Want a quick, low-tech test? Fill a clear plastic bottle halfway with tap water. Add about five drops of pure liquid dish soap—not the fancy moisturizing kind. Put the cap on and shake it for 10 seconds.
If you get a massive, fluffy pile of suds, your water is soft and lovely. If you get a thin, sad layer of bubbles with a cloudy liquid underneath, you’ve got hard water. It’s the soap-equivalent of a party where nobody showed up.
The Corrosion Factor (Wait, What?)
Here’s a little-known nightmare: hard water can actually corrode metal pipes if the water is also acidic. But usually, it just coats everything in rock. Your water heater has to work harder to heat mineral-laden water, which can slash its lifespan by years.
Think of it this way: every time you run a hot shower, you’re slowly turning your water heater into a tombstone. It’s like paying a monthly rock tax.
