manufacturer’s limited product warranty.
•
Efficiency rating means the percentage of the influent water to the system that is available to the user as
reverse osmosis treated water under operating conditions that approximate typical daily usage.
•
Recovery rating means the percentage of the influent water to the membrane portion of the system that
is available to the user as reverse osmosis treated water when the system is operated without a storage
tank or when the storage tank is bypassed.
