How to flush out a sewer drain and eliminate sewage smell

Experiencing a sewage smell in your basement or laundry room can be both unpleasant and concerning. The root cause of this issue is often a buildup of debris, clogs, or bacterial growth in your sewer drain. This knowledge base article is designed to provide tenants with a stepbystep guide on how to effectively flush out their sewer drain and eliminate the sewage smell, ensuring a cleaner and more comfortable living environment.

Before You Begin:

Before attempting any DIY solutions, make sure to take these precautions:

1. Safety First: Wear appropriate protective gear, such as gloves and goggles, to prevent contact with any potentially harmful substances.
2. Ventilation: Ensure proper ventilation by opening windows or using fans to minimize exposure to foul odors.
3. Consult Your Landlord: Inform your landlord or property manager about the issue before attempting any solutions. Some situations may require professional assistance.

Materials Needed:

• Boiling water
• Baking soda
• Vinegar
• Plunger
• Bucket
• Rubber gloves
• Long-handled brush or plumbing snake
• Enzyme-based drain cleaner (optional)

Step-by-Step Guide:

1. Boiling Water:
   1. Begin by pouring a large pot of boiling water down the drain. This can help break down grease and debris that might be causing the odor. 
   2. In some cases, you may not need to continue beyond this point if the smell does not persist.
2. Baking Soda and Vinegar:
   1. Start by pouring about half a cup of baking soda down the drain.
   2. Follow this with a mixture of one cup of vinegar and one cup of hot water. The chemical reaction between the baking soda and vinegar can help break down any buildup.
   3. Allow the mixture to sit for about 15 minutes before rinsing the drain with another pot of boiling water.
3. Plunger:
   1. Use a plunger specifically designed for sinks to create a seal over the drain. Plunge vigorously several times to dislodge any stubborn clogs.
   2. Repeat this process a few times if necessary.
4. Plumbing Snake or Brush:
   1. If the smell persists, you may need to physically remove the clog or debris using a plumbing snake or a long-handled brush. Insert the snake or brush into the drain and rotate or push it through to break up the obstruction.
5. Enzyme-Based Drain Cleaner (Optional):
   1. If the odor remains, consider using an enzyme-based drain cleaner. These cleaners contain helpful bacteria that can break down organic matter and eliminate odors. Follow the manufacturer's instructions on the product label.
   2. Do not use bleach or other products that may harm your eyes or lungs.
6. Regular Maintenance:
   1. To prevent future sewage smell issues, practice regular maintenance by avoiding pouring grease, large food particles, and nonbiodegradable items down the drain. Use drain strainers to catch debris and clean them regularly.

Flushing out your sewer drain and eliminating sewage smells in your basement or laundry room is manageable with the right tools and techniques. By following this step-by-step guide and practicing proper maintenance, you can enjoy a fresh and odor-free living space. If the issue persists or becomes more complex, don't hesitate to contact your landlord or a professional plumber for assistance.
