Abstract
An electric control for a water conditioning system includes a solenoid valve which controls water inlet into the system and which is controlled by a flow switch that senses product water flow from a water faucet or other outlet. The flow switch also energizes an indicator lamp for indicating processing of water. The flow switch also controls a second solenoid valve which allows water flow into the pressure or "squeeze" side of a bladder type product water storage tank. When product water flow occurs, the second solenoid valve opens to permit supply water to flow therein, providing additional pressure to the product water side of the storage tank. Accordingly, product water flow is effected from the storage tank to the product water outlet. When a predetermined low pressure is sensed, a pressure switch located on the product water side of the storage tank opens the first solenoid valve to supply water to the system for processing. Also, the solenoid valve which provides squeeze water to the storage tank is closed, thereby permitting product water to flow into the storage tank and accumulator. When a predetermined high pressure is sensed by the pressure switch, the first solenoid va…
