The invention relates to a device for the detection of leaks in a distribution system, which is intended to detect low-flow leaks. The inventive device consists of: a first conduit (100) which is intended to be disposed between the water supply system and the water distribution system, said conduit comprising means for the passage of the water that is to be distributed when the pressure difference between the distribution system and the supply system exceeds a first determined threshold; a second conduit (126) for the passage of the water that is to be distributed when said pressure difference exceeds a second lower threshold; and an alarm means (136; 150) which provides a signal when the water passes through the second conduit and, preferably, not through the first conduit. |
