Скачать или смотреть Thumper (water pipe locator)

Locating underground plastic water pipes, especially on large or older properties is not easy and very time consuming. Locating plastic water pipes in a lot of situations, cannot be done without either inserting some foreign metallic object up the pipe or by making a noise in it.

The easiest and safest way to identify the location an underground water pipe is the second option, to make a noise in the pipe and listen for that noise with an acoustic listening device. The device that achieves this is called a thumper or pulse wave generator, PWG. Our 'Little Thumpa' simply clicks on a tap and creates that noise, conveniently using your cordless tool battery to power it for as long as you need the sound and with the use of acoustic listening device, the location of the pipe can be traced.
