Beschreibung
Zusammenfassung:	An irrigation sprinkler includes a main valve mounted in the lower end of an outer housing for controlling the flow of water through an inlet of the outer housing. A pilot valve is operatively coupled to the main valve for turning the main valve ON and OFF. A solenoid is operatively coupled to the pilot valve for opening and closing the pilot valve. A service valve is operatively coupled between the main valve and the pilot valve. The service valve is manually actuable from an AUTO state to allow normal operation of the sprinkler and to an OFF state to allow repair or replacement of the pilot valve or solenoid without having to manually shut OFF a supply valve that is coupled to the inlet of the outer housing through a supply pipe.
