PROBLEM TO BE SOLVED: To provide the pressurized water feeder of a water-jetting type loom in which structures of changeover valves are simplified, though pressurized water can selectively be fed to one of three or more terminal flow outlets and jetting water is stabilized. SOLUTION: The pressurized water feeder comprises at least first and second changeover valves for selectively feeding the pressurized water from a pressurized water-feeding source to either one of three or more terminal flow outlets including a plurality of weft-inserting nozzles and a driving apparatus for driving the changeover valve. The first and second changeover valves have each one water inlet and a plurality of water outlets. In the first changeover valve, the water inlet communicates with the pressurized water feed source and one of these water outlets communicates with the second changeover valve.
