply back on and run water down the drain to test for leaks. Check for any signs of water dripping or pooling beneath the sink.

By checking and cleaning the drain trap, you can effectively remove buildup and residue that may be contributing to the smelly drain. This step is essential for maintaining proper drainage and preventing foul odors from recurring in the future.

5. Use Enzyme Cleaners:

Using enzyme cleaners is an effective method for getting rid of a smelly drain, as they contain specialized bacteria and enzymes that break down organic matter, such as grease, food particles, and hair, into smaller, odorless compounds. Here’s how a plumber might explain this point in detail:

Use Enzyme Cleaners:

Enzyme-based drain cleaners are a safe and eco-friendly option for eliminating foul odors and clearing blockages in drains. Here’s how to use enzyme cleaners effectively:

1. Select an Enzyme Cleaner: Choose a high-quality enzyme cleaner specifically formulated for use in drains and plumbing systems. Look for products that contain a blend of beneficial bacteria and enzymes designed to target organic matter and neutralize odors.


2. Read the Instructions: Before using the enzyme cleaner, carefully read and follow the manufacturer’s instructions provided on the product label. Pay attention to any safety precautions or usage guidelines to ensure effective and safe application.


3. Prepare the Cleaner: If the enzyme cleaner comes in a concentrated form, dilute it with water according to the manufacturer’s instructions. Use a bucket or container to mix the cleaner with water to the recommended ratio.


4. Pour into the Drain: Pour the diluted enzyme cleaner directly into the smelly drain, ensuring that it reaches the affected area. You may need to use a funnel or pour spout to accurately direct the cleaner into the drain opening.


5. Allow Time to Work: Once the enzyme cleaner is poured into the drain, allow it to sit undisturbed for the recommended duration specified on the product label. This allows the beneficial bacteria and enzymes to penetrate deep into the drain pipes and break down organic matter.


6. Flush with Water: After the designated waiting period, flush the drain with hot water to rinse away the dissolved debris and residual cleaner. Run the water for several minutes to ensure thorough flushing and to remove any remaining odors.


7. Repeat if Necessary: For stubborn odors or persistent blockages, you may need to repeat the enzyme cleaning process multiple times or use a higher concentration of cleaner. Follow the manufacturer’s recommendations for additional applications.


8. Maintenance: Consider using enzyme cleaners regularly as part of your drain maintenance routine to prevent foul odors and keep your drains running smoothly. Regular treatments can help maintain a healthy balance of beneficial bacteria in the plumbing system.

By using enzyme cleaners, you can effectively break down organic matter, neutralize odors, and restore proper drainage in your smelly drain. This natural and eco-friendly method is safe for most types of pipes and can be used regularly to maintain odor-free drains.

6. Schedule Regular Maintenance: Full-Service Sewer Smell

Regular maintenance is essential for preventing smelly drains and ensuring the proper functioning of your plumbing system. Here’s how to incorporate regular maintenance into your routine:

1. Establish a Maintenance Schedule: Set up a regular maintenance schedule for your drains, ideally on a monthly or quarterly basis, depending on your usage and the severity of previous issues. Consistency is key to maintaining clean and odor-free drains.


2. Perform Routine Inspections: Regularly inspect your drains for any signs of buildup, debris, or foul odors. Check the drain openings, traps, and pipes for any visible signs of residue or blockages. Address any issues promptly before they worsen.


3. Clean Drains Periodically: As part of your maintenance routine, clean your drains periodically using methods such as baking soda and vinegar, enzyme cleaners, or mechanical cleaning tools like drain brushes or snakes. These methods help remove organic matter, grease, and residue that can contribute to foul odors.


4. Flush Drains with Hot Water: Regularly flush your drains with hot water to help prevent the buildup of grease, soap scum, and other debris. Hot water helps to dissolve and wash away these substances, keeping your drains clean and odor-free.


5. Use Preventive Products: Consider using preventive products such as enzyme-based drain cleaners or drain maintenance treatments. These products contain beneficial bacteria and enzymes that help break down organic matter and prevent odors from developing.


6. Address Plumbing Issues Promptly: If you notice any plumbing issues such as slow drainage, gurgling sounds, or foul odors, address them promptly to prevent them from worsening. Ignoring minor issues can lead to more significant problems down the line.


7. Consult a Professional Plumber: For more comprehensive maintenance and inspection, consider hiring a professional plumber to assess your plumbing system periodically. A plumber can identify potential issues early on and recommend preventive measures to keep your drains clean and odor-free.


8. Educate Household Members: Educate members of your household about proper drain maintenance practices, such as avoiding pouring grease or oil down the drain, using drain strainers to catch debris, and disposing of food scraps in the trash instead of the sink.

By scheduling regular maintenance for your drains, you can proactively prevent smelly drains and ensure the proper functioning of your plumbing system. Consistent maintenance helps to keep your drains clean, odor-free, and in good working condition, saving you time, money, and hassle in the long run.
