Chasing drips

A busy day,from assessing large diameter Watermeters to preparing to fix this serviceline and stormwater. I was at a School checking out a meter, the caretaker saw my leakdetection unit and asked what it was,when I told him he said; you're just the person I need. It turned out the School had a huge leak (50 litres per minute) on a heating pipe from the boiler. I found the leak for them and not in the place the Plumber was planning to dig up, so that was a good result.
