Try this in your kitchen sink: fill it with water and add a squirt of dish soap. In hard water, you’ll get weak, sad bubbles that disappear fast. Soft water? You’ll get a fluffy mountain of suds.
It’s like comparing a polite clap to a rock concert. If your soap is frothing up like crazy, your softener is probably doing its job. If not, well, maybe it’s on a coffee break.
The Hardware Check
Feel your bathroom faucets and showerheads. Hard water loves to build limescale—that white, crusty stuff that looks like a fossilized coral reef. After a few weeks with a softener, that crust should start to dissolve or at least stop growing.
Run your finger inside the toilet tank or under the faucet. If it feels gritty or rough, you’ve got hard water residue. If it’s smooth as a dolphin, your softener is winning the battle.
