What is the supply engine pressure sent to the attack pump?

The supply engine pressure sent to the attack pump is typically set at 50 psi. This pressure is important because it provides a reliable and consistent flow of water to the attack pump, which is essential for effective firefighting operations. A pressure of 50 psi strikes a balance between sufficient pressure to deliver water effectively at the nozzle while minimizing the risk of equipment damage or excessive strain on the system.

Setting the supply pressure at this level ensures that firefighters can maintain adequate flow rates while also enabling the pump to operate efficiently. In firefighting operations, maintaining a proper pressure is crucial for achieving optimal performance during water delivery. Higher pressures, such as 75 psi or 100 psi, could lead to complications, including increased wear on pump components and the potential for hose failure, while lower pressures may not provide enough force to effectively combat a fire. Therefore, 50 psi is standard practice as it meets operational requirements without compromising safety and performance.
