Abstract
A showerhead includes a hollow housing with front and rear openings and a closure in the front opening which defines first and second groups of flow outlets. The showerhead is secured to a supply pipe by a nut which has a snout to captivate a ball and fix the position of a shank that projects from the ball and around which the housing is rotatable. A flow control device rotationally fixed on the shank enables selection of liquid flow through the ball and shank to selected ones of first and second channels that lead to corresponding first and second groups of flow outlets as the housing is rotated about the shank.
