When this method is useful
Acoustic testing may help with pressurised water supplies, buried mains and accessible pipe connections. A useful result depends on the pipe material, pressure, escape characteristics and background noise.
What happens during the investigation
We choose listening positions based on the likely route and compare the character and strength of the sound. Findings are considered with isolation evidence and the physical layout before an access location is suggested.
What it cannot establish on its own
Traffic, pumps and normal flow can produce misleading noise. Some plastic pipes, deep routes or small escapes transmit little usable sound, so silence does not establish that a system is leak-free.
How we combine the evidence
Pressure checks help establish the suspect system; tracer gas may add evidence where listening conditions are poor.
Good detection is a sequence of decisions. We use the observations to narrow the question, check whether the results agree and explain the practical implications before proposing access. This helps you understand the reason for the work rather than simply seeing a piece of equipment in use.
Preparing for the visit
Mention pumps, automatic appliances and nearby traffic conditions. Keep safe access to useful valves and connections available.
The method is part of the service
The engineer selects suitable methods within the agreed investigation. Our £1,750 residential package also includes necessary access or excavation, the plumbing repair, parts, materials, appropriate retesting and an Written Trace & Access report. It is not a promise to use every listed technique at every property.
All our work within the agreed scope has a one-year workmanship warranty. Decorative and remedial reinstatement is excluded. Commercial work receives an individual quotation.
Documenting useful findings
Where a result supports the investigation, the report explains its relevance to the source, access or repair. Photographs are included where appropriate. The report can support an insurance submission, but your insurer determines eligibility and reimbursement under your policy.
