Pellet salt designed for water softeners that is 99.6% pure or more is the best to use for your softener. Un-pure salts, such as solar or rock salt, may cause a salt bridge (thick block of salt) in the brine drum or may clog up the system with debris. This will cause your system to work inefficiently or to malfunction causing you to experience hard water.
If you are in need of a salt fill up, Haferman does offer salt sales in our store or delivery where we will test your water to confirm all is well with your system. We also offer fill up reminders. Contact us to learn more.
