Detection methods


 

Before starting destruction work to find the leak or to fix the water damage, electronic leak detection may help to pinpoint the origin of the leak with the goal to minimize damage and be surgical with repairs. Here is a list of the methods used.

Pressure testing is done to determine whether there is a leak in the water supply pipes.  The concept is based on the idea that if there is a leak, it will loose the pressure, similar to a car tyre. It is quite accurate and will pick up even a small leak such as a dripping tap.

Endoscopic video camera is a small camera on a reel (up to 20m) that can see inside pipes for obstacles such as roots, blocks, cracks etc. There is a also a transmitter on the camera which is used to locate the camera under ground as well as its approximate depth.

CAMERA

 

Infrared thermal imaging camera is a special camera that sees the invisible. In a nutshell, our eyes sees the visible spectrum of light while the Infared camera sees infrared waves that is invisible to us. As a result you “see” the damp in the wall and the area it covers even before you have visible water damage. In the same way, you can often trace buried pipes and often see leaks in the floor. This technology, once reserved for the military and NASA has now become affordable enough to be used by mere mortals.

 

Fluo

Fluoresceine is a dye colorant that is used to confirm a leak from water infiltration such as from rain, showers and bath tubs. It also excellent to confirm the path of drains. It is also used in pools to test the waterproofing of lights, fittings, cracks and other anomalies in the pool structure

 

Gas

Tracer gas is a neutral non-toxic gas that is injected into the leaky pipe. The gas will escape at the location of the buried leak. The hydrogen detector is then used to detect the location of the gas, which indicates of course then where to dig.  This is usually excellent for hidden exterior leaks in the garden as well as leaky pool pipes.

Electro-magnetic tracing is a non destructive method to trace the path and depth of underground pipes. This is especially a helpful aid  with the tracer gas detection. If you already know the path of the pipe, the gas detection is much easier and effective.

This is the locator that is also used to find the transmitter on the endoscopic camera. It  is also used at times to find hidden manholes and missing septic tanks.

Acoustic leak detection is to the leak specialist what a stetoscope is to a doctor. It greatly amplifies the sound of underground leaks and may help to localise a hidden leak by finding the loudest vibrations in the pipe.
