The system (10) comprises: a water and/or air inlet (20), which can be connected to a water supply pipe (5) for a sanitary apparatus (1); an outlet (40), which can be connected to a sewage outlet pipe (4) downstream of the sanitary apparatus (1); and a suction box (30), to which said inlet (20) leads and from which said outlet (40) starts. The suction box (30) comprises a motorized ventilation device (31), for conveying air from said inlet (20) to said outlet (40), and a siphon (32), which is at least partially filled with water (33) coming from the water supply device (6). The ventilation device (31) and the siphon (32) are mutually in series between the inlet (20) and the outlet (40). The suction box (30) comprises a further siphon (321), which can be connected between the supply pipe (5) and the outlet pipe (4) and is arranged in parallel with respect to the siphon (32) and the device (31). The further siphon (32') is at least partially filled with further water (33'), which tends to become stagnant in the supply pipe (5) upstream of the sanitary apparatus (1). |
