Fuel drain valve for a turbine engine

A valve assembly for an engine (113), the valve assembly (201) can include a housing; an in-flow port (219) configured for connection with a drain line (203); a first out-flow port (221) configured for connection with a fuel line (205); a second out-flow port (223) configured for connection with a disposal line (213); and a passageway (215) that is rotatable with a handle (207), the passageway (215) being operable to redirect a flow of a fluid between the fuel line (205) and the disposal line (213). The handle (203) is configured to impede an attachment of the fluid source to a water wash connection (209) when the passageway (215) is in a position to direct the flow of the fluid from the drain line (203) to the fuel line (205).
