Vacuum breaker comprises a body (11) and a cover (12) which cooperate to define a cavity (13), the body (11) being integrally formed with an inlet pipe section (14) which defines a water inlet and an outlet pipe section (15) which defines a water outlet, the cover (12) being formed with an air port (16), wherein a tip portion of the inlet pipe section (14) extends into the cavity (13) in a direction towards the air port (16). The length of the tip portion of the inlet pipe section (14) which extends within the cavity (13) is greater than half of the height of the cavity (13), to elevate the level of the water inlet in order to raise the CL (critical level) line in the cavity (13). |
