Abstract
The water softening system hereof employs a treatment tank containing a mineral bed of ion-exchange resin granules, a brine tank, and a valve for periodically cycling water through the mineral bed for removing hardness and other undesirable factors therefrom, then passing a diluted brine solution through the bed in an opposite direction to its normal service flow to recondition and flush the bed. The control for the system includes electrically operated solenoid diaphragm valves, and a plunger valve responsive to water pressures, for controlling and regulating the flow of water and brine through the mineral bed. A venturi aspirator is incorporated in the plunger valve, whereby a saturated brine solution is drawn and with controlled dilution is caused to flow in a direction opposite to service flow through the mineral bed.
