Fire Suppression Line Leak Detection Across BC
Locate leaks in buried fire suppression mains without shutting down the system
About This Service
Fire suppression mains and underground feed lines must maintain pressure and integrity at all times. A leak in a buried fire line is both a life-safety issue and a code compliance concern. We locate leaks in buried fire suppression mains using acoustic listening and correlation — methods that work with the system under pressure without requiring a full shutdown — and provide the documentation your fire inspector, insurer and authority having jurisdiction require.
Signs You May Have This Leak

Acoustic listening isolates the leak to a portion of the buried run.

Correlation between two access points (fire department connection, OS&Y valve) calculates the exact position.
- 4
We mark the surface and document the findings for your fire contractor.

A written report suitable for the AHJ and fire inspector is provided.
