Water Line Repair in Chicago, IL

Water Line Repair in ChicagoWater service line work in Chicago is dominated by lead. Because the city required lead service lines until 1986, many homes still have one, and a leak, a renovation or a new water meter often raises the question of replacing it. The city has a long-term lead service line replacement program, so it’s worth checking eligibility and city records before paying for private replacement.

Water Line Repair in Chicago: questions

How do I check if my Chicago home has a lead service line?

Look up your address in the city’s lead service line records and inspect the pipe entering the basement before the meter: lead is soft, dull gray and shiny when scratched.

Should I filter my water if I have a lead service line?

City guidance recommends using a filter certified to NSF/ANSI 53 for lead reduction until the line is replaced, along with flushing taps after water sits.
