What pressure is typically associated with 1½" hose stations in a sprinkler system?

In sprinkler systems, the pressure associated with 1½" hose stations is typically around 100 psi. This pressure level is considered effective for delivering adequate flow rates necessary for firefighting efforts, while also ensuring proper operation of the hose system.

At 100 psi, the system can effectively supply the volume and pressure needed for managing potential fire hazards, as it balances the requirements of both the hose's capacity and the necessary flow rates to combat flames effectively. Adequate pressure is vital; too little pressure may hinder the flow, making it difficult to control a fire, while excessively high pressure can lead to equipment wear, potential failures, and safety hazards.

While other pressures may be seen or recommended in different contexts or systems, 100 psi is the standard recognized for efficient operation at 1½" hose stations in most firefighting scenarios, ensuring performance is optimized for immediate response.
