A water stream stop valve for a sprinkler includes a tube body, an annular cover, multiple securing units, and a drainage body having a hole at the center thereof, is arranged above the tube body by multiple support plates. The water stream stop valve is incorporated in a pop-up sprinkler that includes a main body, an expansion pipe with a stop member arranged at top internal diameter thereof, a spray head, and the water stream stop valve arranged inside the expansion pipe and below the spray head. When the spray head falls off expansion pipe, the water stream stop valve will be pushed up to the top of the expansion pipe and stop at the stop member for avoiding the overflow of water while maintaining the spraying at the original area, and delivering a service indication stream.
