A water flow-controlling device has a tube, a shaft, a block, a washer and a reciprocating assembly. The tube has a front opening, a rear opening, a side opening and a rear bracket. The openings communicate with one another. The rear bracket is mounted in the tube near the rear opening. The shaft is mounted in and is aligning with the tube and is mounted movably in the rear bracket. The block and the washer are mounted on the shaft. The block selectively obstructs the communication between the front and side openings. The reciprocating assembly connects to the shaft to move the shaft to align with the tube. The reciprocating assembly moves the shaft to extend out of the tube or the inner pressure pushes the block to prevent the block from obstructing the communication between the front and side openings.
