Standpipe and Fire Riser Leak Testing
Pressure testing of standpipe systems and fire risers to verify integrity and identify leaks in fire protection systems.
How Standpipe and Fire Riser Leak Testing Works
Standpipe and fire riser leak testing is a specialized service for verifying the integrity of fire protection water supply systems in multi-storey buildings. The standpipe system is isolated, filled with water, and pressurized to the required test pressure (typically 200 psi or 1.5 times the system working pressure). The pressure is monitored over a 2-hour test period per NFPA 25 requirements. A pressure drop indicates a leak in the system. The leak can be localized by isolating sections of the standpipe and re-testing. Once the general area is identified, acoustic listening and tracer gas methods are used to pinpoint the exact leak location. This testing is essential for NFPA 25 compliance in BC commercial and strata buildings.
