Here’s a secret: lead loves to party in stagnant water. If you test a sample from a running tap, the lead might be diluted and hide from you. So we need to be sneaky.
Let your water sit still in the pipes for at least six to eight hours. Overnight works perfectly. Don’t use any water during that time—no flushing, no showers, no sneaky sips for your thirsty houseplant.

This ensures any lead that leached from pipes or solder concentrates in your sample. It’s like setting a trap for lead. You’re basically a water detective now.
Step Three: Collect Your Sample Like a Pro
First thing in the morning, grab a clean glass or the container that came with your kit. Don’t run the tap. Just open it and collect the first water that comes out. That’s your first-draw sample.
Fill it exactly to the line your kit specifies. Overfilling makes the test inaccurate, and underfilling is just sad. Use a steady hand—no shaky coffee jitters allowed.
If you want to be extra thorough, also take a sample after letting the water run for 30 seconds. This tells you if your pipes or the city supply is the culprit. Two tests, one coffee date.
