Drain Flow Restored at a South Yarra Property
Completed Job Summary
A blocked toilet and bath drain was attended to at a residential property in South Yarra. Access constraints beneath the building changed the approach, leading to toilet disconnection, jetting from multiple points, identification of root ingress, and partial clearing that restored wastewater flow.

Customer report
The customer reported a blocked toilet and shower or bath at the South Yarra property. Initial job intake noted that the pipework ran under the floor and that access was through a locked door. A basement jetting option was considered first, depending on whether access could be obtained, as this would avoid disconnecting the toilet and working back through the affected fixtures.
Diagnosis & Technical Assessment
The job was attended to investigate blocked drainage affecting the toilet and bath. Inspection openings were sought in the garage below to access the line from below, but the area was heavily packed with stored items and was not the tenant’s garage, limiting practical access to the manhole. Based on those site conditions, the work proceeded through the toilet connection instead.
The toilet was disconnected so jetting could be carried out through the toilet branch. Initial jetting from that point did not clear the blockage effectively, so a further attempt was made from the BT side. During that process, multiple root ingress points were identified within the drain line. Some root material was cleared from that side, and a further jetting attempt through the toilet branch then opened enough of a pathway for wastewater flow to return.
The technical outcome confirmed that root ingress was contributing to the blockage. The line was improved sufficiently to restore function, but the roots were not completely cleared, and the drain was not fully restored to a clean condition.
All work was completed in accordance with the Victorian Building Authority (VBA) regulatory framework.
Solutions delivered
The solution delivered on site was shaped by the access limitations underneath the property. Because practical access to the garage manhole could not be obtained, the toilet was disconnected and reconnected to allow jetting equipment to be used through the toilet branch. Byron attended to assist with the jetting process, and clearing attempts were made from multiple entry points to improve the result.
The toilet branch was jetted first, followed by a second clearing attempt from the BT side after the initial pass did not work well enough. Once the root ingress was located, additional clearing was performed to remove part of the obstruction. A final pass through the toilet branch restored a sufficient pathway for flow.
As the blockage source extended beyond a simple isolated obstruction, a further quote was prepared for excavation and renewal of the blocked and cracked drain, to be passed to the body corporate for next-stage works.

Outcome & Results
Wastewater flow was restored at the property after partial clearing of the blocked line. The work re-opened enough of the drain path for function to return, but root ingress remained in the line, and the blockage was not completely cleared. A further quote was prepared for the excavation and renewal of the blocked and cracked drain so the underlying condition could be addressed through body corporate-managed works.
All work was carried out in accordance with relevant Australian Standards and safety requirements.
Repair vs Replacement
For blocked drains affected by root ingress, repair and replacement decisions depend on whether flow can be restored and whether the pipe condition remains serviceable afterwards. In this job, jetting restored enough flow for the line to operate again, which supported a clearing approach on the day. Replacement became the next-stage recommendation once root ingress and a cracked drain condition were identified, as partial clearing did not remove the full obstruction. Where access is restricted and the line condition is deteriorated, clearing may restore short-term function while excavation and renewal address the underlying defect.
