Performing a CCTV pipe inspection is an essential process for identifying obstructions and diagnosing issues within plumbing systems. This guide provides a step-by-step approach to ensure accurate and efficient inspections, helping technicians and homeowners maintain healthy pipelines.

Preparation Before the Inspection

Before starting the inspection, gather all necessary equipment, including a CCTV camera, a suitable inspection rod, and safety gear. Ensure the camera is clean and in working condition. Obtain relevant pipe maps or diagrams to understand the layout of the plumbing system. Clear the area around access points to facilitate easy entry and exit during the process.

Inspecting the Access Point

Locate the access point, such as a cleanout or inspection chamber. Remove any covers carefully and check for blockages or damages that might hinder camera insertion. Ensure the access point is stable and safe for equipment operation.

Inserting the CCTV Camera

Insert the CCTV camera into the pipe slowly, maintaining a steady pace. Use the inspection rod to guide the camera through the pipe. Monitor the live feed on the display to navigate and observe the pipe interior. Move the camera at a controlled speed to capture clear images of the pipe walls.

Identifying Obstructions and Issues

As the camera advances, look for signs of obstructions such as blockages, cracks, or root intrusions. Pay attention to:

  • Blockages: buildup of debris, grease, or foreign objects.
  • Cracks and fractures: potential points of failure or leaks.
  • Root intrusions: tree roots invading the pipe interior.

Document any issues by taking screenshots or recording videos for later analysis. Note the location and severity of each problem for planning repairs or cleaning.

Completing the Inspection

Once the inspection is complete, carefully withdraw the camera from the pipe. Clean the camera and equipment before storage. Replace the access point cover securely. Review the footage to prepare a report or to discuss necessary repairs with clients or team members.

Safety Tips and Best Practices

Always wear appropriate safety gear, including gloves and eye protection. Work in well-ventilated areas and ensure the equipment is properly grounded. Follow manufacturer instructions for all tools and devices used during the inspection. Regularly maintain and calibrate equipment to ensure accurate results.
