Issue: Blocked Stack Pipe
Report:
Attended site to investigate a reported blockage in the stack pipe.
Access was created into the external stack pipe serving Flats 20A and 20B. A CCTV inspection was carried out; however, visibility was limited due to waste water being held within the stack pipework.
It was observed that whenever Flat 20A discharged water or flushed the toilet, waste water would back surge into Flat 20B. This resulted in sewage flooding within Flat 20B, contaminating the carpets and saturating the bathroom flooring.
A chain machine was deployed to mechanically clear the blockage, during which a large quantity of baby wipes was recovered.
The stack pipe was traced to a manhole located on the ground floor. A further CCTV inspection from this point revealed fractured pipework within the system, which was contributing to the blockage.
A high-pressure water jetting unit was then set up. Once the water tank was filled, the pipeline was jet blasted to remove the obstruction. During this process, two large cracked sections of pipe were successfully dislodged and recovered from within the 4-inch pipeline.
A final CCTV inspection confirmed that the entire line was now clear and flowing freely.
