The optional hand-probe tripod attachment is used to find leaks buried
in concrete slab, walls and shallow ground. Attach to the tripod foot, lift
or move the hand-probe to each point and then listen.
The following photos show example methods of using the

6.4 How to find Leaks with the AQUASCOPE 2 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.
4. When the location with the highest 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.
