Identifying the Source and Testing Your Service Line

Serving Chicago, Park Ridge, Des Plaines, and the Northwestern Suburbs.

Are you concerned about lead in your drinking water? The best way to find out is to have your water tested, but there are signs you can look for to determine if you might have a lead service line.

There are several potential sources of lead in your home plumbing. 

  • Lead Service Line connecting the water main to your house.
  • Old solder in your plumbing.
  • Older brass faucets and valves.


How to Check Your Service Line

To check your service line, you can start by finding your water meter in the basement and look for the pipe that runs from the meter through the outside wall of your home. Lightly scratch the pipe with a key or coin (not something sharp) and if the scratch turns silver, it could be lead. If the pipe is painted, you may need to use sandpaper to reveal the metal. Finally, place a magnet on the pipe. If it sticks, the pipe is steel (lead is not magnetic).

If you are unable to see the service line, you may have to check utility records or dig it up to determine the material. Green Tech Plumbing, based in Des Plaines, IL and serving the Northwestern Suburbs of Chicago, is available 24/7 to provide a free estimate for lead service line replacement. Call 847-518-5338 or email us to get started.
