The Problem
A fitness centre had water pooling at the pool deck. Water bill had jumped 60% even when pool was unused.
Detection Method
Thermal imaging revealed a warm path from a hot water line beneath the tile. Acoustic correlation confirmed a pressurized leak at 2.4m depth.
Results
200mm core hole access. Corroded return line replaced. Bills returned to normal. $4,200/year in wasted heat and water saved.
