Gallons Calculation Tool
The control valve head uses a meter to count the gallons of water being treated through the system. Once the gallons
programmed in the unit have been exhausted, the system will regenerate. The total gallons of treatable water the system
can produce is based on the system size, family size, and the hardness level of the feed water. A simple calculation is
done to determine the amount of gallons to input during the "Setting 3" programming portion of the installation.
Total Gallons = System Capacity in Grains (see chart below). Hardness in GPG
(Grains Per Gallon) determined by water test - Number of People X 75 Gallons.

NOTE:
*
The optional brine tank overfill connection is not required since the brine well is equipped with an
automatic shutoff valve. If you want to utilize this feature, purchase and install a ½" plumbing hose
to this connection and run it to the drain.
Example:
System Capacity: PRO-S-80E
Feed Water Hardness: 25 GPG (must be tested on-site by the end user or installer)
Number of People:
4
(80,000 Grains / 25 GPG) - (4 People X 75 Gallons)
3,200 Gallons - 300 Gallons = 2,900 Total Gallons
2,900 Gallons would be inputted for Total Gallons during programming.
If the hardness level is given in ppm or mg/L, it can be converted to Grains Per Gallon by dividing the value by 17.1.
