FIELD: water supply systems, particularly for emergency shutting-down of water supply in plumbing system of building, for instance during water pipeline breaking and so on.
SUBSTANCE: device has water-dispensing fittings arranged on water supply pipeline and stop valve installed upstream water-dispensing fittings. Stop valve begins its operation in presence of water leakage. Device has water sensors. Each water sensor is formed as two open electrodes connected to floor and is arranged under corresponding water-dispensing fitting and under drain orifice of sink, wash sink, bath, shower or spill tank of lavatory bowl. Safety stop valve is formed as normally-opened electromagnetic valve linked to sensors through control unit. Supply pipeline is riser pipe for water feeding into apartment.
EFFECT: prevention of building flood in conditions of often water supply interruption.
