The Problem
A property manager overseeing a 6-building rental portfolio was seeing rising water bills and tenant complaints across multiple buildings. No visible leaks in any unit.
Detection Method
Portfolio-wide survey over 2 weeks: thermal imaging of all common areas and mechanical rooms, acoustic scanning of risers, visual inspections of all accessible plumbing.
Results
19 leaks identified across 6 buildings: 8 minor (dripping fittings), 7 moderate (slow pipe leaks), 4 significant (underground service line). All repaired within a month. Total project cost: $14,000. Estimated claims avoidance: $120,000+.
