A water sprinkler comprises a housing formed with an inlet bore connectable to a source of pressurized water; a tubular connector having one and received within the inlet bore, and its opposite end connectable to the source of pressurized water; and a strainer element supported within the inlet bore by the tubular connector when the latter is received within the inlet bore. The strainer element is formed with a plurality of open notches along its outer edge defining a plurality of passageways of small cross-sectional area blocking the flow of solid particles to the sprinkler, which passageways may be immediately and thoroughly rinsed of the solid particles by merely removing the tubular connector and its strainer element from the inlet bore while the tubular connector is connected to the source of pressurized water.
