What does the NFPA 13 cover?

What does NFPA 25 cover?

Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems. NFPA 25 is the baseline for inspection, testing, and maintenance of water-based fire protection systems.

What should be the distance between two sprinklers?

The minimum distance a sprinkler can be installed below a ceiling is 1 inch. The maximum spacing between two sprinklers is determined by the rating on the sprinkler head (usually 15 feet, but there are other spacing distances, depending on the manufacturer). The minimum spacing between two sprinklers is 6 feet.

How do I calculate sprinkler spacing?

Take the sprinkler head watering DIAMETER and multiply it by 0.6 to get the absolute maximum distance that should ever occur between any two adjacent sprinklers. (Remember most manufacturer’s give you the radius of the sprinkler, you need to multiply by 2 to get the diameter.)

How many sprinkler heads can you put on one line?

At different pressures, the sprinkler head and nozzle will consume different amounts of water. For example, at 35 pounds per square inch (PSI) the 5000 Series Rotor using the 3.0 nozzle will use 3.11 gallons per minute (GPM). If your home’s water capacity was 10 GPM, you could place 3 heads per zone.
