Wall vent and flushing method using same

Abstract

A venting outlet () for a drinking water supply system of an aircraft is proposed, having an inlet opening () which is arranged on a rear side of the venting outlet and is intended for receiving a venting fluid, in particular air, from the drinking water supply system, and further having a venting opening () arranged on a front side of the venting outlet and intended for discharging at least some of the received venting fluid to an external surroundings of the venting outlet (). According to the invention, the venting outlet () further comprises a flushing connection () and a cover () which can be mounted on the flushing connection () and can be removed therefrom and which has at least one through-hole (), wherein the venting opening () is formed by the at least one through-hole () in the cover () mounted on the flushing connection (), and the flushing connection () is designed, only with the cover () removed from the flushing connection (), for coupling a flushing fluid line () on the front side of the venting outlet and for introducing a flushing fluid, in particular drinking water, through the flushing connection () to the inlet opening () of the venting outlet. Also proposed are a wall element having the proposed venting outlet and a flushing method for a drinking water supply system with use of the proposed venting outlet.
