Abstract

A syphonic flushing device (10) for attachment to a water cistern characterized in that the device (10) comprises a syphon member (12) having a float compartment and having a first inlet (22) and an outlet (46) to allow the flow of air or water through the syphon member (12), the device (10) being movable between a first position corresponding to an upper water level (F-F) in the cistern and a second position corresponding to a lower water level (E-E) in the cistern, wherein when the device (10) is operated water will flow through the syphon member (12) to move to the second position whereupon air enters the device (10) as the water level in the cistern falls below the first inlet (22) causing the flushing action to cease whereupon air will flow through the syphon member to substantially fill the float compartment causing the syphon member (12) move to the first position as the water level in the cistern rises.
