Water Line Repair in St. Louis: questions

How can I tell if my St. Louis service line is lead?

Check the city’s records and look at the pipe entering the basement before the meter. Lead is soft, dull gray and shiny when scratched, and a magnet won’t stick to it.

Will St. Louis replace my lead line?

The city has been working on replacement; check current program terms for your address.

Is my water safe with a lead line?

Use a certified filter for drinking and cooking, and flush taps after water sits, until the line is replaced.
