An airless spray painting system wash-out apparatus is provided to facilitate cleaning of fluid transfer pump and other components. A wash-out apparatus or element is adapted for temporary or permanent insertion between a liquid source pick-up point and where the fluid may exit the system. The wash-out element includes a body portion, a flow valve, and a wash-out hook-up valve. The flow valve is operable to control the flow of fluid from a first hose into or through the body. A wash-out hook-up is provided to couple the body of the wash-out apparatus to a cleaning fluid source or supplying line. A wash-out hook-up valve is provided to control the flow of fluid between the body and the wash-out hook-up. Alternatively, the flow valve and wash-out hook-up can be arranged within the pump housing to permit cleaning fluid to pass through and cleanse all parts of the wash-out apparatus.
