Abstract
The present invention relates to a dual flush cistern. The cistern incorporates a flushing valve 12 located in the base of the cistern, the flushing valve 12 having a stem 11 able to be lifted to open the flushing valve 12. Float 30 is fixed to stem 11 and is mounted within float housing 13. Float housing 13 is mounted relative to the cistern such that it is below the normal water level when the cistern is full and above the normal water level following a partial flush. The closure of flushing valve 12 is dependant on float 30 which falls with the water level within float housing 13. The drainage rate of water from float housing 13 is controllable in response to the type of flush desired.
