The SNIFFER430 is an advanced water leak detector that uses the tracer gas technique to quickly and reliably locate even the smallest water leaks in underground, underfloor, and in-wall pipes.
Sniffer430 readily detects water leaks in underground plastic, or metal piping. Leaks are detected under different types of soils, grass, or stone pavements with high reliability and at a significant depth.
Sniffer430 is very effective in underfloor water leak detection. High sensor sensitivity allows fast detection of the smallest water leaks under wooden, ceramic tile and other types of flooring.
Sniffer430 provides an excellent solution for finding a leak source in walls, in hard-to-access areas, behind furniture, and without direct contact.
Sniffer430 is easy to use, light and ergonomic device that comes with a large 7-inch capacitive touchscreen, hand and neck straps as well as a protective silicone cover.
Sniffer430 has a novel design of the wireless sensor with a built-in air pump that allows extremely fast detection of hydrogen even in small concentrations.

Sniffer 430 is the ultimate leak detection system for small diameter water pipes. It operates using the tracer leak detection technique. A tracer gas (5% hydrogen and 95% nitrogen mixture) is injected into examined piping (underground, underfloor or other) under small pressure. Afterwards, inspection is performed to detect the area where the gas is escaping from a pinhole, crack or a leaking joint. Leak detection using tracer gas is especially suited for small diameter water lines in houses, gardens, air condition lines and others. Leaks are readily detected deep underground (3-4 meters), under ceramic or wooden floors or under concrete. In some cases, small drillings are performed on concrete to allow better gas passage.
The main advantages of Sniffer 430 system and tracer gas equipment in general compared to acoustic methods are:
Sniffer 430 detects even small leaks that do not produce friction/turbulent flow.
Sniffer 430 is not limited to any type of piping materials (metal, plastic, composite and etc.).
Sniffer 430 can effectively detect leaks even under small pressure levels below 1 bar.
In-home leak detection system Sniffer 430 provides multiple advantages compared to thermal camera inspections. These include:
Sniffer 430 detects real source of leak. Thermal cameras detects hot/cold spots where water accumulated while the real leak source can be at significant distance.
Sniffer 430 leak detection is not limited in wet, high moisture or areas with reflecting ceramic tiles.
Unlike thermal camera, Sniffer 430 detect leaks which are not necessary in eye contact, for example if leaks are located behind kitchen cabinet.
Possible limitations of tracer gas technique are:
You need a tracer gas for examination and pipe should be shut off and pressurized by the gas.
Impractical to test large diameter pipes because of large volumes of gas needed.
To summarize:
Sniffer 430 system is must to have for fast, reliable and accurate leak detection in underground and under slab piping, outdoor and indoor applications!
Tracer Gas Volume
Tracer gas volume calculation is important prior to every use of Sniffer for leak detection. Of course, each pipe has its own length and diameter. Also, you may need to apply different levels of pressure. The formula to evaluate the amount of gas is simple: Gas Amount = π x L x D^2/4 x P, where L is the pipe length, D is the piping’s internal diameter, P is applied pressure.
Example:
Let’s say, you have 100 meter long pipe with a 100 mm diameter. You plan to pressurize it by 1 bar pressure. Therefore, you will need 785 liters of at 1 bar pressure.
Practical Tips:
In most cases, you do not need to remove all water from the tested piping to perform a tracer gas leak test.
Take into consideration that a leaking pipe will constantly lose gas.
You can assess the tracer gas volume needed by accumulating water drained from the pipe.
