If you have only a helical pipe made of a non-conducting material (fibreglass,
PVC, etc.), we suggest inserting a metal wire having a cross section of
approximately 1.5mm2 in the non-conducting helical pipe
When the line is traced, the place at which the signal received by the receiver
falls off suddenly is the location of the constriction.
Refine the detection by setting the power level transmitted by the
transmitter and the sensitivity of the receiver in manual mode.

DETECTION OF A METALLIC WATER SUPPLY AND HEATING PIPE

Preconditions:
The pipe must be conducting, and so metallic (for example galvanized steel);
The pipe to be detected must not be earthed. There must be a relatively high
resistance between the pipe and the ground (otherwise, the detection
distance will be very short);
Connect the transmitter to the pipe to be detected and to earth.

Remarks:
The transmitter must be earthed at a certain distance from the pipe to be
detected. If the distance is too short, the signals and the circuit cannot be
located precisely.
