摘要： The object of the invention is to create a central water-loss prevention system which blocks the main water feed pipe after intentional or unintentional removal or leakage of a water volume limit fixed for each application, said limit being, in the opinion of insurers, below the limit for causing damage for each application, and consequently prevents further removal. The central water-loss prevention system in a main water feed pipe is characterised in that a volume counter comparing a volume limit fixed for the corresponding application with the volume removed is operatively connected to a shut-off device of the main water feed pipe in such a manner that when the preset volume limit has flowed through a command closing the shut-off device is triggered and when a volume limit lower than the preset volume limit has flowed through there is no triggering of the command closing the shut-off device. The invention relates to a central water-loss prevention system in a main water feed pipe from which a plurality of removal points or consumers can be supplied with water, for example the main water feed pipe of a detached house or a house for several families, the main water feed pipe of an individual flat or an individual business or a construction site water supply pipe. In such cases normal water removal for any removal volumes must be ensured and, at the same time, unintentional discharge of water must be prevented at the removal points and in entire pipe systems.
