Unblocking Sewer Lines: Strategies for Removing Grease Buildup

Grease buildup in sewer lines is a common issue that can lead to clogs, backups, and unpleasant odors. Addressing this problem promptly is essential to prevent costly damage and ensure the smooth operation of your plumbing system. Here, we explore effective methods for removing grease from sewer lines with insights from a plumber in Auburn, GA.

Understanding the Problem

  • Causes of Grease Buildup: Grease accumulates in sewer lines primarily from the disposal of fats, oils, and grease (FOG) down drains. Over time, FOG solidifies and adheres to the walls of the pipes, restricting flow and causing blockages.
  • Consequences of Grease Blockages: Blockages in the sewage system can result in unpleasant smells emanating from the property’s outside, as well as sewage backups and overflowing toilets. Additionally, grease buildup increases the risk of pipe corrosion and structural damage.

Effective Grease Removal Methods

  • Hydro Jetting

Hydrojetting involves using high-pressure water to scour the interior walls of sewer lines, effectively breaking up and flushing away grease deposits. This technique works wonders to clear up obstinate obstructions and get the flow back to normal.

  • Enzyme Drain Cleaners

Enzyme-based drain cleaners contain bacteria and enzymes that feed on organic matter, including grease. When poured down the drain, these cleaners break down grease buildup over time, preventing future clogs and maintaining clear sewer lines.

  • Mechanical Snaking

Mechanical snaking, or drain augering, involves using a flexible cable with an auger attachment to physically break apart and remove grease blockages from sewer lines. This method is suitable for smaller, localized clogs and is often used in conjunction with other cleaning techniques.

  • Chemical Drain Cleaners

Chemical drain cleaners are formulated to dissolve grease, hair, and other organic materials that contribute to clogs in sewer lines. While effective in some cases, these cleaners can be harsh on pipes and may pose environmental concerns, so they should be used with caution.

Preventative Maintenance Tips

  • Proper Waste Disposal: Dispose of FOG properly by collecting it in a container and disposing of it in the trash rather than pouring it down the drain.
  • Regular Inspections: Schedule regular inspections of your sewer lines to identify and address grease buildup and other potential issues before they escalate.
  • Grease Traps: Install and maintain grease traps in commercial kitchens and food service establishments to capture FOG before it enters the sewer system.


Grease buildup in sewer lines is a pervasive problem that requires proactive solutions to prevent blockages and maintain the integrity of your plumbing system. By understanding the causes of grease buildup and implementing effective removal methods such as hydrojetting, enzyme drain cleaners, mechanical snaking, and chemical drain cleaners, you can keep your sewer lines clear and flowing smoothly.
