Completed Job Summary
A leaking shower at a residential property in Fitzroy North was investigated following reports that the leak was likely originating from the cold water tap. Assessment during the repair identified a deteriorated in-wall breech, which was replaced along with new recessed tap tops and a 20 mm boundary pressure-limiting valve before the plumbing system was tested.

Customer report
The customer requested plumbing assistance after noticing a leaking shower and believed the leak was likely caused by the cold-water tap. The property had not previously been serviced by Zebra Plumbing. Once the existing tap assemblies were removed during the repair, the in-wall breech was found to require replacement, necessitating additional plumbing work beyond the original expectations.
Diagnosis & Technical Assessment
The initial customer report suggested the shower leak was likely caused by the cold water tap. During the repair process, the existing hot and cold tap assemblies were removed to assess the concealed plumbing components. This inspection found that the in-wall breech had deteriorated to the point where replacement was required rather than retaining the existing fitting.
The repair scope was expanded to include replacing the in-wall breech, along with new recessed tap tops. A 20 mm boundary pressure-limiting valve was also installed as part of the completed works, in accordance with the requirements of AS/NZS 3500 Part 1, to control the maximum static water pressure within the property. Following installation, the plumbing system was reinstated and tested to confirm normal operation after the repairs were completed.
All work was completed in accordance with the Victorian Building Authority (VBA) regulatory framework.
Solutions delivered
The water supply was isolated before the existing shower tap components were removed. Replacement hot and cold recessed tap tops were installed, followed by the removal of the deteriorated in-wall breech. A new breech assembly was fitted, pipework was reconnected, and the plumbing installation reinstated.
A new 20 mm boundary pressure limiting valve was also installed to regulate incoming water pressure in accordance with AS/NZS 3500 Part 1. Once all replacement components had been installed, the water supply was restored and the plumbing system tested. The technician recorded that the work proceeded smoothly and the shower plumbing was returned to service following completion.

- Shower plumbing system
Outcome & Results
The leaking shower was repaired by replacing the deteriorated in-wall breech, installing new recessed tap tops, and installing a boundary pressure-limiting valve. Following completion, the plumbing system was tested and returned to normal operation. The completed work also introduced pressure control measures designed to limit excessive static water pressure in accordance with the specified installation requirements.
All work was carried out in accordance with relevant Australian Standards and safety requirements.
Repair vs Replacement
Minor shower leaks can sometimes be resolved by replacing serviceable tap components. Where concealed plumbing components, such as an in-wall breech, are found to have significantly deteriorated during repair, replacement may be the most appropriate long-term solution. In this completed job, the observed condition of the existing breech necessitated its replacement, along with the installation of new tap tops and a pressure-limiting valve to restore the plumbing system.
