ABSTRACT:
The present invention discloses an operating mechanism for a cistern (1) or flush tank which is able to be used for a wide variety of cisterns, irrespective of their volume to depth profile. The preferred mechanism takes the form of a generally cup-shaped weir (22) which surrounds the flush valve (18) and from which a support frame (7) extends. The height of the rim of the weir is able to be selected or adjusted, for example by the use of a number of rupturable panels (24) located in the walls of the weir (22). A mechanism (26,27) to adjust for height variations between the flush actuators (14) and the flush operating mechanism (15) is also disclosed.
