hardness of your water supply, in grains per gallon.
The default is 25.
NOTE: If your water supply contains iron

number. For example, assume your water is
20 gpg hard and contains 2 ppm iron. Add 5
to the hardness number for each 1 ppm of
iron. In this example, you would use 30 for
your hardness number.
