Case study: Our fast and effective leak detection goes swimmingly well for pool owner

When a customer noticed they were losing around 5cm of water from their concrete constructed pool every day, they called the original installer in to find the leak. The search was unsuccessful, so the installer called Polygon. As a first step Tracer gas was employed to measure the pressure of the water inlet and a pressure drop was noted. Further tests to other water feeds were conducted, with no drop in pressure indicated, suggesting that the water feeds were in order.

As a last resort the pool had to be emptied and inspections of the pool lights were undertaken. It became evident that the seal between the cable and flush box was deficient and water had penetrated the lights. After closer inspection it was clear that the light box was leaking. Remedial action was quickly undertaken by the installer.
