Abstract
A sprinkler assembly can include a water inlet and a nozzle assembly. The nozzle assembly can include a nozzle tube having a nozzle positioned at the downstream end of the nozzle tube. The sprinkler assembly can include a user replaceable wear disc at least partially surrounding the nozzle tube. A deflector assembly can be connected to the nozzle assembly and can include a distribution plate positioned downstream of the nozzle and configured to deflect water from the nozzle. The deflector assembly can include a cage having one or more arms connected to the distribution plate and extending from the distribution plate toward upstream end of the nozzle tube. The deflector assembly can include an upstream collar portion connected to the at least one arm and having one or more load surfaces configured to contact the wear disc, wherein the wear disc is configured to bear at least a majority of a weight of the deflector assembly.
