What is the minimum PSI needed to utilize the firemain?

The minimum PSI required to utilize the firemain is 125 PSI. This pressure is considered a standard to ensure that the firefighting system can deliver an adequate volume of water to combat a fire effectively. Firemain systems are designed to provide sufficient water pressure to reach various locations throughout a structure or vessel, allowing for the effective deployment of fire-fighting equipment. At 125 PSI, the system is capable of maintaining a suitable flow rate to operate hoses, nozzles, and other firefighting equipment effectively, ensuring safety in emergency situations.
