A home water test shows how hard your water is, meaning how much dissolved mineral it carries, before you ever see scale on a faucet. This clip walks through a drop-reagent test from sample to reading.

Water runs from a kitchen faucet into a stainless sink to collect a sample. Then a SwiftPro tech in a black hoodie kneels beside a water heater in the utility room with a drop-reagent test kit.
The steps on screen are the whole method: collect the sample, add the reagent, watch the color change, read the hardness. With a drop test, the number of drops it takes to change the sample's color gives the reading, usually in grains per gallon.
Testing next to the water heater makes sense. That's the appliance hard water hits hardest.
A basic test like this one measures hardness, the calcium and magnesium in your water. Fuller tests add chlorine, pH, iron and dissolved solids, and well water tests check for bacteria too. If you're seeing scale, stains or an odd taste, a test tells you the cause instead of leaving you to guess at products.
