Sprinkler Discharge Volume Calculator
Estimate the total water volume from an accidental fire sprinkler discharge for commercial insurance documentation, adjuster scope discussions, and logistics planning. Flow rates are based on NFPA 13 standard spray heads at typical commercial system pressures.
Most accidental activations involve 1-3 heads
Time from activation to valve closure
K-factor and flow rate from NFPA 13; actual varies by system pressure
Enter 0 for single-floor; water descends to floors below in high-rises
Why Discharge Volume Matters for the Claim
The total volume estimate from a sprinkler event is relevant to two parts of the commercial insurance claim: it contextualizes the scope of structural drying required (a 500-gallon event on a 10,000 sq ft floor has a different saturation pattern than a 5,000-gallon event), and it provides the quantitative backdrop for the business-interruption documentation (larger volume events require longer drying timelines, which extend the BI closure period). Both figures support the adjuster's scope review.
