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.

You’ll need a coin and a magnet.

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
