In apparatus for flushing a closet wherein the flushing liquid is in a closed circuit connected with the closet pan 10, an air pump 15, 16 transmits pressure to a reservoir of liquid to impel it into a flushing gallery 14, the reservoir being replenished after each operation of the pump 15, 16 through a non-return valve 11 connected with the pan 10 or with a sump communicating with the latter. The closet is flushed on closing a lid 19 to which is connected a lever 18, (although it may be integral with the lid), pivotally connected with the rod 17 of the piston 16 sliding in the cylinder 15, the outlet port 151 of which is connected to the pipe 12, constituting the reservoir connected at one end to the valve 11 and at the other end to the flushing gallery 14. - To admit air automatically into it on the return stroke of the pump the connection 121 between the port 151 and the pipe 12 has a non-return valve 20. The lever 18 may be a manually-operated arm, or a pedal, pivotally mounted alongside the closet.
