An eductor (1) for mixing liquids, e.g. a concentrated solution into water, has a flow passage (16) for a first liquid into which a dispensing passage (18) for a second liquid opens so that in use the second liquid is drawn into the flow of the first liquid. The dispensing passage (18) including a flow restrictor portion provided by a groove (22) extending on the periphery of a restrictor plug (19) removably received in a socket (21) of the eductor body. The groove (22) and the wall of the socket (21) define the flow rate in the dispensing passage. The plug (19) has a plurality of the grooves (22) and is selectively insertable into the socket in a plurality of positions, the grooves providing respectively different flow rates of the second liquid.
