A water-testing apparatus tests an article such as a turbine airfoil component having at least two water flow passage article inlets. The apparatus includes an apparatus body having a water inlet, and an attachment head integral with the apparatus body. The attachment head includes a holder that receives the article therein in sealing contact with an article seal, and at least two ports, each port being in registry with at least one of the at least two water flow passage article inlets. A water flow controller within the apparatus body has a controller inlet in water-flow communication with the water inlet, at least two controller outlets, each controller outlet being in water-flow communication with one of the ports of the attachment head, and a flow-control valve disposed in a water flow path between the controller inlet and the controller outlets. The flow-control valve is controllable to controllably connect a single one of the controller outlets at a time to the controller inlet.
