Find out if your water line is made from lead
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 |
