Stop Referring Leak-Location Jobs to Someone Else’s Truck
A $2,950 tracer gas detector lets your own crew pinpoint hidden leaks the same day — so the location fee and the repair job both stay on your invoice.
Every leak you can’t locate is a job you hand to a competitor
When a slab leak, underground line, or hidden pipe leak shows up on a service call, most plumbing companies without in-house detection equipment have two options — both of them costly.
Sub out the location work
You pay a third-party leak detection company $150–$1,000+ per job just to find the leak. That fee — plus the customer relationship during diagnosis — leaves your business.
Lose the repair, too
Many leak-detection firms bid the repair themselves once they’ve located the leak. You referred the customer — and they walk out with the higher-margin repair ticket.
Bring tracer gas leak location in-house
The H2Leak tracer gas detector pinpoints leaks in slabs, underground lines, and inaccessible pipe runs by tracking a hydrogen-nitrogen tracer gas through the smallest crack — accurate to within inches, without demolition test-digging. Your technician runs the same locate a specialty firm would, on the same truck roll, for the same customer.
- ✓ Locates slab, underground, and wall leaks in one visit
- ✓ No subcontractor scheduling delay — quote and repair same day
- ✓ Reusable on every future job at near-zero marginal cost
H2Leak Hydro-Lok: the detector behind the ROI
Hydro-Lok is a portable H2/N2 tracer gas leak detector built for worksite and maintenance use — a hydrogen-selective sensor, OLED graphic display, and a 60 cm flexible shape-memory probe with an interchangeable sniffing cone or point tip for locating small leaks. Made in France, with wear parts serviced directly by the manufacturer.
- ✓ Sensitivity to 1 ppm H2 under optimal conditions of use
- ✓ ~8-hour battery life, USB-C charging, full charge in ~12 hours
- ✓ Compact, shockproof housing at just 0.35 kg
The math: how a $2,950 detector pays for itself
Outsourced leak location typically runs $300–$450 per residential job (up to $1,000+ for complex slab or underground work). Charge that same diagnostic fee yourself, and the detector is paid off in single digits of jobs — with every job after that running near-pure margin.
Figures assume a ~$5 per-job tracer gas consumable cost and no repair-capture revenue. Source ranges for outsourced locate pricing: Angi, Homewyse, CPI Service, UseCalcPro (2026 published rates).
What changes when you own the detector
Common questions from plumbing companies
How much does a tracer gas leak detector cost?
The H2Leak Hydro-Lok tracer gas leak detector is $2,950 as a one-time purchase. Ongoing cost per job is limited to the tracer gas cartridge, typically a few dollars per locate.
How long until a plumbing company sees ROI on a leak detector?
Charging the same $300–$450 diagnostic fee a third-party leak detection company would charge, most plumbing companies recover the $2,950 purchase price in roughly 7–10 locate jobs — often within the first one to three months.
Why not keep subcontracting leak location to a specialist?
Subcontracting sends the locate fee — and often the follow-on repair job — to another company on every single call. Owning the detector keeps both revenue streams in-house indefinitely, with no per-job outsourcing cost after break-even.
What leaks can tracer gas detection locate?
Tracer gas detection pinpoints leaks in slab foundations, underground water lines, in-wall plumbing, refrigeration and HVAC lines, and other concealed runs — without exploratory demolition — by tracking a hydrogen-nitrogen tracer gas escaping through the leak point.
