Your building’s fire sprinkler system is a vital part of a life safety system. But just like all mechanical equipment, these systems must be maintained in order to provide maximum protection to structures and occupants.

A sprinkler system has many components that, when not properly maintained, can lead to failure. One of these working parts is the check valve. Per NFPA 25 13.4.2.1.and 13.4.2.2, 2009 edition: Valves shall be inspected internally every five years to verify that all components operate correctly, move freely, and are in good condition. Internal components shall be cleaned, repaired, or replaced as necessary in accordance with the manufacturer’s instructions.

The most common component associated with a check valve is the FDC (Fire Department Connection). The fire department uses this as a means to help provide water to the sprinkler system in case of a fire. The check valve is used to hold back system pressure, while the pipe from the FDC to this check valve is open to the atmosphere. When this check valve is not maintained, it could seize and fail, preventing the FDC and the fire department from performing their intended functions.

Complying with NFPA 25 five year check valve maintenance and regular system inspections can assure these components function properly in case of a fire. Please contact us to schedule or quote your five year check valve, or any other inspections that you may need performed.
