A lever action tap (US: faucet) has a rotary control for manually regulat ing the flow of water through the tap to a spout, and is adapted for hospita l environments, including pre-surgical scrubbing up. The control comprises a long lever arm (3) and a short lever arm (4), either lever arm being operab le to operate the control, the lever arms being mounted with a predetermined angular separation about the axis. The angle of rotation between the open a nd closed states is substantially equal to 90°. The arrangement is such that the long lever is arranged to rotate upwards and away from the user in movi ng from the open state to the closed state. The short lever arm is arranged to rotate downwards and away from the user, in moving from the closed state to the open state. |
