A valve assembly for an engine, the valve assembly can include a housing; an in-flow port configured for connection with a drain line; a first out-flow port configured for connection with a fuel line; a second out-flow port configured for connection with a disposal line; and a passageway that is rotatable with a handle, the passageway being operable to redirect a flow of a fluid between the fuel line and the disposal line. The handle is configured to impede an attachment of the fluid source to a water wash connection when the passageway is in a position to direct the flow of the fluid from the drain line to the fuel line.
