Sewer and Water Pipe Repairs Completed in Malvern
Completed Job Summary
Sewer deterioration and a fractured copper water pipe were addressed during plumbing works in Malvern. Drain jetting and camera inspection identified dislodgement, roots, rust, and broken pipes, while the completed works included a new gully trap, an inspection opening, partial sewer renewal, and replacement of the fractured copper pipe and fittings.

Customer report
The Malvern work involved an existing sewer issue requiring further investigation and renewal, as well as a burst water pipe requiring location and repair. An earlier spot dig had been completed at a gully at the rear/side of the property. Further investigation in another gully revealed additional deterioration in the sewer, leading to an expanded drainage scope.
Diagnosis & Technical Assessment
Drain jetting and camera inspection were used to assess the sewer after the earlier gully work. Inspection identified further dislodgement and root intrusion through another gully. Technician observations also recorded rust and broken pipework within the drainage system. These physical conditions supported further sewer renewal rather than treating the work as an isolated gully repair.
A camera and locator were used to investigate the sewer alignment. The equipment could not properly establish the route, although the sewer appeared to continue towards the grassy area beside the house. The proposed approach, therefore, included excavation before the required sewer-renewal materials were ordered.
The water-pipe scope was investigated separately. Advanced leak detection formed part of the planned assessment, with the repair approach to be determined once the leak location and condition were established.
During the subsequent works, a fractured copper pipe was identified. Concrete cutting was undertaken to access and repair the leak, and the damaged copper pipe and associated fittings were removed.
All work was completed in accordance with the Victorian Building Authority (VBA) regulatory framework.
Solutions delivered
Initial drainage works included the installation of a new gully trap, the connection of the 50 mm waste to the ORG, and the installation of an inspection opening for future access. The drain was jetted and camera-inspected, with the resulting observations supporting the subsequent sewer-renewal scope.
The existing area was excavated, and partial in-ground sewer renewal was undertaken. Crushed rock was referenced as part of these works. The hot water service was also removed during access and excavation work.
The water leak required concrete cutting to reach the affected pipework. The fractured copper pipe and fittings were cut out and replaced with new copper pipe and fittings. A new external lever valve was also installed.
These works addressed the specifically identified damaged water pipe while the broader sewer-renewal works progressed separately.
Tools, Parts & Systems Used
- Drain jetting equipment
- Drain camera and locator
- Excavator / 1.8 machine
- Concrete cutter
- Gully trap and inspection opening
- Copper pipe, fittings and external lever valve
Outcome & Results
The recorded works resulted in the installation of a new gully trap and inspection opening, together with partial in-ground sewer renewal following the drain assessment. The fractured copper pipe and fittings were removed and replaced, and a new external lever valve was installed.
The sewer work remained within scope after the recorded 20 July activities, so the completed outcome shown here is limited to the specific installations, partial renewal, and water-pipe repair documented during the supplied work period.
All work was carried out in accordance with relevant Australian Standards and safety requirements.
Repair vs Replacement
Drainage defects can sometimes be addressed through clearing or localised repairs where the surrounding pipe remains serviceable. Where inspection identifies physical deterioration, such as displaced sections, root intrusion, rust, or broken pipework, renewal of the affected pipe may be necessary.
In this Malvern job, jetting and camera inspection identified multiple physical sewer defects, supporting a renewal scope beyond the earlier gully work. For the water leak, the fractured section of copper pipe and its fittings were removed and replaced rather than retaining the damaged section.
