Drain valves and test connections must be?

Drain valves and test connections must be approved to ensure they meet the required safety and performance standards set forth by local building codes and regulations. This approval process typically involves certification by a recognized organization that evaluates the materials and design of the valves and connections. By requiring approved components, it ensures that the fittings can withstand the pressure and environmental conditions they will encounter in a fire protection system, promoting reliability and safety.

The need for approval also helps standardize practices across installations, ensuring that all components are compatible and work effectively within the fire suppression system. This not only enhances the effectiveness of fire protection systems but also guarantees that they are compliant with legal requirements. Components that are not officially approved may not function as needed when a fire event occurs, potentially compromising safety.

While standardization, DIY-friendliness, and universality may seem beneficial, they do not guarantee that the components meet necessary technical specifications or certification requirements that are crucial for the proper functioning of a fire suppression system.
