Abstract
A sprinkler (10, 10') including a riser assembly (14) and a removable nozzle module (34) operatively connected thereto. Nozzle module (34) includes a nozzle holder (36, 36') and a nozzle (38). Nozzle holder (36, 36') is accessible even when sprinkler (10) is buried and the riser assembly (14) is completely retracted. In a preferred embodiment, a bayonet fit exists between nozzle module (34) and riser assembly (14) so that it is only necessary to twist nozzle module (34) a few degrees to disconnect it from riser assembly (14). Once nozzle module (34) is removed, nozzle (38) can be replaced or unplugged as necessary. Sprinkler (10') preferably includes a security cover (77) which, when in place, prevents access to nozzle module (34) and prevents removal of same from the riser assembly rotating portion (30).
