Abstract (en)
A non-gravity flushing system is provided, comprising a water inlet valve (108) for allowing pressurized supply water to enter said flushing system (100) being arranged in direct fluid communication with said water inlet valve (108), wherein said flushing system (100) is configured to discharge a flow of flushing water through an outlet port (302) into a water inlet of a WC bowl (10) when a flush is initiated. The system is characterized by a first backflow prevention device (150) arranged downstream of the water inlet valve (108), and a second backflow prevention device (350) arranged downstream of said first backflow prevention device (150) and upstream of the water inlet of said WC bowl (10).
