What component is used to test a deluge system?

A deluge system is an automatic fire protection system designed to suppress fire by releasing a large amount of water through open nozzles when activated. To properly test the functionality and flow of a deluge system, a test drain valve is a critical component.

The test drain valve allows for the controlled draining of water from the system to ensure that the water flow and pressure are adequate during tests. This valve helps verify if the system can deliver the required volume of water in an emergency. During testing, operators can observe water flow and pressure readings, which are essential to ensure the system will operate effectively when required.

Thus, using the test drain valve allows technicians to assess the performance of the deluge system without activating the entire system, making it a standard practice in routine inspections and maintenance.
