Why would you need a dual-tank water softener over a single tank?

The resin that attracts magnesium and calcium in salt-based ion-exchange water softeners must be replenished. In a single tank softener, such as NorthStar's NSC22, there will be times when the system will not soften the water, and it will only be regenerating. There will be no downtime with a two-tank system, such as NorthStar's NST30ED. While one tank is restoring, the other is softening.

But if most water softeners regenerate at night, why would you buy two tanks? When you buy two tanks, you use less water per day, which is more environmentally friendly. The water softener is still not working at full capacity when it regenerates every night. If you have a system with two tanks, you guarantee optimal efficiency (ion exchange).

And we should add that if less water is used, it means that cities are less likely to ban the use of water softeners.

How does the NorthStar water softener compare to other water softeners?
