At the same time, as there is no electricity, new tap water will certainly not be produced; if the residence does not have electricity, the natural elevation of the tap water (10 m) below the third floor will not be affected. The water tank supplies water. Since the water pump cannot work, water cannot be sent to the water tank on the roof. It can only be powered by existing stored water until it runs out.
