Leakages which can not be pinpointed using traditional location methods need more elaborate location technology. With the gas-feed-in method, the empty water pipe is filled with a special gas mixture. Characteristically, the leak-detection gas released at the leak location flows directly in a straight line up to the surface. This leak-detection gas is detected at the surface using gas detectors; in this way the damaged spot in the piping can be located.
