Abstract

The subject of this invention is a method for detecting leaks in a water supply system, in which method the water meter (2) is examined and note made of changes occurring in it. In the method according to the invention, changes are observed during one or more desired length measuring time periods (T) and the duration of flow of a quantity of water (t; t, t1, t2), during the measuring time period is measured using the water meter indicator and the results obtained during the measuring time period are compared with a standard value or with each other and confirm a possible leak.
