About Us

German - Just Plumbing - www.justplumbing.co.zaThe core of the business is water leak detection.
This is done using very specialised and sophisticated equipment including tracer gas, acoustic listening and thermal imaging.

What is tracer gas testing?

If a water pipe is not under pressure or the noise from the leak cannot  easily be  heard with an acoustic listening device, then Tracer gas can be a very useful technique to locate water leaks in water Supply Pipes as well as underwater Heating Systems etc

The Tracer gas is introduced into the pipe with the leak from a cylinder of gas. This gas is a mixture of hydrogen (5%) and nitrogen(95%). Being non toxic, non corrosive and non flammable it is totally safe to use in water pipes. The tracer gas contains hydrogen, which  being the  lightest and smallest molecule in the atmosphere, will exit at the leak point and make its way to the surface , through concrete, tarmac, paving and grass,where it is detected by the specialised gas detector.

What is acoustic testing?

An electro acoustic water leak locator is used to amplify the noise from water leaks in pressurised pipes.
The amplified noise is transmitted to the headphones worn by the operator as an audible signal and is also displayed on the devices digital display as a visible readout. This equipment is very sensitive and is sometimes best used at night.

What is Thermal Imaging?

Since damp/wet areas are colder than any surrounding areas the colder areas can be identified by means of a thermal imaging camera. By taking thermal images of suspect areas and analysing the difference between hot and cold areas, the source of a leak can often be located. Analysis and the correct interpretation of these images is important as incorrect interpretation can lead to false indications of leaks.

Thermal imaging is also widely used to trace the locations of, especially, hot water pipes and also building insulation defects and electrical problems.

What is a moisture meter?

This is a hand held device that is held over areas that are possibly damp. The device creates an electromagnetic field which is then used to produce a moisture content reading.  Any dampness is indicated to the operator as an audible signal. This device is used to determine if, especially, walls do indeed contain any dampness.
