PURPOSE: A press type fire extinguishing water feeder capable of using waterworks (domestic water, and industrial water) as secondary fire extinguishing water is provided to reduce capacity of existing fire extinguishing water tank, thereby suppressing fire at the beginning. CONSTITUTION: A press type firefighting water feeder capable of using waterworks (domestic water, and industrial water) as secondary firefighting water comprises a fire extinguishing water tank(100), an air tank(200), a fire extinguishing water supplying pipe(400), waterworks, a waterworks supply tube(500), a voltage transformation nozzle(600), and a sprinkler(700). The waterworks supply tube is connected to the voltage transformation nozzle in order to supply waterworks as secondary fire extinguishing water. The voltage transformation nozzle is connected to one side of the waterworks supply tube and the fire extinguishing water supply tube and provides the fire extinguishing water with the sprinkler. The voltage transformation nozzle provides waterworks to the sprinkler through the waterworks supply tube.
