The standard requires a minimum of 10 L/s to flow from each required feed hydrant outlet, regardless of location. The required flow rates are aligned to the perceived risk of the building type and floor area.
What is the minimum flow for a hydrant?
For one- and two-family dwellings (i.e., a house), the minimum fire flow cannot be less than 500 gpm, and for buildings other than one- and two-family dwellings, fire flow cannot be less than 1,000 gpm.
What is the GPM of a hydrant flow?
Just type in the address and click on the Magnifying Glass. The map display will show the route. Turn by turn directions are displayed at the bottom of the Search Panel. To view all of the hydrants, click in the box in the Places Panel next to Yes under Hydrants in Service.
What is the NFPa standard for GPM?
With baseline fire flow requirements of 1,000gpm for sprinklered buildings and a potential reduction to 600gpm for quick‑response sprinkler systems, NFPA 1 creates a direct link between fire protection design and municipal water infrastructure needs.
Calibrating Distribution System Models with Fire-Flow Tests
In most traditional fire-flow tests, water is released from a single hydrant and pressure is measured at another hydrant. If the single hydrant does not
