National Plumbing employ ultrasonic leak detection to locate hidden leaks. The Ultrasonic Leak Detector is a piece of equipment that our plumbers are fitted with which is a hand-held system that can simply just be aimed in the direction of a suspected leak. If a leak is present, a tone will be heard through the earphones and the LED display will light. This means that testing many pipes and fittings can be done in no time at all.

Many people do not know what ultrasound actually is. Ultrasonic sound is a range of sound that humans actually cannot hear, as a rough gauge we can hear from 20Hz to 20kHz, ultrasonic sound is sound that falls in the 20kHz to 100kHz range.

The Ultrasonic Leak Detector that National Plumbing are fitted with actually converts the ultrasonic sound to a range that is perceptible to people.

Sometimes it is just not possible to have a completely quiet working area, due to this, the leak detector can be adjusted to filter out background noise over different sensitivity sessions.

Ultrasound is loudest at the source of a leak, the sound that comes from the leak is called “white noise” and is generated as a natural result from air escaping from a high pressure area (such as in a pipe) to a low-pressure area (the surrounding area).

Ultrasonic Leak Detectors can detect a leak from up to 6 metres away at any given point. By detecting a leak, you have literally found where you are throwing away money. It is then essential for your own back pocket to get the leak fixed straight away.

If it’s a hot water leak, your energy expenditure will be cut after fixing a leak, this will help lower your electricity bill and save you in the long-run. Thankfully, both carbon-emissions and energy usage has become a priority for leading professionals to cut down on and by fixing these leaks, you are helping the environment and your wallet.

A good leak detector will take a few minutes to evaluate the situation as a whole and judge if any environmental factors will affect the detection process.

Whether it is windy or if there are contaminants or if the suspected leak is out of the line of sight can all affect the leak detection process, however, a great leak detector will know how to accommodate for any environmental factors.
