ABSTRACT:
The mechanism comprises an inlet valve assembly which admits water into a toilet tank under the control of a valve plug mounted on the end of a vertical axle having a float on its upper end. The valve plug is unseated, to admit water, when the axle is tilted, and the plug is pulled into seated position by the float when the tank is filled. A drainage buoy, in cooperation with a buoy base, allows discharge of water from the tank when the buoy is pulled from the base. Pull chains are used, from a toilet handle, to tilt the axle and pull the buoy. The inlet valve includes a water pressure reducer, and a non-return valve assembly to prevent return of water to the water supply in the event of a loss of water supply pressure.
