When supplying a sprinkler system, the FMO is to pump at what psi?

When supplying a sprinkler system, the correct pumping pressure is 150 psi. This pressure is specified because it ensures that the sprinkler system operates effectively and efficiently. Sprinkler systems are designed to work optimally at specific pressure levels, and 150 psi is considered standard in many circumstances, providing the necessary force to ensure adequate water flow and coverage over the area needing protection.

Pumping at this pressure allows the system to reach its designed pressure requirements for effective fire suppression. Insufficient pressure might lead to inadequate water distribution, which could compromise the system's ability to extinguish or control a fire effectively. On the other hand, excessively high pressures can cause damage to the sprinkler heads or piping system.

Understanding the importance of correct pressure is crucial for fire suppression efforts, as it not only affects the immediate response but also ensures the long-term reliability and safety of the sprinkler system in emergency situations.
