Honestly, you don’t need to obsess over it. Once a month, take a peek at the salt level and listen for the gurgle. If you’ve got a demand-based system, trust it. It’s smarter than you think.
But if you’re a control freak (like me), you can adjust the settings. Most softeners have a dial or digital menu where you can tell it how hard your water is. The harder the water, the more often it regenerates. It’s like telling your softener, “Hey, we’re in a tough neighborhood, work a little faster.”
