  4. Step One:

    Locate the water service line coming into the home or building. This is typically found in the basement. An inlet valve and the water meter are installed on the pipe after the point of entry. For this survey, we will be identifying the pipe material listed as "SURVEY AREA"  shown in the picture: "Water Service Line".

  6. Step Two:

    Use a key or the flat edge of a screwdriver to scratch through any corrosion that may have built up on the outside of the pipe. DO NOT use a knife or other sharp object to do the scratch test and take care not to puncture a hole in the pipe. 

    Compare your findings to the illustrations below.
