4.5 How to find Leaks with the AQUASCOPE 3 Tripod foot
The tripod foot is a pinpointing tool that attaches to the electronic
listening stick in place of the probe bars. It is used to find leaks in
concrete slab, shallow underground pipes and in walls.
It should
always be placed or held in a still position during operation.
1. Localise the leak position with noise loggers or an electronic listening
stick. If a Correlator is available this can be used to narrow down the
location to a much smaller area.
2. It is best practice to locate the pipe position with a pipe locator.
3. Follow the path of the pipe listening for the leak at 1 meter
intervals. Each sample should last long enough to capture a minimum
noise value, typically 20 to 30 seconds.
4. When the location with the highest minimum noise has been identified
use your leakage experience to confirm this is a leak noise.
5. Perform a “star check” moving about 30 cm from this point to all 8
points of a star. Each point should have a lower noise than the pin-
pointed leak position. If a point is louder this could be the correct
position, repeat the star check to verify.
