<p>A valve assembly (10) comprises a valve (14) for controlling a flow of fluid from a fluid supply. The valve has a first configuration and a second configuration, the first configuration is arranged to allow a greater mass flow rate to flow from a supply than the second configuration. The valve assembly comprises a sensor (18) arranged to sense liquid, such as water on a surface. The valve is arranged to be switchable by wireless control means fro the first configuration to the second configuration or vice versa when liquid is sensed.</p> |
