As a guideline, sprinkler systems should be fed at what pressure unless more specific information is available?

Sprinkler systems are typically designed to operate effectively at a specific pressure to ensure adequate water distribution and coverage in the event of a fire. A pressure of 150 PSI is generally recognized as a standard operating pressure for feeding sprinkler systems unless there are more specific requirements indicated by the manufacturer or relevant codes. This pressure allows for proper operation of the system's components, ensuring that the water can be delivered at the necessary velocity and volume to suppress a fire effectively.

Selecting a pressure that is too low may result in insufficient water flow, whereas excessively high pressure could risk damaging the system or causing unintended leaks. Therefore, 150 PSI serves as a balancing point that meets the operational needs of most sprinkler systems while adhering to established safety standards. Understanding this guideline is essential for firefighters and maintenance personnel to ensure sprinkler systems function as intended in emergency situations.
