turncock वाक्य

McPhee towed the vessel to England, finding on the way that someone, probably disgusted at the squalid conditions aboard and preferring to abandon ship, had purposefully opened the turncocks and flooded the engine room.
A cottage was erected alongside the tank on the vacant piece of ground shortly after the tower was opened so that the turncock would live on the premises and give every attention to see that the tank was constantly well filled with water.
