Abstract: In some embodiments, a sprinkler head is disclosed. The sprinkler head can include a spray stem comprising an upper stem rotatably coupled to a base stem; a spray nozzle coupled to a distal end of the upper stem; and a connector for removably coupling the sprinkler head to a pressurized liquid source. An interior cavity of the base stem can be in fluid communication with an interior cavity of the connector, and the upper stem can rotate between an operational position where an upper stem interior cavity is in fluid communication with the base stem interior cavity and a maintenance position where the upper stem interior cavity is not in fluid communication with the base stem interior cavity. A pop-up sprinkler head including the spray stem described herein is also described.
