Homes built after 1950 are more likely to have copper service lines.
You can often identify the material used in your service line through a visual inspection at the point where the water service line enters your home. Reference this photo (PNG) to find the location.
- Find the section of plumbing that enters your home near the foundation, there is usually a valve at that location. Be careful not to confuse it with the sewer or gas line.
You can scrape a small section with a coin if it is dirty or discolored. Reference this photo (PNG) for pictures of pipe material types.
- If the scraped area is shiny and silver, your service line is lead. A magnet will not stick to a lead pipe.
- If the scraped area is copper in color, like a penny, your service line is copper.
- If the scraped area remains a dull gray, and a magnet sticks to the surface, your service line is galvanized steel.
- The plumbing material may be PEX / plastic. In this case, it would appear to be plastic, not metal.
