Two of our most powerful methods solve the same problem — pinpointing a hidden pressurized leak — in completely different ways. Understanding when each wins explains why a good investigation sometimes uses both.
Strengths: fast to deploy, no system modification needed, excellent on metal pipe, works through slab and soil, and the operator hears results in real time. Best for: slab leaks in copper systems, service lines at moderate depth, any pressurized leak where the pipe carries sound well. Weaknesses: struggles with plastic pipe (poor sound transmission), very deep burial, and high ambient noise environments.
Strengths: doesn't need sound at all — the gas physically escapes through the leak and surfaces above it, making it decisive for plastic pipe, deep lines, and cold-water slab leaks with no thermal signature. Best for: leaks that defeated acoustic, long underground runs, and plastic service lines. Weaknesses: requires isolating and draining the section first (more setup time), and very porous ground can diffuse the gas broadly.
The decision tree: pressure test first (confirm and narrow). If the pipe is metal and conditions are reasonable, acoustic usually goes first — it's faster. If the pipe is plastic, deeply buried, or acoustic already failed, tracer gas is the call. Often the honest answer is sequential: acoustic surveys, tracer gas confirms. The methods agree, the mark goes down, everyone's confident.
You don't need to choose — that's our job. But now you know why we might start with headphones and end with a gas detector, and why a company that only owns one method will recommend that method for every leak. Ask any provider what they do when their primary method fails; the answer tells you everything.

Yes — the standard blend is 95% nitrogen, 5% hydrogen: non-flammable, non-toxic, dissipated harmlessly. It's the same principle utilities use.
Both are accurate in their element. Accuracy comes from matching the method to the conditions — and cross-checking — not from one method being universally superior.
It takes more time, but a located leak is infinitely cheaper than an unlocated one. The expensive outcome isn't thorough detection; it's exploratory demolition.
