Why is it important to install valves on fire service mains?

Installing valves on fire service mains is crucial for isolating segments of the system for maintenance. This allows for the repair or replacement of sections of the piping without affecting the entire fire protection system's operation. In the event that specific areas of the fire service main require maintenance or repairs, having valves installed enables personnel to shut off the water supply to only the affected sections, ensuring that the remaining system remains operational. This is vital for maintaining readiness and functionality during emergency situations.

While enhancing water flow during fire events is significant, it is not the primary reason for installing valves. The primary focus of valves in this context is to facilitate maintenance and ensure the reliability of the overall system. Similarly, adjusting pressure within the main system may be essential, but it typically falls under different system components such as pressure regulators rather than the primary function of valves. Lastly, while valves can provide additional access points for firefighters, their primary role is more about isolation and maintenance than access.
