ABSTRACT:
This invention relates to a sequencing valve for distributing fluid from an inlet selectively to one or more of a plurality of outlets in response to pressure variation in the source fluid. The improvement provides a manual means for advancing the valve mechanism without water pressure to select a particular outlet. The improvement further provides means to inactivate the sequencing mechanism so that the inlet source will remain connected to the selected outlet irrespective of pressure changes in the source fluid.
