What is a common consequence of closed valves in fire protection systems?

A common consequence of closed valves in fire protection systems is system operation failure. When valves that are part of a fire protection system are closed, they prevent water from flowing through the system. This blockage can lead to a situation where, in the event of a fire, the system cannot deliver the necessary water to suppress the flames. The primary purpose of a fire protection system is to ensure that water is readily available when needed, and any obstruction, such as closed valves, directly compromises this capability.

In contrast, while increased pressure in pipes could theoretically occur due to the closure of a valve, it typically does not result in improved system functionality and can even lead to damage. Similarly, while it might seem that closed valves could help reduce maintenance costs by limiting water flow and potential leaks, such an approach endangers the integrity and readiness of the fire protection system. Therefore, identifying valve positions and ensuring they are open as required is crucial for the reliable operation of these critical systems.
