Best Practices for Preventing Clogged Drains & Sewer Backups

Clogged drains and sewer backups can lead to costly repairs, unpleasant odors, and potential water damage. By following a few simple best practices, homeowners and businesses can keep their plumbing systems running smoothly. Here’s what you need to know to prevent blockages and maintain healthy drains.

Everyday Preventative Measures

1. Be Mindful of What Goes Down the Drain
  • DO NOT pour grease, oils, or fats down the kitchen sink. These substances harden over time and cause blockages.
  • Dispose of food scraps properly—use a strainer to catch debris and throw it in the trash or compost.
  • Only flush toilet paper and human waste—avoid flushing wipes, paper towels, hygiene products, or cotton swabs.
2. Use Drain Screens
  • Install mesh drain screens in sinks, tubs, and showers to catch hair, soap scum, and debris before they enter your pipes.
  • Clean screens regularly to maintain effectiveness.
3. Run Hot Water After Each Use
  • Let hot water run for 30 seconds after using the sink to help flush away minor buildups of grease and soap residue.

Routine Maintenance

4. Flush Drains with Baking Soda & Vinegar
  • Pour 1/2 cup of baking soda, followed by 1 cup of vinegar, down the drain.
  • Let it sit for 15 minutes before flushing with hot water.
  • This natural method helps break down buildup and keep pipes fresh.
5. Regularly Clean Your Garbage Disposal
  • Run ice cubes and a few lemon peels through the disposal to keep blades sharp and eliminate odors.
  • Avoid putting fibrous or starchy foods (e.g., celery, potato peels) down the disposal, as they can cause clogs.
6. Use Enzyme-Based Drain Cleaners
  • Monthly use of enzyme-based cleaners can break down organic material safely without damaging pipes.
  • Avoid chemical drain cleaners, as they can corrode plumbing over time.

Outdoor Drain & Sewer Line Protection

7. Keep Tree Roots Away from Sewer Lines
  • Tree roots can infiltrate underground pipes, leading to severe blockages.
  • If planting trees near sewer lines, choose slow-growing species with non-invasive root systems.
  • Consider scheduling an annual sewer line inspection with a plumber.
8. Clear Gutters & Outdoor Drains
  • Keep gutters and storm drains free of leaves and debris to prevent water buildup and potential backups.
  • Install gutter guards to minimize accumulation of leaves and dirt.

When to Call a Professional

If you notice any of the following signs, it may be time to call a plumber:

  • Frequent slow-draining sinks or tubs
  • Gurgling noises from drains or toilets
  • Recurring sewage odors
  • Multiple drains clogging at the same time

Preventing clogged drains and sewer backups is easier than dealing with costly repairs and water damage. By following these best practices, you can keep your plumbing system in top shape and avoid unnecessary headaches. Regular maintenance and mindful usage go a long way in preventing plumbing issues before they start.
