MATERIALS VERIFICATION TEST

The Materials Verification Test below can help you figure out if you have a lead, galvanized steel, copper, or plastic service line on the portion of the service line you own. When you have completed the visual inspection, please submit your results using the following survey link. If you have a lead or galvanized steel service line, Middlesex Water will contact you to confirm the results and schedule your service line replacement.

What you need:

  1. House key or coin
  2. Strong refrigerator magnet

Steps to check your service line:

  1. Find the water meter in your basement or outside your home and look at the service line that enters the water meter.
  2. Use the house key or coin to carefully scratch the pipe surface.
  3. Compare the scratched area to the following descriptions:
    • If it looks shiny and silver, the pipe is made of lead. A magnet will not stick to a lead pipe.
    • If it is a dull gray color with no noticeable scratch on the surface, the pipe is galvanized steel. A magnet will stick to a galvanized steel pipe.
    • If it is the same color as a penny, the pipe is copper. A magnet will not stick to a copper pipe.
    • If it is smooth and red, blue, white, or black, the pipe is plastic. A magnet will not stick to a plastic pipe.
  4. Report your service line material in this SURVEY
