Leighton O’Brien’s precision tank and line test is the world’s fastest, most accurate method of leak detection. Using the very latest technology, there is no leak scenario our test cannot detect.

Certified to US-EPA standards, it’s the most advanced, practical and reliable test available. Our technicians can better diagnose problems including the smallest leaks, water ingress and equipment issues, so any repairs or rectification can be made sooner. And we can be off your forecourt quicker.

Tank test

• Independently USEPA certified as most accurate tank test globally
• Comprehensively engineered mass-based technology
• Uses multiple differential pressure sensors to continuously record mass readings in the wet area of the tank
• Mass readings during ullage test
• Ullage test time is 3 minutes (after stabilisation)
• Interstice monitoring / testing during tank test
• Ability to test all tank types at any fill level with any product
• Quality control built into the software
• Provides instant feedback to technicians, including live leak rate
• All readings are digitally stored and centrally analysed by qualified engineers
• No manual input needed, automated mass readings system

Line test

• Fastest USEPA certified test – as little as 3 minutes of data required for an empty line, 17 mins for wet line test
• USEPA certified to 0.01 gph (USEPA PASS/FAIL is 0.05 gph)
• Can perform both pressure and vacuum testing (up to 600 kPa)
• All line conditions can be tested including dry, wet and partially wet lines
• Certified for all pipe manufacturers including steel, plastic, single and double walled
• Proprietary software providing live volumetric results and feedback to testing engineer
• Readings are digitally recorded, stored centrally and analysis completed by engineers

• Our proprietary tank test technology can detect pressure changes of the smallest liquid movement
• We can detect a level change of 1/1000mm to identify any loss of fuel system integrity
• We can test your storage system in any configuration
• We can test tanks at any fill level, including empty tanks, with the same high degree of accuracy

• Testing just tanks is not enough – 90% of new sites we test have a leak in the product lines
• Our engineers make the final call on results through analysis of digital data to identify leak detection patterns beyond a simple pass or fail
