Capacity of a Water Softener

How many gallons a softener will approximately make depends on the hardness of the water source and your water usage. If you go too long before performing the regeneration process a few things may happen: your unit may not last very long, or, after the regeneration process, the strips will not test between 0-2 GPG at the output of the softener. This can easily be corrected by performing a special regeneration process.
