The valve of claim 3 wherein the manual control is rotatable in either direction through the first, second, third and fourth positions. 6. A valve for fastening to a water faucet disposed over a drain comprising: a valve body having a first connection adjacent the top thereof for connecting to a faucet;the valve body having a second connection for connecting to a reverse osmosis unit to provide faucet water from the valve to a reverse osmosis unit;the valve body having a third connection for receiving product water from a reverse osmosis unit;the valve body having a first outlet adjacent the bottom thereof for allowing a stream of water there through;the valve body having a valve member assembly therein for coupling the first connection to the first outlet adjacent the bottom of the valve body when in a first position, for coupling the first connection to the second connection when in a second position, for coupling the first connection to the second connection and for coupling the third connection to the first outlet when in a third position, and for blocking water flow through the first and second connections when in a fourth position;wherein the position of the valve member assembly within the valve body is controlled by a manual control accessible from a side of the valve body and rotatable about an axis thereof; andwherein the valve member assembly comprises a rotary valve member and an axial valve member coaxial with the rotary valve member and with a spring there between, which valve member assembly in cooperation with the valve body forms a combination rotary valve and axial valve. 7. The valve of claim 6 wherein the valve member assembly is rotatable with respect to the valve body about an axis of the valve member assembly to selectively align with openings for coupling the first connection to the first outlet adjacent the bottom of the valve body when in the first position, for coupling the first connection to the second connection when in the second position, for coupling the first connection to the second connection and for coupling the third connection to the first outlet when in the third position, and for blocking water flow through the first and second connections when in the fourth position, the third connection being coupled to a port coaxial with and at an end of the valve member assembly, the axial valve member being axially translatable and held in a position to block flow through the port by the spring, the valve body further having at least one cam surface and the axial valve member having at least one cam follower surface, the cam surface and cam follower surface engaging when the valve member assembly approaches the third position to move the axial valve member axially against the force of the spring to open the flow through the port to dispense product water. 8. The valve of claim 7 wherein the valve body further comprises a second outlet adjacent the bottom thereof, the second outlet providing a spray of water when coupled to the first connection, the valve member assembly in the valve body having a fifth position for coupling the first connection to the second outlet when in a fifth position. 9. The valve of claim 8 wherein the valve member is manually adjustable in either direction through an order of the first, second, third and fourth positions. 10. The valve of claim 8 wherein the valve body further comprises a second outlet adjacent the bottom thereof and concentric with the first outlet, the second outlet providing a spray of water when coupled to the first connection, the valve member in the valve body having a fifth position for coupling the first connection to the second outlet when in a fifth position. 11. The valve of claim 10 wherein the valve member is manually adjustable in either direction through an order of the first, fifth, second, third and fourth positions. 12. The valve of claim 10 wherein the valve body further comprises a fourth connection for coupling to a waste water outlet on a reverse osmosis water filter and a third outlet adjacent the first and second outlets, the fourth connection and the third outlet being in fluid communication and not controllable by the valve. 13.
