WATER SOFTENING SYSTEM 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 un- desirable factors therefrom, then passing a diluted brine so- lution 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 dia- phragm valves, and a plunger valve responsive to water pres- sures, for controlling and regulating the flow of water and brine through the mineral bed. A venture aspirator is in- corporated 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.
