Is post-fire water damage from sprinklers worse than fire damage would be without sprinklers?
A residential sprinkler flows 10 to 26 gallons per minute for approximately 10 minutes (depends on how soon responding firefighters turn off the system). The fire department uses hoses that flow 250 gallons per minute or more; often 10 times the water used by a residential sprinkler. The property loss in a home with residential sprinklers is only a fraction of the loss in a home with no sprinklers.
