Locating Cast-Iron Pipes

 

 
Cast-iron pipes produce the strongest magnetic signals at their joints. 

 

Figure 17:  Signal Patterns Provided by Cast-Iron Pipes 

 

 
 
After an initial sweep search identifies the general direction of the pipe, the steel pipe joints or 
transition points can be more accurately traced by the following procedure: 

 

1.  Set the sensitivity control to maximum (#5). 

 

2.  Hold the locator vertically approximately 1 to 1-1/2 feet above the surface. 

 

3.  Walk without turning or tilting the locator. 

 

4.  Mark the locations where the maximum signal levels occur. 

 

5.  Return to an area of maximum signal  strength and hold the locator several inches 

above the surface.  The sensitivity will probably have to be reduced during this second 
pass.  Four-inch pipes can be located at depths of up to 10 feet.
