Understanding sewer line problems

If you know the various types of sewer damage, it'll be easier to recognize them when they occur and find the ideal sewer repair and replacement method. Here are some of the most common types:


  • Tree root infiltration or ingress: Tree roots can penetrate and grow inside sewer lines, especially if the pipes have small cracks or joints.  

  • Corrosion: Older sewer pipes, particularly those made of cast iron or clay, are susceptible to corrosion over time.  

  • Blockages: Blockages can occur due to the accumulation of grease, debris, hair, soap scum, and non-flushable items like wet wipes and sanitary products.

  • Cracks and leaks: Pipes can develop cracks for various reasons, including ground shifts, temperature changes, or external pressure from heavy machinery.  

  • Offset pipes: Offset pipes occur when two pipe sections become disconnected or misaligned. This can create gaps or steps within the sewer line, obstructing the flow of wastewater and causing blockages.


Meanwhile, natural elements such as shifting soil, heavy rainfall, or freezing and thawing cycles can impact sewer lines. The age of the infrastructure also makes it prone to deterioration over time. Understanding the different types of sewer line damages or problems allows you to proactively maintain your systems and find the best solutions.



Signs of sewer line damage

Recognizing the tell-tale signs of sewer line damage can prevent them from worsening and becoming more costly. Here are some common indicators of potential sewer line issues:

  • Slow drains: If several drains in your home are malfunctioning, there could be a blockage in the main line.

  • Foul odours: Unpleasant smells around your home or yard often indicate sewer line issues.

  • Lush patches in the yard: Greener, lusher areas in your yard might suggest a leaking sewer line underground.

  • Sewage backups: The most obvious sign, sewage backing up into your home, indicates a severe issue.


If you notice any of these indicators and think you need help, it's best to consult a professional plumber for a thorough inspection and appropriate repairs.


How to repair a damaged sewer line

Repairing a damaged sewer line can be simple or complex, but understanding the steps involved can help you manage the process effectively. Here's a detailed guide on how to repair a damaged sewer line:


Step 1: Inspection

Check for signs like slow drains, sewage backups, and foul odours. If you hire professional plumbers, they can use a sewer camera to find the damage and determine its severity.


Step 2: Decide on repair or replacement

Depending on the severity of the damage, you can either repair a section of the pipe or replace the entire line. Spot repairs might be sufficient for minor issues like small cracks or tree root infiltration. For more extensive damage, sewer replacement may be necessary.


Step 3: Gathering materials and tools

Here's a quick list of some of the materials and tools you'll need for your repair project:

  • Pipe repair kits or replacement pipes

  • Sewer line couplings

  • Shovels and digging equipment

  • Safety gear (gloves, goggles, etc.)


Besides the above, you may also need a utility knife, a pipe cutter and measurement aids. This list might expand depending on the extent of the damage you want to fix.


Step 4: Digging up the damaged area

Carefully scoop the area around the damaged section of the sewer line. Do this slowly but surely to avoid further damaging the pipe or any surrounding utilities.


Step 5: Repairing the sewer line

Use a pipe repair kit to seal small cracks or holes. For larger sections, you may need to cut out the damaged portion and replace it with new pipe segments. Ensure all connections are secure and leak-free.


Step 6: Testing the repair

Once you finish the repair, run water through your plumbing system and check for any signs of leakage at the repair site.


Step 7: Refilling the excavated area

Did your repair turn out well? Then, it's time to refill the trench with the excavated soil. Compact the soil firmly to prevent any settling or shifting. Repairing a damaged sewer line involves careful inspection, appropriate repair methods, and diligent testing. By following these steps, you can complete a DIY sewer line repair project efficiently.


Conclusion

Knowing how to repair a sewer line might seem like out of your skills arsenal, but you can think of it as an advantage as it can save you so much time, effort, and money in an emergency. However, you must also know when to call professionals to effectively contain the damage and ensure the job is done correctly. Following this guide, you can care for your sewer system and avoid costly consequences.
