What does system working pressure refer to?

System working pressure refers to the maximum anticipated static or flowing pressure in a sprinkler system. This is a critical parameter because it helps ensure that the system operates effectively and safely. The working pressure is determined based on the design of the system, including the type of piping and the components used within. Knowing this pressure is essential for ensuring that the sprinkler heads can adequately deliver water to achieve the necessary coverage in the event of a fire.

Understanding system working pressure is vital for maintaining the integrity and function of the sprinkler system. If the pressure is too low, the system may not deliver sufficient water to control or extinguish a fire, while excessively high pressure can damage components and lead to failures in the system. Therefore, it is a critical measure that governs the performance and reliability of fire protection systems.
