Your water softener control valve should be set precisely to match your home's raw water hardness rating measured in grains per gallon (gpg). To determine this number, test your incoming unsoftened water using a digital test kit or review your municipal water report. If your test reads parts per million (ppm), multiply that value by 0.0584 to convert it into grains per gallon, then enter that exact figure into your softener's programming menu. Setting the hardness correctly ensures the system regenerates based on actual usage rather than guesswork. Verification: Check your user manual and verify that your control valve is programmed using grains per gallon.
