A flushing syphon assembly (1) incorporating an inverted generally U shaped duct (11) having an upleg (2) and a downleg (3), an open-ended chamber (4) fluidly connected to the upleg (2), a syphon piston (5) movable in the chamber (4) and a piston rod (7, 107) connected at one of its ends to the syphon piston (5) and at the other of its ends to an actuator piston (60, 160) of a power-driven actuator (6). The actuator (6) includes an inlet (63) that receives mains water for driving movement of the actuator piston (60, 160), thereby to lift the syphon piston (5) within the chamber (4) in order to initiate a syphonic flushing action. The supply of mains water to the inlet (63) of the actuator (6) is controlled by an equilibrium valve (101), which is activated by a push button activator (8). The equilibrium valve (101) is connected to the mains water source by a branch element (92, 192) of an inlet valve (9, 109). |
