Should a relay engine MPO gate back a 3" supply line to reduce extra pressure to the fire attack engine?

When coordinating operations between a relay engine and a fire attack engine, managing the supply line pressure is crucial for effective firefighting. Gating back, or reducing, the pressure in a supply line helps to ensure that the fire attack engine receives the appropriate water pressure it needs to operate efficiently.

In this scenario, if the main supply line pressure is too high, it could create issues for the fire attack engine, such as causing equipment failure or making it difficult for the firefighters to manage the flow of water effectively. By gating back the supply line, the relay engine MPO can help to stabilize and optimize the water delivery system, ensuring that the fire attack engine receives the right amount of pressure for its operations. This practice is a vital component of teamwork and communication in firefighting operations, as it helps maintain safe and effective water supply conditions.

Therefore, the correct approach is to gate back the supply line to manage and reduce the pressure, thereby supporting the overall effectiveness of the fire attack operation.
