If you want a number instead of a guess, grab a water hardness test strip from your local hardware store or online. They’re cheap, easy, and come with a color chart that makes you feel like a water detective. Dip a strip in a glass of tap water for a few seconds, then compare the color change to the chart.
These strips measure the exact parts per million (ppm) of calcium and magnesium. Under 60 ppm is considered soft, 60–120 is moderate, and over 120 is where things get crusty. My neighbor did this and discovered his water was a stunning 200 ppm—he called it “liquid rock juice” and finally understood why his dishwasher was struggling.
What your faucet tells you
Look at your bathroom faucet or showerhead. Those white, flaky deposits that are a pain to scrub off? That’s hard water leaving its calling card. If you see a buildup that looks like a miniature stalactite, your water is definitely hard. It’s nature’s way of decorating, but not in a good way.
I once cleaned my showerhead with vinegar and a toothbrush, only to find a tiny, solid tube of scale inside. I thought, “Ah, so that’s where my water pressure went.” It was oddly satisfying to remove, like picking a stubborn sticker off a new phone.
