The flushing process
Crews will perform an important process called flushing to remove any remaining lead particles from inside the pipes. The contractor will leave steps for how to flush the rest of the house to remove any remaining lead particles. The process is very important and involves running ALL taps inside the house for at least 30 minutes to flush out the lead.
After flushing, the EPA strongly encourages customers to use a filter certified to meet the NSF 42 and 53 Standards for removing lead in the pipes for drinking and cooking water for 6 months after the service line is replaced. The EPA also recommends that you clean out all aerators on the ends of your faucets and periodically run your water to remove any collected lead particles. Your utility will offer to sample your water 3 to 6 months after replacement to confirm low lead levels.
