Basin Mixer Replacement and Kitchen Tap Repair Completed in Richmond
Completed Job Summary
Leaking basin and kitchen taps were identified during a residential plumbing job in Richmond on 4 March 2026. Pressure was checked, a basin mixer was replaced, kitchen taps were serviced, and a new top half set was installed after servicing.

Customer report
The customer reported multiple leaking taps within the property and requested that water pressure be checked during the visit. The basin tap was leaking consistently, and the kitchen tap set was also leaking during normal operation. During attendance, pressure was identified as slightly elevated. Multiple options were discussed on site, and the customer chose to proceed with replacing the basin mixer and addressing the kitchen tap leaks, without proceeding with pressure limiting valve installation at that time.
Diagnosis & Technical Assessment
Technician Jayden attended a Richmond property to assess reported leaking taps and review system pressure conditions. Pressure readings were identified as slightly elevated, which can influence wear rates across internal tap components. The basin mixer and kitchen tap set were assessed separately due to differing configurations and failure behaviour.
The basin mixer was identified as requiring replacement based on its condition and leakage profile. The kitchen tap set was assessed for restoration using a service-based approach. This involved isolating the water supply, draining residual water, and preparing the taps for disassembly. Internal components, such as o-rings, fibre washers, and tap washers, were identified as serviceable and restored under standard procedures.
Following disassembly and servicing, (including machining the tap seat, flushing debris, lubricating moving parts, and reassembly) the kitchen tap set was tested under pressure. The leak persisted after servicing, indicating that wear within the tap assembly exceeded what could be corrected solely by component replacement. Based on this outcome, the repair pathway was revised to include installation of a new top half set. Final testing confirmed that both the basin and kitchen tap leaks were resolved.
All work was completed in accordance with the Victorian Building Authority (VBA) regulatory framework.
Solutions delivered
Work was completed at both affected tap locations using a staged repair-and-replacement approach. The basin mixer was isolated, removed, and replaced with a new unit, followed by reconnection and functional testing. For the kitchen taps, a restoration-first approach was implemented in line with standard repair procedures and cost-optimised for a full tap service.
When servicing did not resolve the leak, the technician reassessed the condition of the tap assembly and proceeded with the installation of a new top half set. This decision was based on the observed condition of internal components and the inability of servicing to achieve a stable seal. This approach ensured that unnecessary full replacement was avoided until performance testing confirmed the need for component replacement.
Tools, Parts & Systems Used
- Basin mixer
- Top half set
- O-rings
- Fibre washers
- Tap washers
Outcome & Results
The basin mixer replacement and kitchen tap rectification were completed during the same visit, with both systems tested after installation. The final outcome was a leak-free basin mixer and the resolution of kitchen tap leaks following the installation of the new top half set. Pressure limiting valve work was discussed but not undertaken during this job, with the completed scope focused on resolving the identified tap failures.
All work was carried out in accordance with relevant Australian Standards and safety requirements.
Repair vs Replacement
This job demonstrates the decision boundary between tap servicing and component replacement. Servicing can restore function when internal components, such as washers and seals, are the primary failure points and the tap body remains serviceable. In this case, servicing was initially applied to the kitchen taps, but did not resolve the leak. This indicated that internal wear extended beyond replaceable service components. Replacing the top half set yielded a more reliable outcome. A repair-first approach can reduce unnecessary replacement, but testing after servicing is required to confirm whether further intervention is needed.
