Water leaks in commercial buildings are the leading cause for insurance claims and add up to more than claims for theft and fire combined. Water leaks also have a negative effect on tenants and can require relocating tenants for extended periods of time, which impacts rents. The advent of wireless technology has changed this equation.

This presentation will discuss what to look for in a commercial-grade leak detection system.
