12 Common Problems Detected During Sewer Inspection

Cracked or broken pipes are one of the most common challenges detected during sewer inspections. These structural issues often stem from natural wear and tear over time, compounded by environmental factors like ground movements or extreme weather conditions. Ageing pipelines can develop fractures that compromise their integrity, allowing wastewater to leak into the surrounding soil. This can escalate quickly, leading to significant water loss and soil erosion, which could damage the foundation of buildings. Detecting these fractures early is crucial, and regular sewer camera inspections can help identify them before they escalate into more serious problems.

Moreover, soil erosion due to leaking pipes can cause the ground to become unstable, presenting risks to the structural stability of nearby constructions. Therefore, early detection and repair of cracked pipes not only saves on potential repair costs but also prevents possible safety hazards. Materials like cast iron are particularly vulnerable to cracks over extended periods. Proactive maintenance strategies, such as routine inspections, can help mitigate these risks and prolong the lifetime of sewer systems.

2. Tree Root Intrusion

Roots from nearby trees can penetrate sewer pipes, leading to significant blockages and damage over time. These roots naturally seek water and nutrients, and sewer pipes provide an ideal environment. Particularly common with older pipes made of clay or cast iron, root intrusions can cause significant structural damage if not addressed promptly. Regular sewer inspections can help detect early signs of tree root intrusion, allowing for timely repair and prevention of further damage.

The impact of root intrusion is not merely limited to blockages; it can also lead to physical damage as roots expand within the pipes, exacerbating leaks and even resulting in complete pipe collapse. Some effective solutions include using chemical root removal methods or hiring professionals to perform root cutting and pipe repair. Upgrading to PVC piping, which has better resistance to root penetration, can also be a strategic long-term solution.

Ignoring this issue can lead to severe backups, causing overflows and potential sanitation concerns. Taking preventive measures and investing in regular inspections can save homeowners from future headaches and costly repairs.

3. Sediment and Debris Build-up

Over time, sediment and debris can accumulate inside sewer pipes, leading to potential clogs that restrict flow. This buildup can be composed of various materials like sand, silt, leaves, and general waste products that manage to get through household drains. When left unchecked, these materials can lead to significant blockages, causing backups and sanitation issues. Regular cleaning, alongside inspections, helps in identifying areas where debris accumulation is prevalent, enabling timely clearing to prevent more severe clogs.

4. Corrosion of Pipes

Corrosion is another common problem that can be detected during sewer inspections, especially in older metallic pipes such as those made from iron or steel. Corrosion weakens the pipe walls, leading to leaks and potential water contamination. As pipes age, they are more susceptible to rust and other forms of corrosion, which can severely compromise the integrity of the system. Effective maintenance includes replacing outdated pipes with corrosion-resistant materials, like PVC, that can enhance the longevity of the sewer system.

5. Bellied Pipes

A bellied pipe, also known as a sag, occurs when a section of pipe sinks, creating a low point where waste and debris can gather. This can reduce the efficiency of wastewater flow, leading to frequent blockages. Identifying a bellied pipe requires a detailed inspection, and once detected, solutions often involve realigning or replacing the affected section to restore proper flow.

Ignoring bellied pipes can result in persistent sewer backups and more frequent maintenance needs, increasing costs over time. By ensuring pipes have the correct alignment and addressing any underlying soil issues, you can prevent these sags and maintain a healthy sewage flow.

6. Leaks and Water Seepage

Water leaks in the sewer lines are a crucial issue that can cause erosion, sinkholes, and even structural damage if not promptly managed. Seepage often occurs at pipe joints or where pipes have sustained damage, and it can lead to wastewater escaping into the surrounding environment, polluting soil and waterways. Regular inspections can detect leaks early, allowing for immediate intervention to replace or repair the affected areas, thereby avoiding substantial environmental and property damage.

7. Collapsed Sewer Lines

A severely neglected sewer line can ultimately collapse, leading to substantial blockages and disruptions in the system. Collapses often result from prolonged root intrusion, persistent blockages, or material fatigue over time. Collapsed lines can potentially cause catastrophic failures, leading to backups into homes and properties, necessitating immediate repair or full replacement of the affected segments.

8. Inadequate Pipe Slope

Proper pipe slope is essential for efficient sewage flow. When pipes are incorrectly sloped, it can result in sluggish drainage and frequent blockages due to accumulated waste material. Adjusting the slope can require significant work, but it’s crucial for ensuring sewage moves freely through the system without unnecessary backups.

9. Misaligned Pipes

Pipes may become misaligned due to natural ground movements, improper installation, or external pressure. Misalignment can create sections where waste accumulates, leading to potential blockages. Identifying and correcting this issue involves precise inspections and realignment or replacement of affected sections to restore optimal functionality.

10. Older Pipe Material

Older sewer systems often comprise materials that are no longer considered optimal for long-term durability, such as clay or cast iron. These materials are prone to issues like corrosion, cracking, and root intrusion. Upgrading these older systems to modern alternatives like PVC can greatly enhance the reliability and lifespan of the sewer system.

11. Obstructive Grease Buildup

Grease is a common problem for household plumbing, particularly when it cools and hardens inside pipes. Over time, layers of grease buildup can obstruct sewer lines, causing severe clogs. Regular flushing and inspections help spot potential grease accumulation points, keeping your sewage system running smoothly and efficiently.

12. Fluctuating Water Pressure

Inconsistent water pressure can be a sign of underlying blockages or leaks within the sewer system. These fluctuations often suggest something is amiss, such as pipe constrictions due to sediment buildup or minor fractures. Regular checks can diagnose these underlying issues, allowing for targeted repairs and maintaining consistent pressure throughout the plumbing system.
