What is the purpose of pressure testing fire service mains?

The purpose of pressure testing fire service mains primarily focuses on verifying the integrity of the piping system and checking for leaks. During this process, the system is filled with water and subjected to a specified pressure level for a certain duration. This allows inspectors to identify any weaknesses or faults in the piping, fittings, or joints that could compromise the system’s performance during a fire emergency. This testing ensures that the fire service mains can withstand the pressures they would encounter in operation and can deliver the necessary water volume and pressure when required.

Pressure testing highlights any potential issues before the system is put into service, ultimately protecting the reliability and functionality of the fire protection system. Such proactive measures are critical in maintaining safety standards and ensuring effective fire response capabilities.
