Unexplained water consumption, pressure loss or recurring make-up water can disrupt a commercial or industrial site. Leak detection helps narrow down a suspected fault before repair work, excavation or demolition is considered. Find a Master Plumber to help assess concealed, underground and operational water-loss concerns across managed buildings and facilities.

When unexplained water loss needs closer attention
A visible leak is not the only reason to investigate. On commercial, industrial, strata and facility-managed sites, a suspected water loss may be concealed in pipework, below a slab, within a wall cavity, in a plant room or along an external service route. The practical aim of leak detection is to build a clearer picture of where a fault may be before repair work begins.
Commercial leak detection can relate to hidden leaks, underground leaks, pressure loss, service pipe faults, plantroom leaks, irrigation leaks, tank leaks and unexplained water consumption. The location and operating conditions matter: a fault in a ceiling space, riser, pump room, car park, landscaped area or tenancy can present very differently.
Signs that may prompt leak detection
Water loss is not necessarily obvious at the point where it occurs. A site team may instead notice a change in consumption, pressure or the condition of surrounding surfaces. These signs do not identify the cause on their own, but they can help explain why an investigation is warranted.
Abnormal water bills or unexplained meter movement
A drop in pressure or recurring pressure concerns
Water staining, damp flooring, mould or corrosion
Ponding in an external area
Hot or cold spots in an affected area
A pump that is running unexpectedly
Recurring make-up water demand
For industrial leak detection, it can also be useful to consider how a suspected fault relates to plant operation, access restrictions, process impacts and any available shutdown window. Clear site information supports a more focused conversation with a plumbing business.
How a leak investigation can narrow the location
There is no single method that suits every building or site. The approach may depend on the water supply layout, pipe material, asset age, pressure zones, known repairs, affected area and whether the suspected leak appears active all the time or only in certain conditions.
Commercial water leak detection may involve one or more of the following methods:
Acoustic testing to investigate sound associated with a suspected leak.
Water meter and consumption review to examine water-use patterns and meter behaviour.
Data logging to capture information over time.
Pressure testing as part of investigating pressure loss.
Hydrogen tracer gas testing where suitable for the investigation.
Pipe microphones inserted into drains or pipework.
Correlation testing using correlators.
Cable, conduit and service locating to help identify site services.
Thermal review, GPR or other subsurface scanning may also be considered where suitable before excavation. The purpose is not to promise a predetermined outcome; it is to use the available site evidence to narrow the likely fault location and inform the next decision.
Why site context matters on commercial and industrial properties
Leak detection on a managed site often involves more than identifying an affected area. Access arrangements, occupied spaces, plant locations, operational continuity and authority to approve further investigation can influence how the work is planned.
Facility managers, strata managers, business owners, asset managers and maintenance coordinators can make the initial enquiry more useful by identifying the relevant asset or location. Industrial operators and maintenance teams may also need to account for process impacts, safety permits, isolation requirements, environmental controls and critical production impacts.
Site consideration
Why it is useful
Plant or asset location
Helps direct attention to the relevant area, such as a plant room, riser, roof plant area or service corridor.
Meter readings and water bills
Can provide context for a change in consumption or meter movement.
Drawings, asset registers and past reports
May assist with understanding pipe routes, prior repairs and site history.
Access and shutdown arrangements
Helps the plumbing business understand operational restrictions before work is considered.
Prepare useful information before choosing a plumbing business
Good information does not replace investigation, but it can help a Master Plumber or plumbing business understand the concern and the site conditions. Gather what is readily available rather than delaying an enquiry to create a complete file.
Record the property address, contact person and practical access instructions.
Note the affected area, when the issue began and whether it is constant or intermittent.
Keep relevant photos, meter readings, water bills or short videos.
Identify whether hot water, cold water, pumps or a particular area appear to be involved.
Provide available site plans, hydraulic drawings, asset records, manuals and previous reports.
Flag access requirements, inductions, permitted working hours, shutdown windows and the person authorised to approve further investigation.
For industrial sites, include known isolation requirements, permits, confined-space risks, hot works requirements and environmental controls where relevant to the location or work being considered.
Choosing a Master Plumber for leak detection
When the source of water loss is uncertain, the most useful first conversation is usually specific: explain what has changed, where it has been observed, what site records exist and which operational limits apply. This helps you compare plumbing businesses based on the relevance of their response to your site and the investigation required.
Find a Master Plumber connects customers with Master Plumbers and plumbing businesses associated with the Master Plumbers and Gasfitters Association of Western Australia. Choosing a Master Plumber helps consumers make a more informed choice of plumbing business for their property or project.
The Association has represented Western Australia’s plumbing and gasfitting industry since 1901.

Equipment and suppliers customers may encounter
Names seen in quotes, equipment discussions or site records can vary with the investigation method and existing site assets. Examples customers may encounter include Sewerin, Gutermann, HWM, SebaKMT, Primayer, FCS, Fuji Tecom, Radiodetection and Vivax-Metrotech, along with supply channels such as Reece, Galvins, Tradelink, Parkwood Plumbing Centre, Bunnings and Plumbing Plus.
Other names associated with equipment and supply channels include Leica, IDS, GSSI, Mala, Hilti, Testo, Fluke, Rothenberger, RIDGID, Milwaukee and Subtronic. These are examples only; their presence does not determine the appropriate investigation for a particular site.
Related commercial and industrial plumbing services
A suspected leak can overlap with other systems. Where the evidence points beyond water-loss investigation, it may be useful to consider drainage, pumps and pumping equipment, storm water systems and drainage, roof plumbing or general plumbing. The right path depends on the affected asset and site conditions.
Drainage for drainage cleaning, repairs, CCTV services and related pipework concerns.
Commercial leak detection involves investigating suspected water loss, hidden leaks, pressure loss and concealed pipe faults in commercial, industrial, strata and facility-managed buildings. The aim is to narrow the potential fault location before excavation, demolition or repair work begins.
What signs can indicate a concealed water leak?
Possible signs include abnormal water bills, meter movement, pressure drop, damp surfaces, mould, ponding, corrosion, unexpected pump operation and recurring make-up water demand. These signs do not confirm the cause, but they can provide useful context for an investigation.
What methods may be used for leak detection?
Methods may include acoustic testing, meter and consumption review, data logging, pressure testing, hydrogen tracer gas testing, pipe microphones, correlation testing, and cable, conduit and service locating. The suitable approach depends on the site and suspected fault.
What should I provide when making an enquiry?
Useful details include the property address, affected location, photos, meter readings, water bills, site plans or hydraulic drawings, asset records, previous reports, access requirements, shutdown windows and the person authorised to approve further investigation.
Can leak detection be relevant before excavation?
Yes. The investigation is intended to narrow the fault location before excavation, demolition or repair work begins. Service locating and subsurface scanning may also be considered where suitable before excavation.
