Open the salt tank—the white bin where you dump those bags of salt pellets. If the salt level dropped drastically overnight, the softener definitely regenerated. It uses about one pound of salt per regeneration, depending on hardness levels. So if you see a big hole in the salt like someone took a giant scoop out of a snow cone, you’ve got your answer.
Surprising fact: your softener eats salt like a teenager eats pizza. A typical family of four can go through 40–50 pounds of salt per month. That’s about the weight of a small, very hungry dog. If you never add salt, your softener will eventually give up and just let hard water flow through. It’s basically a rebellion of inanimate objects.
The “Cup Test” DIY Detective Move
Here’s a low-tech trick that makes you look like a plumbing Sherlock Holmes. Fill a clear glass with water from your kitchen sink. Add a few drops of liquid soap—not dishwasher soap, the hand-washing kind. Shake it like you’re making a martini at a bad party. If you get thick, fluffy suds that last forever, your water is soft. If you get sad little bubbles that disappear instantly, your water is hard, and the softener hasn’t regenerated.
Humorous twist: I did this once and got so many suds my glass looked like a cloud factory. My friend thought I was doing science. I told him I was just proving my water softener isn’t a lazy liar.
