I learned this from a plumber who smelled like sawdust and wisdom. Fill a clear glass jar with tap water, then let it sit on the counter for 24 hours. Do not cover it. This is like a little science experiment for your kitchen.
How to Test Water With a Home Water Test Kit
After a day, check the bottom. If you see a layer of white flakes or sediment, you’ve got hard water—calcium and magnesium partying in your glass. If the water turned cloudy or has a film on top, you might have organic matter or bacterial growth. It sounds gross, but it’s just information. You’re now a water detective!
The $15 Fix: DIY Test Kits
For the truly curious (and slightly impatient), buy a home water test kit. You can find them at most hardware stores or online for about the price of two fancy coffees. These kits come with little strips that look like pregnancy tests—you dip them in water, wait a minute, and compare colors.
I did this last week and discovered my water has moderately high pH and a touch of iron. The test strip turned a shade of pink I’d only seen on flamingos. It was weirdly satisfying. You test for hardness, chlorine, pH, nitrates, and even lead. It’s like a report card for your faucet.
