The Leak Detector allows you to have multiple custom frequency configurations. However, it's recommended
for beginners to take advantage of the PREDEFINED FILTERS offered with the unit. The next table can be used
as a reference depending on the job and conditions.
• Whenever possible, take measurements at a time when there is little external sound that may interfere
with
the
detection
(e.g. foot steps, machines that emit vibrations, people's conversations, road traffic, etc.)
• Do not move the ground microphone during measurements.
• Always take several measurements to better qualify the suspected point of the water leak.
• Check the pressure of the water network, using a manometer, the minimum pressure required with this
equipment is 55 psi (plastic pipes) and 20 psi (metal pipes), because you won't be able to hear any
distinctive sound from a water leak without this minimum pressure. Very important, the greater the
pressure on the water network, the deeper a water leak can be found in the supply network and the
easier it is to find its location.
Note: Make some test measurements to get used to the outside or external noises and repeat the process
several times on the point where a suspected leak is located, this will give you a better understanding of the
sound that the leak produces against external unrelated sounds.
