Guide to Identifying Your Service Line Material

Understanding what type of service line connects your home to the public water system is important for maintaining safe drinking water. Here’s a simple guide from Southington Water Department to help you identify the material of your service line using visual and practical tests.

Step-by-Step Process for Identifying Your Service Line Material

  1. Locate the Water Line
    Begin by finding where the water line enters your home. This is usually found in the basement, utility room, or near the water meter.

  2. Observe the Color
    Take note of the color of the pipe entering your home. This is one of the first clues to identifying the material.

  3. Perform a Scratch Test
    Gently scratch the surface of the pipe using a coin or a flathead screwdriver. Observe the color and texture of the scratch to determine the material.

  4. Use a Magnet
    Hold a magnet to the pipe and see if it sticks. This can help further distinguish between materials.

  5. Compare Your Findings with the Key Below
    Match the characteristics of your pipe to one of the descriptions below to identify the material.
