A mixing unit for mixing first and second fluids, comprising: a housing having an inlet for the first fluid, an inlet for the second fluid, and an outlet for a resultant fluid from any flow of first or second fluids, or both; a flow control member within the housing having at least a substantially spherical zone having dedicated for each of the fluids (i) an inlet port, (ii) a passageway leading from the inlet port to (iii) an outlet; and sealing means between the flow control member and the housing. In use, the flow control member can be rotated to allow issuance of no or either or both fluids from the housing outlet. Prior to the housing outlet outletting the flow from both passageways (if both) of the flow control member, one flow will have exerted past its passageway outlet a venturi draw in effect on the flow of the other.
