The Problem
A hotel property manager had a water stain on a 7th floor ceiling below an 8th floor guest bathroom. Hotel was at 94% occupancy — no rooms could be blocked.
Detection Method
Overnight tracer gas injection into the 8th floor bathroom supply lines. Detected at the ceiling penetration below. Entire process took 2 hours — no guest disruption.
Results
No rooms blocked. Single tile removed for repair. PM added Leak.ca to emergency contacts for all three hotel properties in portfolio.
