A sewer backup occurs when the flow of wastewater is blocked or interrupted, causing sewage to reverse its course and flow back into homes or other structures. Several factors can contribute to sewer backups, and identifying the cause is crucial for preventing and addressing these issues. Common causes of sewer backups include:

1. Clogs in the Sewer Line:

   • Accumulation of debris, grease, tree roots, and other materials can create blockages in the sewer line, hindering the normal flow of wastewater.

2. Tree Roots:

   • Tree roots seeking moisture can infiltrate sewer pipes through cracks or joints. As roots grow and multiply, they can cause significant blockages and damage to the pipes.

3. Collapsed or Damaged Sewer Pipes:

   • Older sewer lines made of materials like clay or Orangeburg (a type of bituminized fiber pipe) can deteriorate, collapse, or become damaged over time, leading to obstructions.

4. Inadequate Pipe Slope:

   • Sewer pipes are designed with a slight slope to facilitate the flow of wastewater. If the slope is inadequate, water and waste may not drain properly, leading to backups.

5. Grease Accumulation:

   • Pouring grease or fats down drains can result in the buildup of sticky deposits in the sewer pipes, causing blockages and restricting the flow of wastewater.

6. Flushing Non-Flushable Items:

   • Flushing non-flushable items like wipes, sanitary products, paper towels, and other debris down toilets can contribute to sewer line clogs.

7. Combined Sewer Systems:

   • In areas with combined sewer systems (where stormwater and wastewater share the same pipes), heavy rainfall or storm events can overwhelm the system, leading to backups.

8. City Sewer System Issues:

   • Blockages or issues in the municipal sewer system, which are beyond the homeowner’s control, can cause backups. This may include problems with the main sewer line or sewage treatment facility.

9. Backflow from the Main Sewer Line:

   • In some cases, backflow from the main sewer line can occur due to increased pressure, pushing sewage back into individual properties.

10. Improperly Installed Sewer Pipes:

    • Poor installation practices, including improper alignment, incorrect pipe slope, or inadequate support, can contribute to sewer line issues and backups.

Preventing sewer backups involves a combination of regular maintenance, proper waste disposal practices, and prompt attention to warning signs. Homeowners can take measures such as installing backflow prevention devices, avoiding flushing inappropriate items, and scheduling regular sewer line inspections to identify and address potential issues before they escalate. If a sewer backup occurs, it’s crucial to seek professional assistance promptly to assess and resolve the problem.

The frequency of sewer inspections depends on several factors, including the age of your home, the type of plumbing system, and any previous issues you may have encountered. Here are some general guidelines for scheduling sewer inspections:

1. New Homes:

   • For newly constructed homes, it’s advisable to schedule an initial sewer inspection within the first few years, especially if you’re the first owner. This can help identify any potential issues early on.

2. Older Homes:

   • Older homes with aging sewer systems may benefit from more frequent inspections. As pipes age, they are more susceptible to problems such as corrosion, root intrusion, and deterioration.

3. Previous Issues:

   • If you’ve experienced sewer-related problems in the past, such as backups, slow drainage, or plumbing repairs, consider more frequent inspections. This helps catch potential issues before they escalate.

4. Every 5-10 Years:

   • As a general guideline, homeowners without significant plumbing issues may consider scheduling sewer inspections every 5 to 10 years. This regular interval allows for proactive maintenance and early detection of potential problems.

5. Before Home Purchase:

   • If you’re purchasing a new home, including a sewer inspection as part of the pre-purchase inspection process is a wise decision. This can reveal any existing issues with the sewer system.

6. After Storms or Flooding:

   • Following heavy rainfall, storms, or flooding, it’s a good idea to schedule a sewer inspection. Excessive water can overwhelm the sewer system, leading to backups or damage.

7. Change of Season:

   • Consider scheduling sewer inspections during seasonal changes, especially if you live in an area with extreme temperature variations. Freezing and thawing cycles can impact pipes.

8. Tree-Lined Properties:

   • If your property has mature trees, especially those with aggressive root systems, more frequent inspections may be necessary to check for root intrusion.

9. Preventive Maintenance:

   • Some homeowners choose to incorporate sewer inspections as part of preventive maintenance plans, especially if they have a history of sewer issues.

10. Signs of Trouble:

    • If you notice warning signs of sewer problems, such as foul odors, slow drainage, or unusual sounds, schedule an inspection promptly. Early detection can prevent more extensive damage.

It’s important to note that these are general recommendations, and the specific needs of your plumbing system may vary. Consulting with a licensed plumber can provide personalized advice based on your home’s unique circumstances. Regular sewer inspections can help catch potential issues early, prevent major problems, and extend the lifespan of your sewer system.

Hydro-jetting, when performed by trained professionals, is generally considered safe for sewer pipes. It is a powerful and effective method for cleaning and clearing blockages from sewer lines. However, there are important considerations to keep in mind:

1. Professional Expertise:

   • Hydro-jetting should be carried out by experienced and licensed plumbing professionals. They have the knowledge and training to use the equipment safely and effectively.

2. Appropriate Pressure Settings:

   • The pressure of the water used in hydro-jetting can be adjusted based on the specific needs of the plumbing system. Professionals will choose the appropriate pressure settings to avoid causing damage to the pipes.

3. Suitability for Different Pipes:

   • Hydro-jetting is generally suitable for various types of pipes, including PVC, cast iron, and clay. However, the specific condition and material of your pipes will be considered to ensure that hydro-jetting is the right choice.

4. Inspection Before Hydro-Jetting:

   • Before performing hydro-jetting, it’s common for plumbers to conduct a camera inspection of the sewer lines. This allows them to assess the condition of the pipes, identify any potential issues, and determine the most suitable approach.

5. Avoiding Old or Damaged Pipes:

   • In some cases, very old or severely damaged pipes may not be suitable for hydro-jetting. The water pressure could exacerbate existing issues. In such cases, alternative methods or repairs may be recommended.

6. Environmental Considerations:

   • Hydro-jetting uses water pressure rather than chemicals, making it an environmentally friendly option for cleaning sewer lines. It doesn’t introduce potentially harmful substances into the sewer system.

7. Preventing Future Issues:

   • Hydro-jetting not only clears existing blockages but also removes accumulated debris, grease, and mineral deposits from the pipe walls. This can help prevent future clogs and maintain the flow of wastewater.

While hydro-jetting is generally safe and effective, it’s crucial to rely on qualified professionals for this service. Attempting to use high-pressure water jetting equipment without the necessary expertise can lead to damage to the pipes and other plumbing components.

If you’re experiencing sewer line issues or are considering preventive maintenance, consult with a licensed plumber. They can assess the condition of your sewer pipes, recommend the most appropriate solutions, and determine whether hydro-jetting is a suitable option for your specific situation.
