What is one common cause of sprinkler performance failure?

One common cause of sprinkler performance failure is closed control valves. When control valves are closed, they prevent water from flowing into the sprinkler system, which is essential for the system to operate effectively. This results in inadequate coverage, loss of pressure, or complete failure of the sprinkler heads to activate. Open control valves ensure proper water flow and pressure, allowing the system to function as designed.

While faulty piping, poor installation, and wrong water pressure can also contribute to performance issues, the immediate and straightforward effect of closed control valves can lead to a total incapacity of the sprinkler system to provide the necessary protection. Understanding the role of control valves is vital in maintaining and troubleshooting sprinkler systems effectively.
