Certain exemplary embodiments can provide a system that comprises a valve coupled to a water supply to a showerhead. The valve is constructed to turn a water flow on and off to the showerhead. The system comprises a first switch mounted outside of a shower stall. The first switch can be constructed to, responsive to a first user action, cause the valve to turn the water flow on.

A jet regulator (101) having a sleeve-shaped jet regulator housing (7) which is capable of being assembled on the water outlet of a sanitary outlet fitting, and having a wall (3) which supports a perforated structure (4) that forms the outlet end side of the jet regulator (101) and which in the jet regulator housing (7) is pivotable between a use position, in which the perforated structure (4) extends transversely across an outflow-side sleeve opening of the jet regulator housing (7), and a cleaning position, in which the water flowing through the jet regulator housing (7) can flow out of the jet regulator housing (7) on both sides of the wall (3) through opening gaps (8, 9) that are formed between the wall (3) and the neighboring housing internal circumferential wall. It is characteristic of the jet regulator (101) according to the invention that the wall (3) has a spherical-layer-shaped external circumference (5) and by way of said spherical-layer-shaped external circumference (5) is pivotably mounted in a joint socket (6) which is provided on the housing internal circumferential wall of the jet regulator housing (7).

A ball joint connector is provided for linking a showerhead to a water supply pipe. The connector has an internal venturi that draws air into the connector to aerate water being provided to the showerhead. A flow control member is disposed in a fluid pathway connected to the venturi, preventing spraying or leaking out of the air inlet, while reducing noise associated with the air induction.
