Customer report
The customer reported hearing dripping sounds coming from the dishwasher area and requested an investigation of a possible leak. The request also included checking water pressure and inspecting the pipework beneath the sink. The concern centred on potential leakage from the dishwasher and surrounding plumbing components in the kitchen area.
Diagnosis & Technical Assessment
Inspection was carried out across the dishwasher area and the basin waste assembly beneath the sink. During assessment, attention was directed to the basin waste components due to their proximity to the reported sound source and visible connection to the drainage system.
The existing basin waste trap was identified as a component requiring replacement based on its condition and suitability within the current setup. The dishwasher was also observed during inspection, with its condition noted as part of the broader assessment of the area.
The evaluation focused on isolating potential leak points within accessible plumbing connections and identifying components that could contribute to intermittent dripping sounds. The basin waste trap formed a key part of this inspection due to its role in drainage flow and sealing.
Observations supported proceeding with the replacement of the basin waste trap to address the identified issue within the system.
All work was completed in accordance with the Victorian Building Authority (VBA) regulatory framework.
Solutions delivered
The existing basin waste trap was removed during the rectification process. A new 40mm combo S+P trap was installed to replace the previous component and restore proper drainage configuration under the sink.
The selection of the replacement trap aligned with the existing basin waste setup, ensuring compatibility with pipework and maintaining appropriate flow and sealing within the system. The installation addressed the identified issue associated with the previous trap and improved the integrity of the waste connection.
Following installation, the work area was cleaned to restore the site to its original condition. The completed work focused on resolving the basin waste component within the broader context of the reported issue in the kitchen area.

Outcome & Results
The basin waste trap was successfully replaced, restoring the functionality of the sink drainage system. The updated component provides a stable and properly configured connection within the basin waste assembly.
The work completed addressed the identified issue within the accessible plumbing system. The area was left clean following completion, and the basin waste system was returned to operational condition.
All work was completed in accordance with the Victorian Building Authority (VBA) regulatory framework.
Repair vs Replacement
In this scenario, replacement of the basin waste trap was selected due to the condition and suitability of the existing component within the drainage system. Waste traps play a critical role in maintaining proper flow and sealing, and when a component no longer meets functional requirements, replacement ensures system integrity.
Repair is typically considered when fittings remain structurally sound and can be restored through adjustment or minor component changes. However, when a trap is inadequate or compromised, full replacement provides a more reliable outcome and reduces the likelihood of recurring issues within the waste system.
