When a water or gas leak is suspected but its source is not clear, leak detection can help focus the investigation. For homes, apartments and smaller private properties, clear observations, photos and access details can help a plumbing business understand the situation and discuss suitable testing and repair options.

A visible drip does not necessarily reveal where a leak begins. Water may appear in one area while the source is elsewhere, and a suspected gas leak may also require the location to be investigated rather than assumed. Leak detection is used when the exact location is not obvious and a more targeted investigation is needed before repair options can be discussed.
For homeowners, tenants, landlords, strata owners and property managers, the useful starting point is a clear description of what has been noticed. Explain where the issue appears, when it was first observed and whether it seems to be changing. A leak detection plumber can then consider the information available and the approach that may suit the property.
What leak detection may involve
Leak detection can involve non-invasive or targeted investigation. Depending on the suspected issue and the site, a plumbing business may use site observation, moisture investigation, listening equipment, trace gas or other location testing to narrow down where a leak may be occurring.
The purpose is to build a clearer picture of the issue before repair options are considered. Findings and potential repair pathways can then be discussed in relation to the affected area and the property’s circumstances.
Testing approaches you may hear discussed
Two specialist approaches associated with residential leak detection are acoustic testing and hydrogen gas injection testing. They are options for investigating a suspected leak where the location is not immediately apparent; the appropriate approach depends on the issue and the property.
Acoustic testing
Uses listening equipment as part of an investigation into a suspected leak. You may also see this described as acoustic water leak detection.
Hydrogen gas injection testing
Uses trace-gas testing as part of locating a suspected leak where further investigation is needed.
Underground water leak detection may be part of the conversation when water is suspected below ground and the location is unclear. A plumbing business can discuss the observations available, access to the area and the testing options it considers relevant.
Useful details to have ready
Good information helps a plumbing business assess a suspected leak more clearly. There is no need to diagnose the problem yourself; plain-language observations are valuable.
Provide the property address, a contact person and the best access instructions.
Describe the issue, the surrounding area and what you have observed.
Share photos or short videos of the affected area, nearby equipment or pipework, and any visible labels on existing equipment.
Explain whether the area is occupied, whether water or gas can be isolated, and any urgency or safety concerns you are aware of.
Mention relevant property details, such as the age of the home or whether it is tenanted.
These details do not replace an investigation, but they can help frame the initial conversation and the likely repair pathway once findings are available.
Choosing a plumbing business for leak detection
Ask whether the plumbing business can discuss the suspected issue, the information it needs and the testing approach it may consider. It is also helpful to understand how findings and repair options will be communicated after the investigation.
Find a Master Plumber connects customers with Master Plumbers and plumbing businesses associated with the Master Plumbers and Gasfitters Association of Western Australia. It is backed by the Association, which has represented Western Australia’s plumbing and gasfitting industry since 1901. Choosing a Master Plumber helps consumers make a more informed choice of plumbing business for their property or project.
Brands and products you may encounter
During discussions about leak investigation, equipment, existing installations or supply options, customers may encounter names such as Sewerin, Gutermann, Vivax-Metrotech, Ridgid, Rothenberger, Leica Geosystems, Fluke, Testo and Protimeter. Reece, Galvins, Galvin Engineering, Tradelink, Parkwood Plumbing Centre, Bunnings and Plumbing Plus are also names associated with plumbing products and supply channels. These are examples customers may encounter, not recommendations or an indication that every plumbing business uses particular products, equipment or suppliers.
Related residential plumbing concerns
A suspected leak can sit alongside other household plumbing concerns. If the issue appears connected to drainage, a blocked drain, roof plumbing, sewer, storm water or a water pump, those service areas may help you describe the broader problem when choosing a plumbing business. For a water or gas issue with an uncertain source, leak detection remains the relevant starting point for discussing investigation options.
