What Causes Sewer Line Blockages in the First Place?

It’s essential to understand what causes sewer line blockages. Common culprits include the following:

Non-Flushable Items

Items like baby wipes, sanitary products, and paper towels do not disintegrate like toilet paper and can quickly lead to clogs.

Grease Buildup

Grease from cooking can solidify inside pipes, gradually narrowing the passage until it becomes completely blocked.

Tree Root Intrusion

Tree roots can grow into cracks and joints of sewer lines, blocking and sometimes breaking the pipes.

Aging Pipes

Older pipes made from clay or other porous materials can crack and deteriorate, leading to collapses that block the sewer line.

Misaligned Pipes

Shifting soil or improper installation can misalign pipes, creating areas where debris accumulates and causes blockages.

Clogged Sewer Lines Need Professional Intervention

Can a sewer line unclog itself? Typically, no.

When faced with a clogged sewer line, professional intervention is often necessary. Plumbing professionals know how to quickly locate the clog and restore normal flow.

Depending on the type and severity of your sewer line clog, professionals may use one of many different clog-removal techniques after using a camera inspection to find the problem:

  • Hydro Jetting: This method uses high-pressure water jets to thoroughly clean sewer pipes, effectively removing grease, sludge, and other debris.
  • Mechanical Snaking: A flexible metal cable, often fitted with a blade or auger, physically breaks up clogs within the pipe.
  • Pipe Bursting: For severely damaged pipes, your plumber may pull a new pipe through the old one, simultaneously fracturing the old pipe and replacing it with a new one.
  • Pipe Relining: With this trenchless repair method, professionals insert a resin-coated liner into the pipe. It then hardens and forms a new pipe within the old, damaged one.

Preventative Measures and Maintenance

Prevention is key to avoiding sewer line blockages. Regular maintenance, including professional inspections and cleanings, can prevent the accumulation of debris that leads to clogs.

For those with septic systems, understanding how to care for your septic system is vital in preventing backups and maintaining system health. Regular pumping of the septic tank, typically every three to five years, depending on usage, ensures that solids do not enter the drain field and cause blockages.

To prevent toilet water from overflowing and other issues that often come with a clogged sewer line, consider the following preventative measures:

  • Use drain strainers: Placing strainers in kitchen sinks, bathroom sinks, and showers can trap food particles, hair, and other debris, preventing them from entering the plumbing system.
  • Properly dispose of grease: Instead of pouring grease down the drain, cool it and dispose of it in the trash to avoid buildup in pipes.
  • Flush wisely: Only human waste and toilet paper should be flushed. Even items labeled as “flushable” can contribute to blockages.
  • Schedule septic maintenance: Regular inspections and pumping are essential to prevent solids from blocking the septic system.

By adhering to these preventative measures and maintenance tips, you significantly reduce the likelihood of sewer line blockages.
