A method for reserve water supply includes forced filling of collection tank with water from system of central water supply. Water from system of central water supply is fed through tap, tee-bend and rough purification filter to collection tank, and through control valve - to consumer. In collection tank water level is controlled by means of float-valve. Pressure balance in the tank is controlled by air valve. At switch-off of water in mains of central water supply water from the collection tank is supplied to consumer through water pressure booster and control valve.
