What is the typical GPM of a sprinkler head?

The typical gallons per minute (GPM) produced by a sprinkler head can vary based on the specific design and purpose of the sprinkler system; however, a common standard for many residential fire sprinkler heads is approximately 15 GPM. This rate ensures that sufficient water is delivered to effectively suppress flames in the early stages of a fire, providing crucial time for evacuation and assistance.

Choosing this standard rate reflects an understanding of the balance between delivering adequate water flow for fire suppression while maintaining system efficiency and managing water supply demands effectively. It's important to recognize that while other rates may exist due to different applications or specific system designs, 15 GPM is widely recognized within the industry for normal sprinkler operation in many settings.
