Fill a glass with hot water from your tap and another with cold. Let them both sit for a full five minutes. Now check the color and sediment settled at the bottom. Hot water usually leaches more metals from pipes, so if that glass looks rusty or has grit, you’ve got a clue about your plumbing’s condition. This test also reveals if you need to let the tap run before using water for drinking or cooking; you might just save yourself from drinking a little pipe dust.

The Boiling Test for Total Dissolved Solids
Boil a cup of tap water in a clean, white ceramic mug until it’s completely gone. Let the mug cool, then look at the bottom. A thin white powder isn’t a big deal—that’s mostly harmless minerals. A thick, crusty layer that’s hard to wipe off? That’s a sign of high total dissolved solids (TDS), which affects taste and scale buildup in your kettle. This simple trick gives you a visual report card on your water’s mineral load—no degree required.
