What pressure is not to be exceeded at the outlet of the hydraulically most remote 2-1/2” hose connection?

When determining the pressure that should not be exceeded at the outlet of the hydraulically most remote 2-1/2” hose connection, the correct answer reflects the limitations set by industry standards and safety considerations. The maximum pressure of 175 psi at the outlet is in line with many national and international plumbing codes, which dictate that the pressure in fire protection systems, including hose connections, must be regulated to prevent component failure and ensure safety during operation.

Maintaining pressure within specified limits is crucial for ensuring the effective delivery of water while preventing damage to hoses, attachments, and the overall system. Higher pressures can lead to burst pipes, compromised connections, and ultimately, failures in the firefighting system during critical situations. Therefore, recognizing 175 psi as the optimal upper limit at a remote hose connection aligns with best practices in plumbing design and safety protocols for fire protection systems.
