Your water softener control valve should be programmed precisely to match your home's raw water hardness rating measured in grains per gallon (gpg). To determine this setting, test your incoming unsoftened water using a digital test kit or review your local municipal water quality report. Multiply your test result (in milligrams per liter or ppm) by 0.0584 to convert it into grains per gallon, then input that exact number into your softener's programming menu. Setting the hardness correctly ensures the system regenerates at the proper interval. Verification: Check your owner's manual to ensure your control valve is programmed using grains per gallon rather than parts per million.
