Got a letter saying your line is lead or unknown?

Utilities must notify every home with a lead, galvanized-requiring-replacement or unknown line. Here's what to do first:

  1. Check the pipe yourself where it enters the house.
  2. Filter drinking and cooking water with an NSF/ANSI 53 lead-certified filter.
  3. Test your water through your utility or a certified lab.
  4. Ask your utility about free replacement, or get plumber quotes.

Get replacement quotes

Enter an email or a phone number. Check first whether your utility replaces the line for free; many do.
