Sewer Repair: Common Causes and Solutions

Sewer repair can be a daunting task for homeowners, but it is an essential one to ensure the proper functioning of the plumbing system. Sewer line damage can lead to sewage backups, slow drainage, and even potential health hazards. In this article, we will discuss the common causes of sewer line damage and the solutions available for homeowners.

Common Causes of Sewer Line Damage

Tree Roots – Tree roots can grow into sewer lines, causing blockages and damaging the pipes. This is particularly common in older homes with clay pipes, which are more susceptible to root infiltration.

Aging Pipes – Sewer lines, like all plumbing components, have a lifespan. Over time, pipes can become corroded, cracked, or collapsed, leading to leaks and blockages.

Improper Use of Plumbing Systems – Sewer lines are designed to handle human waste and toilet paper. However, flushing items such as paper towels, feminine hygiene products, or wipes can cause blockages and damage to the pipes.

Solutions for Sewer Line Damage

Trenchless Sewer Repair – Trenchless sewer repair is a less invasive alternative to traditional sewer repair. Instead of digging up the entire yard, only small access holes are required to repair the damaged section of the sewer line. This method is often faster and less expensive than traditional sewer repair methods.

Pipe Lining – Pipe lining involves inserting a new lining inside the damaged pipe. The lining is then inflated and cured in place, creating a new pipe inside the existing damaged pipe. This method can be used to repair pipes that have minor cracks or leaks.

Pipe Bursting – Pipe bursting involves breaking apart the damaged pipe and pulling a new pipe into place. This method is often used when a pipe is severely damaged or collapsed. It is a more invasive method but can be an effective solution for more serious damage.

How to Prevent Sewer Line Damage

Watch What You Flush – To prevent damage to your sewer lines, avoid flushing anything other than human waste and toilet paper down the toilet.

Regular Maintenance – Scheduling regular plumbing maintenance, including sewer line inspections, can help catch any potential issues before they turn into serious problems.

Plant Trees Away from Sewer Lines – If you have trees on your property, make sure to plant them away from sewer lines to prevent root infiltration.


Sewer repair can be a daunting task, but it is essential to maintain the proper functioning of your plumbing system. By understanding the common causes of sewer line damage, the available solutions, and preventative measures, homeowners can take proactive steps to protect their homes from the potential hazards of sewer line damage. Contact a licensed plumbing professional for assistance with any sewer line issues.
