Step by Step Instructions

1. Find the water meter in your basement. Look at the pipe that comes through the outside wall of your home and connects to your meter.

2. Carefully scratch the pipe (like you would a lottery ticket) with a key or a coin. Do not use a knife or other sharp tool. Note: If pipe is painted, use sandpaper to expose the metal first.

3. Place the magnet on the pipe.

4. Take a photo of the scratched pipe and submit your results in this form.

Types of pipes

Lead pipe

A magnet will not stick to a lead pipe. Scratch the pipe with a coin. If the scraped area is shiny silver and flakes off, the service line is lead.  

Copper pipe

A magnet will not stick to a copper pipe. Scratch the pipe with a penny. If the scraped area is copper in color, like a penny, your service line is copper. 

galvanized steel

If a magnet sticks to the surface, your service line is galvanized steel. A scratch test is not needed. If you scratch the pipe, it will remain dull gray.
