Escaping water can create sound that travels through the pipe and surrounding ground. Engineers listen at accessible fittings and use ground microphones to compare sounds along a suspected route. Background noise, pressure and pipe material affect what can be detected. Ask what evidence supports the marked position before excavation.
A correlator compares noise recorded at separate contact points to help estimate a leak’s position between them. Useful results depend on suitable contact points and accurate information about the intervening pipe. It is one investigation technique, rather than a guarantee that every leak can be located.
A specialist introduces a suitable tracer gas under controlled conditions and checks for gas emerging at the surface. This may help where acoustic investigation is inconclusive. Ground conditions and gas migration can affect the apparent position, so the findings still need interpretation. Ask how the supply will be isolated and returned to service.
Confirm whether the price covers investigation only or also excavation and water pipe repair. Ask what report or location evidence you will receive and what happens if the first method is inconclusive.
