Abstract: A water distribution apparatus employs a self-positioning water flow actuated rotor for serially channeling water flow into each of a plurality of outlet conduits from a common source of water under pressure. The rotor, housed within an encapsulating cavity, includes a hollow hub closed at an end and having the other end in fluid communication with the source of water under pressure. A plurality of jets eject water from within the hub intermediate a pair of hub mounted discs and provide motive power for rotating the rotor. Opposed apertures in the discs provide fluid communication between the jets and serially with a selected pair of opposed outlets connected with one of the outlet conduits; the rotational positioning of the rotor corresponding with a pair of outlets is regulated by a timed solenoid.
