Fire Sprinkler Systems

A fire sprinkler system is an active fire protection method, consisting of a water supply system providing adequate pressure and flowrate to a water distribution piping system, to which fire sprinklers are connected. Although initially used only in factories and large commercial buildings, systems for homes and small buildings are now available at a cost-effective price.

Fire sprinkler systems are extensively used worldwide, with over 40 million sprinkler heads fitted each year. Fire sprinkler systems are generally designed as a lifesaving system but are not necessarily designed to protect the building. Of buildings completely protected by fire sprinkler systems, if a fire did initiate, it was controlled by the fire sprinklers alone in 96% of these cases.***

Inspection Cycles

All fire sprinkler systems require:

  • Weekly inspection of gauges (in house)
  • Annual inspection
  • 5-year valve, pipe, FDC internal inspections
  • 5-year FDC Hydrotest
  • 5-year Standpipe Flow
  • 5-year Fire Hose Hydrotest
  • 3-year Dry System Full Trip
  • 5-year gauge replacement

Depending on the system you have and the requirements from your insurance provider, your sprinkler system may also require quarterly or semi-annual inspection, testing, and maintenance.

Common Deficiencies

A deficiency is identified during regular inspections when the devices and components do not meet acceptable standards. Here are a few commonly found deficiencies for fire sprinklers:

  • Damaged or incorrect sprinkler heads
  • Painted or loaded sprinkler heads
  • Obstructed spray pattern
  • Needing 3 Yr. & 5 Yr. Services
  • Internal blockage and corrosion
