• at least a vessel containing a softening substance;
• at least a distributor consisting of a manifold body associated to said vessel in which there are at least an inlet pipe for water to be treated, at least an outlet pipe for treated water and a plurality of inner ducts that can be intercepted through flow ways belonging to a spool sliding inside said manifold body;
• and least a control device comprising mechanical members adapted to control opening and closing of valves during the various operation stages of said softener;
• a control unit for programming execution of the operative cycles of said softener;
• at least an actuator unit comprising a cylinder fixed to said spool and sliding in a barrel whose volume is divided into at least a first chamber and at least a second chamber opposite to said first chamber, said actuator unit being adapted to move said spool to define different mutual positions of said flow ways relative to said inner ducts, each position being adapted to set different water paths;
• wherein said first chamber of said cylinder has at least one waydirectly communicating with said inlet pipe and said second chamber has at least a first water feeding way communicating with the inlet pipe through a valve and at least a second seeping way for water outlet.
