System Inspections

Typically we perform system inspections during normal working hours. Inspection frequencies vary according to the device: weekly, monthly, quarterly, semi-annual, annual, 3 year and 5 year intervals. NFPA 25 California Edition is the standard for the inspection, testing and maintenance of water-based fire protection systems, and we are well versed with the specific requirements for California.

Wet, Dry, Pre-Action, Deluge Type Systems

Wet and dry systems consist of an integrated network of piping designed in accordance with fire protection engineering standards that includes a water supply source, a water control valve, a water flow alarm, and a drain. The portion of the sprinkler system above ground is a network of specifically sized or hydraulically designed piping installed in a building, structure, or area, generally overhead, and to which sprinklers are attached in a systematic pattern. The system is commonly activated by heat from a fire and discharges water over the fire area.

Pre-Action and Deluge systems add another facet of detection, which require activation devices to discharge water over a fire area.

These systems require a regular service schedule to ensure continued operation and proper protection. NFPA 25 California requires that these systems be tested quarterly, with varying criteria at different intervals.


Fire Hydrant Testing, Maintenance, Installation, and Repair

A commercial fire hydrant is a valved connection on a water supply system having one or more outlets and that is used to supply hose and fire department pumpers with water on private property.

Hydrants require servicing and testing by NFPA 25 California, with some jurisdictions requiring specific tests.

Fire Pump Testing, Maintenance, and Installation

The fire pump provides flow and pressure for the fire sprinkler system. These devices, whether Diesel or Electric, require specific maintenance per NFPA 25 California standards. Typically, diesel-driven pumps require weekly runs and electric monthly.


Back Flow Testing,  Repairs, and Installation

These devices prevent the reverse flow of water that could contaminate the water supply. Where connections are made to the public waterworks, we advise guarding against the possibility of contamination. In addition to regular quarterly inspections, most jurisdictions require backflows to be tested annually.
