Tracer gas water pipe leakage explained
Tracer gas for water pipe leaks is the most accurate way to find a hidden leak in a drinking water pipe without any demolition or breaking work. We inject a safe and low-odor mixture of nitrogen and hydrogen into a sealed pipe section. This gas, containing approximately five percent hydrogen, follows even the smallest leakage openings and migrates upwards via the floor, wall, or crawl space, where we detect it using sensitive H2 sensors. This technique aligns perfectly with NEN 1006 for drinking water installations and is safe for copper, PEX, PE, and PVC pipes. Drawing on knowledge from KWR Water Research Institute, NEN, and Kiwa certification, among others, we ensure a professional and reproducible process that works reliably in both residential and commercial buildings.
How tracer gas works in water pipes
Hydrogen is the smallest molecule and diffuses rapidly through capillary gaps. In combination with inert nitrogen, a non-flammable and non-toxic detection gas is created that can be introduced into the water pipe under low pressure. Our electronic sniffing probes locate the highest concentration of hydrogen and mark the exact leak point to the centimeter. We combine this with pressure measurement, acoustic correlation, and FLIR thermography to ensure an accurate diagnosis.
- Preparing piping section: shut off the water, drain, and perform a pressure test to confirm pressure loss
- Injection tracer gas: controlled insertion of forming with pressure gauge and anti-return device
- Sensor measurement: systematically scan with H2 detector around floor, skirting board, wall, crawl space and shaft
- Triangulation: interpret concentration differences and mark the exact leak point
- Verification: repeated measurement and additional thermography or electroacoustics for conclusive evidence
Leak detection process request
When do you choose tracer gas for a water pipe leak?
Tracer gas for water pipe leaks is ideal for invisible problems such as hot and cold taps, risers, and branches where no signs of moisture are visible, but pressure loss or a high water bill is present. This method also offers a high success rate under tiled floors, natural stone, and poured floors without destructive testing.
- Pressure loss without a visible cause: water meter keeps running, boiler refills frequently, pressure gauge drops
- Damp spot of no clear origin: ceiling stain, skirting board damage or mold on interior walls
- Long pipeline routes: apartments, hotels, and healthcare buildings with shafts and floor conduits
- Fragile finish: parquet, marble or designer concrete where demolition is undesirable

Our measuring equipment and protocols
Ultrices Leak Detection works with professional detection equipment from Trotec and Sewerin, among others, such as LD6000 and H2 sniffing probes with high selectivity, supplemented with digital pressure gauges, ultrasonic flow meters, and FLIR thermography. Our experts are VCA VOL and NEN 3140 certified and follow strict safety protocols, including ventilation and gas-free declarations for enclosed spaces. We apply best practices from European standards frameworks and laboratory experience with hydrogen detection, ensuring your installation is inspected in accordance with laws and standards.
- H2 sensor technology: electrochemical and semiconductor sensors with background compensation
- Pressure and debit analysis: quantify leakage loss for damage and insurance file
- Thermography: visualize temperature anomalies in hot water pipes and leakage plumes
- Acoustic verification: correlation and geophon for larger diameters or external pipes
Benefits of tracer gas for water pipe leaks
With tracer gas for water pipe leaks, you get speed, precision, and minimal disruption. The method is safe for drinking water installations and rarely leads to interruptions to business processes. Our success rate is very high, even at low pressure and with micro-leaks.
- Without hacking or breaking: finish remains intact and repair time is minimal
- High Accuracy: localization to the centimeter thanks to concentration gradients
- Safe and environmentally friendly: inert mixture with very low hydrogen concentration
- Quickly operational: measurement and reporting often started within the same working day

Types of leaks and application variants
Not every water pipe reacts the same way. We tailor the tracer gas strategy to the material, diameter, and location.
- Capillary microleakage: hairline crack in copper crimp or solder that only opens under pressure
- Perforation due to corrosion: puncture holes in copper or steel piping behind kitchen or meter cupboard
- Fitting or coupling: O-ring degradation in PEX press fittings and multilayer pipes
- Hot and cold tap water: anomalous thermal patterns that determine the detection strategy

Frequently asked questions
What is tracer gas for water pipe leakage and how does detection work?
With tracer gas leak detection, we shut off a section of your water pipe and introduce a safe mixture of hydrogen and nitrogen under light pressure. Hydrogen is the smallest molecule and seeks the path of least resistance, even through tiny hairline cracks. Using a highly sensitive detector, we follow the gas outflow through the floor, walls, and joints with centimeter accuracy. This allows us to find hidden leaks without any demolition work, even in concrete or under a tiled floor.
At Ultrices Leak Detection, we combine this with pressure tests, moisture measurements, and cross-measurements to provide you with a conclusive diagnosis. We are available nationwide, are often at your doorstep within an hour in emergencies, and deliver an expert report within three days. You will receive a free quote within 24 hours and benefit from our high success rate and no-cure-no-pay promise. Read how we detect leaks in the bathroom without demolition or breaking.
Is tracer gas safe for drinking water pipes and your home?
Yes, the tracer gas used typically consists of five percent hydrogen and ninety-five percent nitrogen. In this composition, it is non-flammable, non-toxic, and leaves no residue in copper, PEX, or PVC pipes. We ventilate specifically, flush the system, and monitor the pressure to ensure your installation remains safe. The gas does not affect materials such as concrete, plaster, wood, or tile grout, and does not disrupt your indoor climate.
If you see signs such as unexplained damp patches, a rapidly spinning water meter, heat stains on the floor, or loss of pressure, early testing is smart. We are VCA VOL and NEN 3 & 40 certified and work with insurers for a smooth settlement. Do you want certainty regarding your insurer? See how a clear leak detection report speeds up your insurance claim.
How quickly can you find a hidden water leak with tracer gas, and what does it cost approximately?
In emergencies, we are often on-site within an hour. The measurement itself usually takes between sixty and one hundred and twenty minutes, depending on pipe length, accessibility, and floor construction. Our working method is tightly organized, including intake and pressure testing, section sealing, injection of tracer gas, scanning and cross-measuring, marking the leak, and immediate repair advice. This limits consequential damage and prevents unnecessary downtime.
Costs vary by situation, but you will receive a free quote within 24 hours and a complete expert report within three days, including photos, measurements, and a floor plan that you can submit to the insurer. You benefit from our high success rate, guarantee of solid documentation, and no-cure, no-pay basis. Need urgent help? Need immediate help with a bathroom leak? Choose our emergency service.
Tracer gas, thermography, or acoustic leak detection: which is better for your situation?
The best method depends on your piping system and building construction. For plastic pipes in a screed, tracer gas almost always scores highest because it dampens sound and allows heat to dissipate. Thermography is strong for hot water pipes and underfloor heating with active temperature differences. Acoustic leak detection performs well for metal pipes with distinct flow noise.
In practice, we combine techniques for maximum certainty. Think of tracer gas for the exact pinpoint, supplemented with thermography to visualize heat trails and moisture measurements to define the contours of the damage. This provides you with a robust diagnosis that stands up to your insurer and prevents unnecessary demolition. We guide you along the right repair path with minimal disruption and maximum certainty.
