Device for controlling a water distribution system, the device having, in a manifold (11) with connectors (13,15,16,17,21) for connecting to at least one pump (14), at least one user, at least one expansion tank (18) that operates the control circuit of the pump, and at least one pressure switch (20), and having a seat (23) in which a position-indicating element (25) is guided so that it slides in one direction under the thrust of the discharge flow of the pump and in the other direction under the thrust of an elastic contrast element (29); the position-indicating element (25) cooperates with an external transducer (31) which is connected to the pump control circuit that is activated/deactivated thereby. The connector (15) for at least one user ends in the region where the position-indicating element slides. <IMAGE> |
