A system for ventilating a toilet having a cistern and a bowl includes a valve located between the cistern and the bowl. The valve includes a housing having a top surface, a bottom surface, a through-passage extending from the top surface to the bottom surface, and a ventilation passage provided at an angle with respect to the through-passage. The through-passage is located at an interior of the housing and is in fluid communication with the bowl. The ventilation passage has an inlet at the interior of the housing and an outlet at an exterior of the housing. A vacuum source is connected to the outlet of the ventilation passage and configured to establish a negative pressure in the ventilation passage to draw air from the bowl through the through-passage, and to exhaust the air to a remote location. The housing, through-passage, and ventilation passage are integrally formed. |
