What is the difference between a “demand” type water softener and one on a timer?
The demand-type water softener will only regenerate based on your water usage. The timed-clock water softener will regenerate on a pre-set schedule whether it needs to, or not. This will result in excess salt consumption, excess brine water pumped into your septic tank or sewer system, and over softened water. APEC only sells the demand-type of water softeners.
