If your water has been sitting in the pipes for a few hours (say, overnight), flush the system. Run the cold water for at least one to two minutes before using it for drinking or cooking. This isn’t a dance move—but feel free to wiggle while the water runs.
Only use cold water for drinking and cooking. Hot water dissolves lead faster than a gummy bear in a sauna. So, no boiling your kettle from the hot tap, okay? Your tea will taste just fine.
And here’s a pro tip: flush each tap separately. Don’t just do the kitchen sink and call it a day—your bathroom sink has feelings, too.
