Claim:
1. A self-cleaning sprinkler comprising: a. an upper and lower housing connected to one another for positioning the self-cleaning sprinkler; b. a nozzle fastened within the upper housing for expelling water from the self-cleaning sprinkler through an exit aperture; c. a diaphragm coupled to the upper and lower housings, moveable between an open and a closed position to allow a flow of water through the nozzle; and, d. a needle secured within the diaphragm to expel debris out of the exit aperture of the nozzle when the diaphragm is in a closed position; wherein the diaphragm is dome-shaped in the closed position, the dome shape self-biasing the diaphragm in the closed position, thereby preventing the flow of water through the nozzle.
