The Challenge
High Water Usage Reported By Supplier
The customer had been contacted by their water supplier due to excessive water use. No confirmed repair route had been established, so a specialist mains water leak investigation was required.
- ✓ Water supplier reported excessive water use
- ✓ A hidden mains water leak was suspected
- ✓ The leak source needed to be located before access and repair could be arranged
- ✓ The investigation focused on the water meter and external supply route

Investigation
Tracer Gas And Acoustic Mains Leak Investigation
Tracer gas and acoustic detection were used to investigate the suspected mains water leak route and narrow the likely leak location.
Tracer Gas Supply Route Test
The water supplier had reported excessive use, so the concealed supply route needed to be tested without broad access work.
Tracer gas was used along the suspected mains water route to help narrow the likely leak position.
The test supported a more focused investigation around the kerb-side water meter area.
MethodAcoustic Leak Listening
Acoustic detection was appropriate because the suspected issue involved pressurised mains water pipework.
Acoustic checks were used alongside tracer gas during the mains leak investigation.
Combining both methods helped identify the likely leak position for water board access and repair planning.
Findings
Leak Located Near The Kerb-Side Water Meter
The leak was located at the kerb-side by the water meter, giving the client a clear position to discuss with the water board for access and repair.
- The water meter area was inspected
- Tracer gas equipment was used during the investigation
- Acoustic detection supported the location process
- The likely leak position was identified at the kerb-side by the meter
Outcome
Leak Location Confirmed
- ✓ Leak Located
- ✓ Mains Water Investigation
- ✓ Non-Destructive Methods
- ✓ Repair Route Identified
The leak location was confirmed. The client was advised to contact the water board to arrange the relevant access and repair steps.
Investigation Insights
What This Investigation Shows
- ✓High water usage can require specialist testing even when the leak is not visible inside the property.
- ✓Using tracer gas and acoustic detection together can reduce uncertainty on a suspected mains supply route.
- ✓A confirmed kerb-side location helps separate leak detection findings from the later access and repair process.
