What should I do if my lead service line has been worked on (e.g., cut, repaired or replaced)?

If your lead service has been disturbed (e.g., worked on, cut, repaired or replaced), particles containing high levels of lead can become trapped in your home plumbing and lead levels in your drinking water may increase.

To avoid bringing lead-containing particles into your home or the tap water you drink, follow these instructions whenever your lead service line is disturbed:

  1. Locate the closest available tap to where the water comes into the home that is not used for drinking water (such as an outside hose bib, laundry sink or bathtub). It is key to pick the closest faucet not used for drinking. This results in the least number of particles and sediment coming into the home plumbing.
  2. Fully open the cold water tap and let the water run for at least five minutes to flush the lead-containing particles out of the plumbing so the particles and sediment do not enter the rest of your household plumbing.
