The Problem
A Vancouver hotel had a water stain on a 7th-floor ceiling. Hotel was at 94% occupancy. The leak needed finding without blocking rooms.
Detection Method
Overnight tracer gas injection into the 8th-floor bathroom supply lines. The hydrogen-nitrogen mix escaped through the leak and was detected below. Entire process took 2 hours.
Results
No rooms blocked. One tile removal for repair. Hotel added us to emergency contacts for all three BC properties.
