When there is a gas smell, a hissing sound, unreliable appliance ignition or LPG bottles appearing to empty sooner than expected, the priority is to treat the situation seriously. Bottled LPG can serve important equipment across a commercial or industrial site, so an apparent leak may need to be considered alongside safe access, isolation arrangements and the operational impact of taking equipment out of use.
LPG (bottled) leak work sits within commercial and industrial gas fitting. It may relate to bottled or bulk LPG systems serving commercial kitchens, workshops, hospitality venues, temporary facilities, mobile plant, boiler systems, industrial appliances and other gas-fired equipment.
What to do if LPG can be smelt
Commercial sites often have practical constraints that need to be managed at the same time, including occupied areas, restricted access, plant locations, inductions and shutdown restrictions. Tell the plumbing business about these conditions early so the site and the work can be considered properly.
Where a bottled LPG leak may be investigated
A commercial LPG installation can have high-pressure and regulated low-pressure sections. Higher-pressure components are commonly found around cylinders, bulk tanks, manifolds and first-stage regulators. The regulated side usually supplies appliances such as boilers, cookers, ovens, heaters or process equipment.
Depending on the installation, the work may involve LPG cylinders or bulk tanks, manifolds, regulators, pressure pipework, isolation valves, safety devices, appliance connections and ventilation considerations. Equipment may be located in an external cylinder cage, bulk tank compound, rear service yard, plant room, rooftop, loading area, commercial kitchen, boiler room or fenced service zone.
Gas leak investigation can involve isolating sections of the system, pressure testing, gas detection equipment and checks of appliance connections and regulators. The precise scope depends on the asset, reported symptoms, access, isolation points and the consequence of failure.
Signs that warrant attention
Not every symptom confirms a leak, but the following are useful details to report when seeking commercial LPG gas leak detection or repair:
a smell of gas;
a hissing sound near LPG equipment or pipework;
appliances that fail to ignite or operate as expected;
LPG bottles becoming empty sooner than expected;
recent gas supply issues; or
advice from a gas supplier that the installation needs a gasfitter.
These observations help describe what has been noticed without assuming the cause. They can also help distinguish an immediate service call from a planned repair or a larger scoped item.
Information that helps a plumbing business assess the site
Good site information makes it easier to discuss commercial bottled gas leak detection, access and the likely effect on operations. Before making contact, gather what is readily available:
Identify the asset: site address, business type, gas supplier, cylinder or tank size, number of cylinders or tanks, and the location of the affected equipment.
Describe the symptoms: whether gas can be smelt, any recent supply issues, appliance fault codes and where the issue was first noticed.
Share useful visual details: photos of cylinders, regulators, visible pipework, appliances and labels, plus appliance make, model and serial number where available.
Explain site conditions: access instructions, occupied areas, shutdown restrictions, induction requirements, parking or loading details, and permitted working hours.
Set out operational controls: the person authorised to approve work, relevant asset IDs, plant location, service records, isolation status and any required permits or safety controls.
For industrial operations, it can also be important to explain process impacts, critical production considerations and the available shutdown window.
Pressure scope and the right gasfitting authority
Some LPG systems include piping operating above 200kPa. In Western Australia, gasfitting work on piping above that pressure falls within a specific gasfitting scope. When discussing commercial LPG gas leak repair, ask whether the attending gasfitter holds the correct gasfitting authority for the work required.
This is particularly relevant where cylinders, bulk storage, manifolds and higher-pressure pipework form part of the installation. Providing photographs and equipment details can help make that conversation more specific.
Equipment and names customers may encounter
Commercial LPG systems can bring together gas supply, appliance and plumbing-product components from a range of sources. Examples customers may encounter include Kleenheat Gas and Origin in gas supply channels; Reece, Galvins, Tradelink and Plumbing Plus in plumbing-product supply channels; and equipment names such as Rinnai, Rheem, Bosch, Bromic, Hobart and Luus.
Existing labels, manuals and serial numbers can help identify the equipment being discussed. These names are examples only and do not indicate that every plumbing business supplies, installs, services or recommends a particular product or brand.
Choosing a Master Plumber for commercial LPG work
Gas fitting work needs to account for the gas system as well as the site’s access, safety and continuity requirements.

Customers can use the directory to choose a plumbing business for LPG leak investigation, commercial LPG gas leak detection or commercial bottled gas leak repair.
What should we do if we smell bottled LPG at a commercial site?
Treat the area as urgent, avoid ignition sources and contact the gas supplier or an appropriately licensed gasfitter immediately. Do not try to repair, alter or test the LPG system yourself.
What information should we provide about a suspected LPG leak?
Provide the site address, business type, gas supplier, cylinder or tank details, equipment location, reported symptoms, available photos, appliance details, access instructions and any shutdown or induction requirements.
Can an LPG leak concern involve equipment other than bottles?
Yes. An LPG system may also involve bulk tanks, manifolds, regulators, pipework, isolation valves, appliance connections and associated safety devices.
Why do access and shutdown details matter?
Commercial and industrial sites may have occupied areas, plant locations, induction requirements and operational restrictions. These details help a plumbing business understand the site conditions and possible disruption to operations.
When should we ask about gasfitting authority?
Ask when the LPG installation includes piping operating above 200kPa. In Western Australia, that work falls within a specific gasfitting scope, so the correct authority should be confirmed.
When using Find a Master Plumber, describe the LPG equipment, observed symptoms and site conditions as clearly as possible. This helps you choose a plumbing business suited to the work and the operating requirements of the site.
