Appendix A: Maximum Deployment Distances
The maximum permissible distance between deployed loggers varies
according to the pipe material. Refer to the following table to determine the
maximum distances. Do not exceed these distances.
Pipe Material Maximum range
Asbestos Cement 4593 feet (1400 m)
Cast Iron 5906 feet (1800 m)
Concrete 5577 feet (1700 m)
Copper 5906 feet (1800 m)
Ductile Iron 5906 feet (1800 m)
Ductile Iron (concrete-lined) 5906 feet (1800 m)
Galvanised Iron 5906 feet (1800 m)
HDPE (high-density poly) 1640 feet (500 m)
Lead 3281 feet (1000 m)
MDPE (mid-density poly) 1640 feet (500 m)
PVC 1640 feet (500 m)
Steel 5906 feet (1800 m)
Note: Please note that these are only maximum distances. The actual
distance the leak noise travels varies based on the pressure, pipe
diameter, wall thickness, and amount/frequency of noise generated by
the leak. Therefore, ADS provides no guarantee that the leak noise
will actually travel the maximum distance referenced in the table
above.
