A water outlet for a low pressure sanitary outlet fitting, said water outlet comprising: a perforated structure element having a perforated structure that has a plurality of flow holes, and retains water in an outlet direction of the water outlet when the water outlet is in an unpressurized state; at least one bypass that bypasses the perforated structure and has an opening cross section that is larger than that of one of the flow holes; and a bypass valve, that is movable from a closed position in which it closes off said bypass, into an open position counter to a resetting force as a consequence of an increase in pressure on an inflow side of said water outlet, wherein the perforated structure element is configured with respect to the bypass so that the perforated structure element is permeable to air external to the water outlet in a direction counter to the outlet direction when the bypass valve is in the opened and closed positions.
