DESCRIPTION

The BIG THUMPA has been developed and built-in Australia. It generates a noise in the water pipe which can easily be picked up with the use of an acoustic listening device. This pulse or thump can be detected at depths well over a meter. In fact we have heard the noise more than 9m (30') from the pipe and traced a 6" main for over 300m or 1000' in distance. These distances will vary slightly depending on the soil type. 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.

power source

As with the smaller version, the Big Thumpa requires 12v power and we recommend using your own 18v cordless tool battery with one of our adapters fitted with a 12v outlet socket and USB outlet for charging your phone. We have adapters for Milwaukee 18v and 12v, Makita, Hitachi, Dewalt, Bosch, and Metabo. We also have Lithium Iron Power Banks which can do the job but shipping restrictions make them not possible to send by air freight. If you don’t use any of these brands, please make an inquiry and we can work out another option.
