Plumbers often conduct video inspections of sewer lines to help them identify, locate, and address potential problems. This process involves using specialized cameras to explore the plumbing systems. Learn what to expect during a video inspection of a sewer line to prepare for the process.
Preparation
Before a video inspection of a sewer line, the plumber first looks for access points, such as cleanouts or drains, to insert the camera. They may need to clear away any debris around these access points to ensure smooth entry for the inspection equipment. Additionally, the plumber will gather information about the property’s layout and plumbing history to anticipate potential problem areas.
In some cases, the plumber will need to clear drains to allow the camera to pass through, but this clearing process does not mean the drains will be perfectly cleaned out. The primary goal is to remove enough obstructions to make the inspection possible. This preparation helps ensure a thorough and accurate video inspection of the sewer line.
The Inspection Process
The inspection begins with the insertion of a waterproof camera attached to a flexible rod into an access point of the sewer line. This camera transmits real-time video footage to a monitor, allowing the plumber to examine the inside of the pipes. By navigating through the line’s bends and curves, the camera provides insights that would otherwise be impossible to achieve without excavation.
The plumber then meticulously scrutinizes the footage, looking for signs of damage or unusual wear within the sewer line. They take note of any cracks, corrosion, or misalignments that could indicate a failing system. This detailed examination helps pinpoint issues that may require more attention.
Common Issues Found
As the property owner, you can expect a video inspection to reveal blockages caused by foreign objects, grease buildup, or non-flushable materials in the sewer line. These obstructions can lead to slow drains and backups if not addressed promptly. After identifying the source of the blockage, the plumber can recommend targeted solutions, such as snaking, to restore normal flow.
Root intrusions are another common issue found during inspections, particularly in older properties with mature landscaping. Hiring licensed sewer contractors ensures that repairs and restorations are conducted in strict compliance with local regulations, minimizing the risk of future liabilities.
Possible Leaks Require Follow-Ups
A camera inspection won’t be enough to locate a leak in a sewer line because the camera can only capture the interior of the pipe. Thick-walled pipes can have surface irregularities that appear to be cracks, but they may not penetrate the entire pipe. Additional diagnostic tools, such as pressure tests or dye tests, may be necessary to confirm the presence of a leak. Another issue is that the plumber must interpret what they see on the monitor, and years of buildup inside the pipe can obscure potential leaks.
Video inspections of sewer lines offer a beneficial way to locate and diagnose plumbing issues with minimal disruption. The process allows plumbers to identify blockages, corrosion, and root intrusions effectively so they can then recommend appropriate solutions. In some cases, the footage may suggest that follow-up tests are needed for an accurate assessment of the plumbing system.
