What is the minimum pressure required for water coming from a hydrant?

The minimum pressure required for water coming from a hydrant is essential for ensuring adequate flow and effective firefighting operations. A pressure of 20 psi is typically recognized as the standard minimum required pressure. This level of pressure is sufficient to deliver water to the fire apparatus, allowing firefighters to manage the situation effectively.

This standard is based on the need to provide a reliable flow of water to combat fires, as lower pressures could lead to insufficient flow rates, making it difficult to adequately extinguish a fire. Ensuring that the water supply from the hydrant meets this minimum pressure threshold is crucial for maintaining safety and effectiveness during fire suppression efforts.

Higher pressures could be beneficial in some scenarios, but 20 psi is established as the baseline for effective firefighting operations from a hydrant.
