Abstract: PURPOSE:To detect the presence and position of a leak of water without requiring skill. CONSTITUTION:A cock S11 is preliminarily closed on the day before the leak test of a water pipe L11 is performed and, tomorrow morning, the impedance value Z11CA in the ground between points C1 and A1 is measured in such a state that the cock S11 is closed.
