Pre-action systems are more complex than standard wet sprinkler systems because they rely on both the sprinkler piping and the detection/release components working together properly.
Over time, these systems can develop issues such as:
air leaks
low supervisory pressure
valve problems
detection system faults
slow trip times
compressor issues
water delivery problems
corrosion or obstruction concerns
Routine testing helps confirm that the system will activate properly when needed — while also helping prevent false trips, failed inspections, violations, and costly system impairments.
For NYC property managers, building owners, and facility teams, pre-action system maintenance is not just about compliance.
It’s about protecting people, property, equipment, and building operations.
Don’t wait until an inspection failure or emergency exposes a problem — let JAM Service Company help keep your pre-action sprinkler system tested, maintained, and ready.
