How to Test Your Water Service Line

Find where the service line enters your home.  Test the pipe to see if a magnet sticks to the pipe.  If not, scratch the pipe with a penny to determine color.  Follow the instructions below.  To check if your water service line is in our inventory, click here.

Galvanized Steel Pipe

If a magnet sticks to the surface, your service line is galvanized steel.  A scratch test is not needed.

 

 

 

 

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.
