A different way to investigate a hidden route
Some leaks provide limited sound or visible evidence. On suitable pipework, a controlled tracer test can help identify where a test mixture emerges and add information about the concealed fault.
Preparation is part of the method
The relevant section needs to be assessed and prepared by the engineer. Isolation and safe operating conditions matter. This is a professional test, not a substance to introduce into your own water system.
The surface reading needs interpretation
Gas can move through layers and voids before reaching the detector. A reading is considered with the pipe layout and other evidence, rather than automatically marking a spot directly below it for excavation.
