Locate and repair - damaged pipe section
AFTER
BEFOREThe Problem
The property owner was experiencing recurring blocked drains and slow wastewater flow caused by a compressed section of underground sewer pipe. The restriction was preventing wastewater from flowing freely, resulting in repeated blockages and increasing the risk of sewage backing up into the property.
Using a professional CCTV drain inspection camera, our technician identified the exact location of the problem. The inspection revealed that a section of the drain had become compressed, significantly reducing the pipe's internal diameter and restricting the flow of wastewater and debris.
Left unrepaired, the damaged pipe would continue to cause recurring blockages, increase the likelihood of further structural failure, and potentially require more extensive and costly repairs in the future. Early detection with CCTV allowed the issue to be accurately diagnosed and a targeted repair solution to be carried out.
The Solution
After locating the damaged section with our CCTV drain inspection equipment, our technician carefully excavated the affected area to expose the compressed sewer pipe. The damaged section was removed and replaced with new PVC pipe, restoring the drain to its original diameter and ensuring unrestricted wastewater flow.
Once the repair was completed, the pipeline was reassembled using new fittings and tested to confirm all joints were watertight. A final CCTV drain inspection was then carried out to verify that the repaired section was correctly aligned, free from defects, and flowing as designed.
By replacing the compressed section rather than repeatedly clearing the symptoms, the customer received a permanent solution that eliminated the cause of the recurring blockages. The repaired drain is now operating efficiently, reducing the risk of future drainage issues and extending the lifespan of the underground pipework.
Equipment Used
To accurately locate and permanently repair the damaged drain, our technician used professional plumbing and drain inspection equipment. CCTV Drain Inspection Camera – Used to inspect the sewer line, locate the compressed section of pipe, and confirm the cause of the recurring blockage. Electronic Pipe Locator – Used to pinpoint the exact location and depth of the damaged pipe before excavation, minimising disruption to the property. Excavation Equipment – Used to safely expose the affected section of underground drain for repair. PVC Drainage Pipe & Fittings – New DWV (Drain, Waste and Vent) pipe and fittings installed to replace the compressed section and restore full pipe capacity. Pipe Cutting & Installation Tools – Professional tools used to remove the damaged pipe and install the replacement section accurately. CCTV Verification Camera – A final inspection confirmed the repair was correctly completed, the pipe was aligned, and wastewater was flowing freely. Using specialised equipment allowed DrainSpy Brisbane to accurately diagnose the problem, minimise excavation, complete a high-quality repair, and verify the drain was fully restored before the job was completed.
The Outcome
The damaged section of compressed sewer pipe was successfully located, excavated and replaced, restoring the drainage system to full working order. Following the repair, wastewater flowed freely through the new pipework with no restrictions or signs of recurring blockages.
A final CCTV drain inspection confirmed the repair had been completed to a high standard, with the new pipe correctly aligned and free from defects. The customer was provided with a long-term solution rather than a temporary fix, reducing the risk of future drainage issues and costly emergency repairs.
With the damaged pipe permanently repaired and the drainage system fully operational, the customer now has confidence that their sewer line is functioning efficiently and is protected against ongoing blockages caused by the previous pipe failure.
