QR Code Link to This Post
The LITTLE THUMPA has been developed and built-in Australia. It generates a pulse or a noise in the water
pipe which can easily be picked up with the use of an acoustic listening device. This sound can be detected
at depths well in excess of 1m and for for more than 100m in length depending on the soil type. It is suitable
for domestic pipes up to 50mm in diameter although it has been used on larger pipes with some success.
The water flow through the device is minimal but enough to generate a very loud thump.
The Thumpa is fitted out with a brass female click-on tap connector and a brass male connector underneath
enabling a waste hose to be attached to drain away used water. The device is water-resistant so if there's
a leaky valve on the tap with water running everywhere it will have no effect on the thumper's performance.
All electronics inside the case are sealed in resin making the unit very reliable.
POWER SOURCE
The Thumpa requires 12v power, the unit comes with Milwaukee 18v adapter. Other adapters can be ordered online.
The Big Thumpa is suitable for water mains over 50mm in diameter. The water flow through this device is significantly
more than the Little Thumpa. The device is fitted with a tough 1” or 25mm stainless cam lock coupling and a
brass male connector underneath enabling a waste hose to be attached to drain away used water. The device
is water-resistant so if there's a leaky valve on the tap with water running everywhere it will have no effect on the
thumpa's performance. All electronics inside the case are sealed in resin making the unit very reliable.
You can pickup the thumping sound on pipes with your listening device then mark out the line above ground.
