Why are check valves used in damage control systems?

Check valves are specifically designed to prevent backflow in piping systems. Their primary function is to allow fluid to flow in one direction while automatically closing when the flow reverses. This is particularly crucial in damage control systems, as backflow can lead to contamination, loss of pressure, or system failures, especially during emergency situations. By ensuring that the fluid only travels in the intended direction, check valves help maintain the integrity and effectiveness of the damage control system, which is vital for operational safety and efficiency.

While options discussing increasing pressure, enhancing fluid flow, or easy cleaning may involve other components or systems, they do not address the core function of check valves, which is focused on maintaining proper flow direction and preventing backflow, thus safeguarding the entire piping infrastructure.
