Abstract

PURPOSE: To enable easy detection of a place of water leakage by the dry method without using water through discoloration of a temperature-sensitive discoloring liquefied substance when the compressed air of high temperature is sent into the inside of an inspecting part by coating the outside of the inspecting part with the substance.
CONSTITUTION: The temperature-sensitive discoloring liquefied substance 14 whose color is changed according to the temperature, such as, for instance, thermopaint and tempilstick, is applied on to the outer surface of the connecting part and the like of a watering pipe for which the inspection on water leakage is desired. Then, one end part of the watering pipe is closed tightly and the compressed air of high temperature is sent therein. When any place of water leakage is present, the air of high temperature leaks out of the place, which heats the above liquefied substance and changes the color thereof only at the place. Thus, the place of water leakage can be detected with ease.
