Replace old household plumbing and potential lead sources. Replace galvanized plumbing with copper pipes and install "lead-free" plumbing fixtures that contain 0.25 percent lead or less. After installation, flush cold water taps for five minutes once a day for three days. Read our guide to identifying household plumbing for more information.
