Abstract

An arrangement for preventing tap-water damage in building structures caused by leakage of water from a pressurized water system (16, 20). The arrangement includes a fitting which comprises a closure valve (12) and a pressure sensor (13), which are connected to the incoming pressurized water conduit (11), and a control device (14) in the form of an electronic unit which is placed in a convenient location in the building. In the case of normal water withdrawals from the various tap points (16) of the system, the control device will open the valve from its closed position, but in the event of a leak will issue a warning thereof and/or or lock the valve in its closed position. The electronic unit is constructed to register different pressures, pressure differences and time periods together with the course taken by certain events, in a maner to instigate the issue of a warning signal or locking of the valve in its closed position when the parameters registered do not fall within the programmed values of conceivable normal withdrawals of water from the system. The program and the parameters are adapted particularly to the pressure characteristic applicable to the water supply system concerned. Particular account is paid to whether the system contains air enclosures or not. The electronic unit is constructed to open the valve (12) when a given pressure difference is measured relative to a comparison pressure calculated suitably on the conduit pressure of the system.
