The invention is a unit (1) for intercepting the water flow in WC cisterns (C), of the type comprising: one on-off valve (2) having an inlet way (3) connected to a pipe (4) for conveying the water coming from a water supply network, an outlet way (5) connected to a pipe (6) for delivering water into the cistern (C), and a connection chamber (7) suited to place the inlet way (3) in communication with the outlet way (5); magnetically-operated means (8) for controlling the water flow between the inlet way (3) and the outlet way (5), comprising a rod (10) provided with a floating element (11), the control means (8) being arranged coaxial to the longitudinal axis (X) defined by the rod (10). The control means (8) comprise: a shutter (15), made of a paramagnetic material, suited to cooperate with the outlet way (5) during the opening and closing stage; a magnetic body (16) arranged outside the shutter (15) and mechanically associated with the rod (10), said magnetic body (16) being arranged at the level of the shutter (15) at least when the shutter (15) cooperates with the outlet way (5) during the closing stage.
