  • Twin alternating water softeners are ideal for situations where uninterrupted and continuous flow of soft water is a necessity. One of the two resin tanks is always in service, while the other tank is on standby. When the softening capacity is reached in resin tank #1 the Fleck 9100 Meter Control Valve will switch the tank from standby to service for resin tank #2. The tank containing the exhausted resin in tank # 1 will be regenerated and set on standby until the other tanks’ capacity is reached and is ready for regeneration.
