What is typically required for an underground fire service main?

The requirement for a minimum pressure and flow test prior to the installation of an underground fire service main is crucial for ensuring the system's reliability and effectiveness during an emergency. This test assesses whether the water supply can meet the necessary pressure and flow rates required for firefighting operations. By ensuring that the underground system can deliver adequate water under pressure, fire safety professionals can ascertain that the sprinkler and hydrant systems will perform as designed when needed.

Conducting this test is part of best practices in fire safety and compliance with relevant codes and standards. It helps to identify any potential issues with the water supply before the system is put into service, thereby mitigating the risk of failures during an actual fire event.
