Before the first hard freeze: what a property needs in place to avoid an impaired sprinkler system

Wet-pipe failures follow the first sustained freeze every year. The properties that recover fastest are the ones that had a documented plan before the pipe broke.

LAS VEGAS, Nev.

Every sustained freeze produces the same sequence: a wet-pipe sprinkler line fails in an unheated space, the system is drained or impaired, and the property is left with a fire protection gap the authority having jurisdiction expects to be closed immediately.

The cost of that gap is not only the water damage. Once a system is impaired, occupancy often depends on a fire watch, and a fire watch has to be staffed, documented and supervised from the moment coverage is required.

What to have documented before the temperature drops

  • Which spaces are actually heated, and which risers, lines and siamese connections sit in unheated areas.
  • Who is responsible for calling the fire department, and who notifies the authority having jurisdiction that the system is impaired.
  • A fire watch vendor already under agreement, with the licensing and insurance documentation on file rather than requested after the failure.
  • Whether the site will use a patrol model or a posted guard, and how rounds are recorded.

Why the documentation decides the recovery

A fire watch log is a legal record. When an inspector arrives, the questions are specific: who was on site, at what time, how often rounds were made, and what was recorded. A crew that can produce a complete, timestamped log from the first hour of coverage is in a materially different position from one reconstructing a narrative afterwards.

The standard that applies

NFPA 25 governs the inspection, testing and maintenance of water-based fire protection systems, and local adoption controls the actual requirement. Where a system is out of service, the applicable fire code generally permits the occupancy to continue only with an approved fire watch in place. That approval belongs to the authority having jurisdiction for the property, not to the contractor.

Property managers who confirm those details now, while the system is still intact, tend to be the ones who are not negotiating a fire watch at two in the morning.
