If a defective pipe has a large difference height, the possibility exists of determining the level of the fault by means of pressure measurements. Often, only a rough estimate of the leakage location can be made using this method. Such measurements can, however, provide a clue to where the leak can be: furhter leak location is then carried out eith the aid of ground microphones.
