From the information listed above, it should be clear that leak
sound travels well in metallic pipe and not very well in plastic
pipe. Once leak sound is detected, treat the leak as a "known
leak" and listen at several access points to determine the
approximate location and where to place the transducers for
pinpointing with the correlator.
6.2 TRANSDUCER CONTACTING METHODS
The S30 provides two different methods of contacting these
access points.
1.
Magnet - to attach the transducer to iron or steel
access points (e.g., valve operating nut).
2.
Extendable Probe Rod - The rod can be made up for
17", 33" or 49" length to reach valves or curb stops
below which may be buried or under water. Simply
attach the magnet to the Wave Guide, followed by the
rods to make up the desired length. See diagram
below.
