Claim Text:
1. A fluid-leakage detection system for a domestic fluid distribution installation, comprising a main fluid feed pipe connected to at least one item of fluid consuming equipment through a corresponding secondary pipe, a control and management means able to generate a signal in the event of the detection of a leak, a cutoff valve for cutting off the main feed pipe, a small-leak detection device comprising a flow detector able to detect small fluid leaks and to send a corresponding signal to the control and management means, mounted in a bypass pipe connected to the main feed pipe, on either side of a bypass valve situated on the main pipe, the bypass valve being controlled by the control and management means and comprising an open position enabling fluid to pass through the main pipe to at least one item of consuming equipment and a closed position diverting the fluid to the bypass pipe through the small-leak detector, the detection system further including a flow meter on the secondary pipe of each item of consuming equipment, able to send a flow rate signal to the control and management means, which is able to continuously total the flow rate signals received, wherein whenever the global consumption is zero, the control and management means is further configured to put the bypass valve in the closed position and to perform the calibration of the zero consumption of each flow meter if the flow detector shows the absence of small leaks.
