If your home or business had water service before 1987, you could have a lead service line. This could be true even if it’s been remodeled.
If your home or business was built with a new water connection after 1987, you do not have a lead service line. If the water connection existed before the building was constructed or remodeled, there’s a chance the service line could be made from lead.
Before you start
You’ll need a coin and a magnet.
What to do
1. Locate where the service line comes into your home or business
This is usually near the main shutoff valve.
2. Look for a test area
The test area is a part of the pipe between the wall or floor and the shutoff valve.
3. Conduct scratch and magnet tests
Gently scratch the surface of the pipe with a coin. Then hold the magnet against the pipe and see if it sticks.
4. Compare your results
|Pipe material||Scratch test||Magnet test|
|Lead||Pipe is soft and easily scraped. The scratched area is shiny and silver.||Does not stick|
|Copper||Scratched area is copper colored, like a penny.||Does not stick|
|Galvanized||Scratched area remains gray.||Sticks|
Take the water line survey. Even if you don't think your water line is made from lead, please complete the survey. This will help us identify lead service lines faster.
