The method and apparatus relates to a procedure and an arrangement for minimizing the risk of the undesired escape of water from pipe systems and units connected thereto in premises and similar surroundings by the use of a control or valve arrangement arranged at the point of connection of the pipe system to the external supply pipe and capable of regulation by means of an adjuster device. A link is provided between the valve arrangement and the device for detecting the presence or movement of individuals inside the premises, and the operation is such that, in the event of the detection of presence or movement, the valve is kept open so as to permit water to enter the pipe system or network, whereas the valve is kept closed in the absence of such detection.
A method of minimizing risk of leakage of water from a pipe system supplying water from a main supply line to one or more output points in a premises, comprising the steps of providing a valve between the pipe system and the main supply line, detecting whether there is at least one of presence or movement of an individual within the premises independently of demand for water any output point, automatically maintaining said valve in an open state when said one of presence or movement is detected and automatically maintaining said valve in a closed state when said one of presence or movement is not detected.
Apparatus for minimizing risk of leakage of water from a pipe system supplying water from a main supply line to one or more output points in a premises, comprising a valve disposed between the pipe system and the main supply line, means for detecting if there is at least one of presence or movement of an individual within the premises independently of demand for water at any output point, means for automatically opening said valve when said one of presence or movement is detected, and means for automatically closing said valve when said one of presence or movement is not detected.
